Chapter 1 &#; What are Custom Plastic Bags?

A custom plastic bag, poly bag, or pouch is a flexible container made from thin plastic film, nonwoven fabric, or plastic textiles, designed to suit specific product needs. These bags are used for storing and transporting various items, including chemicals, food, powders, ice, magazines, and other goods. Custom plastic bags are widely utilized in packaging.

Personalized plastic bags are handy and adaptable in practically every business. They not only offer their goods storage and transportation, but they also present a fantastic advertising opportunity. Businesses can increase brand awareness and leave a positive impression on clients by having a company name, logo, or image printed on their plastic bags. Plastics companies offer LDPE (Low-Density Polyethylene) and HDPE (High-Density Polyethylene) custom-made plastic bags in sizes up to 56 inches wide and gauges ranging from 0.75 to 8 mil. Towels, handkerchiefs, and men&#;s briefs are frequently packed in these LDPE (Low-Density Polyethylene) custom plastic bags with punch holes so they may be hung on pegs in shop showrooms. These bags are popular due to their high quality, affordability, and durability. Numerous performance additives, different venting techniques, fantastic films, and print colors are all available to personalize these poly bags even further.

Plastic bags are versatile pouches made from thin polymer sheets, offering flexibility for various uses across industrial, commercial, and residential settings. They are commonly used for transporting, storing, shipping, and packaging items. Additionally, plastic bags often provide waterproofing and protection from the elements.

Chapter 2 - What are the properties of custom plastic bags?

Polymers are large molecules composed of repeating monomeric units, forming the foundation of custom plastic bags. In these bags, the repeating units are typically ethylene or ethene. These polymers are made up of long chains of carbon atoms, with each carbon atom bonded to two hydrogen atoms, creating polyethylene. Different types of polyethylene can be produced from ethylene, including high-density polyethylene (HDPE), medium-density polyethylene (MDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE). For instance, HDPE is commonly used for grocery bags, LDPE is used for dry cleaner garment bags, and LLDPE is used for thick, glossy retail bags found in malls.

The primary difference among these materials lies in the degree of branching in their polymer chains. Branching occurs when secondary polymer chains attach to the main backbone, creating various polymer structures such as star, H-shaped, pom-pom, and comb-shaped polymers. LDPE chains exhibit branching, while HDPE and LLDPE chains are linear and unbranched. Branching impacts physical properties like tensile strength and crystallinity; increased branching typically results in lower tensile strength and reduced crystallinity. This explains why custom garment bags from dry cleaners, made from branched LDPE, are thin and delicate.

Polymerization is a chemical process where small molecules, called monomers, bond together to form large, chain-like or network structures known as polymers. Traditionally, linear unbranched polyethylene was produced using Ziegler-Natta polymerization. However, metallocene-catalyzed polymerization is a more recent and advanced technique that enables the production of polyethylene with higher molecular weights. Similar to the Ziegler-Natta method, the metallocene approach often involves the use of metal complexes as catalysts to create new copolymers.

Free-radical polymerization is the method used to produce branching polyethylene, known as LDPE. As the oldest technique among the three, it uses an initiator molecule, such as benzoyl peroxide, instead of a metal complex. When benzoyl peroxide decomposes, it generates free radicals that initiate the polymerization process. These radicals react with the carbon-carbon double bonds in ethylene, creating new radicals that further react with additional ethylene molecules. This process forms a chain of carbon atoms with single bonds, which continues to grow until the reaction ceases, often when two free radicals combine.

Medium Density Polyethylene (MDPE)

Low-density polyethylene (LDPE) is more transparent compared to medium-density polyethylene (MDPE), which in turn is less transparent than high-density polyethylene (HDPE). As a result, MDPE bags are not ideal for carrying or storing bulk items due to their limited stretchability and lower strength. Despite this, MDPE is commonly used for trash bags and is often seen in the packaging of consumer paper products, such as toilet paper and paper towels.

Chapter 3 - What are the different types of custom plastic bags?

Frosted Custom Plastic Bags

Frosted plastic bags are a popular choice for product packaging due to their durability and resistance to wrinkles. Made from high-density plastic, these bags are tough and long-lasting, providing excellent protection for goods. They are puncture-resistant and can be recycled, making them an environmentally friendly option. Unlike paper bags, frosted plastic bags are exceptionally strong and less likely to tear.

Moreover, frosted custom plastic bags meet the requirements for reusable bags in many plastic bag ban regulations. Their potential to replace single-use plastic bags makes them a preferred choice among retailers, thanks to their reusability. These bags are also cost-effective. Some frosted custom plastic bags are adorned with tissue paper or ribbons. Combining strength with environmental benefits, frosted plastic bags are an excellent option for gift-giving. They also serve as versatile carryall bags for various items, whether at home or during shopping trips.

High-Density Custom Plastic Bags

High-density plastic bags have a wide range of applications due to their lightweight, cost-effective, and durable nature. These bags can be customized to meet specific needs, with options available in both thick and thin varieties. High-density custom plastic bags can also feature a frosted finish for added strength. For a more refined look, customized handles and various sizes are available.

Frosted High-Density Custom Plastic Bags

Frosted high-density plastic is both durable and sturdy, making it an excellent choice for packaging food or clothing. These bags offer a modern and stylish look, often featuring attractive hot-stamped designs and the added elegance of colored interior tissue. They are equipped with die-cut handles and reinforced with high-density plastic and cardboard bottom inserts for added strength.

Discreet Plastic Bags

Discreet plastic bags, which are reclosable, have significantly improved the convenience and functionality of daily life for many people. These bags are effective in preserving food and minimizing waste. Additionally, discreet bags are commonly used and have become standard in households, serving as storage solutions or, occasionally, as trash bags.

Wicketed Plastic Bags

A wicket consists of a metal frame shaped like a "U" that holds a stack of plastic bags. These wicketed bags have one open side and three sealed sides. Items are placed into the bag through the open side. Designed for high-speed industrial use, wicketed plastic bags offer a simple structure that enhances packaging efficiency in automated production settings. They also reduce handling time and comply with USDA regulations for food storage.

Gusseted Custom Plastic Bags

Gusseted plastic bags feature an additional piece of material providing more space and strength to a bag. The edges and bottoms of these bags are especially well-designed for the packaging of larger and bulkier objects. Gusseted plastic bags often appear almost as pouches. Packaging candy assortments, garden soil, hardware, tools, and crafts are common uses for gusseted plastic bags.

Zip-Top Custom Plastic Bags

Zip-top plastic bags are primarily made from polyethylene. They feature a distinctive zipper-style closure at the top, which makes them versatile and easy to personalize. The zip seal ensures that the contents are protected from external elements and prevents any leakage, making these bags highly functional for various uses.

Food Grade Custom Plastic bags

Food-grade custom plastic bags must adhere to rigorous standards and requirements. To qualify as food-grade, a custom plastic bag must be protective, durable, and chemically resistant. Protection involves the bag's ability to block moisture and contaminants without degrading. It should withstand the manufacturing process, food packing and storage, and transportation without compromising its integrity.

The chemical standards for food-grade custom plastic bags ensure that the material does not leach or allow chemicals to seep into the food. This includes preventing any changes in the flavor, taste, or appearance of the food. It must be confirmed that the plastic material will not negatively impact consumers in any way.

The approval of custom plastic bags for food use is overseen by the Food and Drug Administration (FDA) and other regulatory agencies. They use three criteria to determine if a custom plastic bag meets the requirements for food contact.

• Material - All ingredients and additives are tested to ensure the material is safe and will not affect the taste, smell, or color of food. The testing process includes subjecting the material to changes in temperature, humidity and moisture, and chemicals, oil, and alcohol. The various tests are designed to test the durability of a custom plastic bag as well as its expected lifetime of use.
• Manufacturing Facility - The manufacturing facility has to meet strict cleanliness standards and have practices in place for the prevention of contamination. ISO from the International Standards Organization (ISO) stipulates the minimum standards for the product of food grade custom plastic bags.
• Certification - Once the food grade plastic has been manufactured, it is checked for its compliance with the certification for food grade and safety, which is a food safety certification from the Food Safety System Certification (FSSC ) that was established by the Global Food System Initiative (GFSI). To maintain this certification, custom plastic bags are regularly checked throughout their lifetime of use.

The use of food-grade custom plastic bags is increasing rapidly due to global challenges such as hunger, necessitating the transport of food products worldwide. These bags are commonly found in supermarkets, pharmaceutical distribution centers, and environments requiring contamination control. They have become an essential component in food production and distribution.

Chapter 4 - How Custom Plastic Bags are Printed?

Adding Color

Plastics can be colored using various methods based on customer requirements and the intended use. The three most common methods for coloring plastic are masterbatches, cube mixes, and pre-colored resins.

Masterbatches

Masterbatches, often called concentrates, are the most widely used technique for plastic coloring. This method involves pre-mixing pigments with a resin. To achieve effective mixing, the pigments and polymer resins are heated before being combined.

Cube Mixes

Cube mixes, also known as salt and pepper mixes, allow customers to precisely control their output by blending a masterbatch with polymers. The polymer retains its original properties as it remains solid throughout the process.

Pre-Colored Resins

Pre-colored resins are created by incorporating pigments directly into the polymer, which is then forced into the plastic resin. This method enables immediate matching of the desired performance and simplifies production.

Extrusion

The extrusion process shapes plastic film by heating and forming it to produce plastic bags.

Hopper

To initiate the extrusion process, plastic resin pellets are first loaded into a hopper, which is a container for holding bulk material. Positioned at the beginning of the extruder barrel, the hopper has evolved from simple cone-shaped holes that required manual loading of resin pellets. Modern hoppers now feature advanced designs and feeding mechanisms, reducing the need for manual loading.

Extruder

The extruder is the heating mechanism required for the production of plastic bags. It comprises a large tube called the barrel and an auger, which is a helical screw. The auger gently advances the resin pellets toward the die as they drop from the hopper into the barrel. Heating elements are positioned along the barrel on either side, gently melting the resin pellets to create the molten liquid that will reach 500°F and be pushed into the die. For the heated resin to pass through the circular die at the extruder's end, it must be sufficiently malleable. The molten plastic is driven through a spherical, circular die at the barrel's end before it enters the cooling tower. Before reaching the die, a screening or breaker plate is used to eliminate any potential contaminants to guarantee the purity of the molten resin. The breaker plate has two purposes: it cleans up debris and shields the die from the extremely high pressure that the extrusion process generates.

Die

As the molten plastic resin moves through the extruder barrel, pressure is applied to push it past the screen or breaker plate and into the die, which shapes the product, such as custom plastic bags. The die can be positioned either vertically or horizontally within the cooling tower's long cylinder. It uses compressed air to form the plastic material into a tubular shape and determine its thickness before directing it into the cooling tower. The diameter of the tube depends on the type of plastic being processed. The plastic sheet undergoes both axial and radial stretching, resulting in a tube that is considerably larger than the die ring.

Cooling Tower

As the process continues, the molten plastic resin is driven past the breaker plate and die as it leaves the extruder and enters a cooling tower&#;s cylinder bottom. There, the plastic material cools and assumes the shape of the finished plastic bags. It is also at this point where it is determined that the proper bag thickness has been reached and that bags do not contain holes. The cooling process' pace is also affected by the cooling tower's height, which ranges from 25 to 35 feet. The speed of the plastic material&#;s speed of movement through the cooling tower determines the plastic film's thickness. The plastic bags will have thin walls and be extremely light when they expand quickly. The final bags will have full walls and be more durable if the molten plastic is allowed to expand gradually.

Gussets Addition

The gussets of a plastic bag are folds, wrinkles, indentations, or expansions added to its sides to increase its volume while allowing the bag to lay flat for storage. These gussets are formed by boards in the cooling tower walls that puncture the fully-inflated plastic as it moves towards the nip rollers, causing the material to flatten against the tower walls.

When the material exits the cooling tower, the nip rollers compress the two overlapping sections of the plastic to form the gusseted fold. This process is assisted by boards that create the desired crease pattern. A common type of gusset, known as the "side gusset," allows the plastic bags to expand outward on both sides, enhancing their strength and durability compared to other bag types.

Nip Rollers

As the newly-formed plastic film rises towards the nip rollers positioned at the top of the cooling tower, it is given time to cool down. These rollers play a crucial role in providing traction, maintaining tension, and facilitating the winding process. Their primary purpose is to exert pressure to firmly and securely roll the plastic film. The nip rollers generate the necessary force to elevate the cooled film so it can be coiled for further processing.

Nip rollers are responsible for removing air bubbles, blisters, and other imperfections from the plastic film. By drawing air out from the plastic web as it moves through the cooling tower, these rollers help control the firmness of the roll. The key challenge in designing nip rollers lies in achieving the perfect winding pressure to ensure that excess air is removed and the roll is tightly wound, all while preserving the integrity of the plastic film.

Preventative Measures

Polyethylene material may be treated with additives throughout their production process, including: Anti-Blocking Additives: Blocking is the adhesion of polyethylene. An anti-blocking ingredient microscopically roughens a plastic's surface to make it simpler to separate the bags. Anti-Static Additives: Anti-static additives reduce surface resistivity and static decay through many static-sensitive applications. UV Inhibitors: UV inhibitors (ultraviolet inhibitors, or UVIs) stop plastic bags from deteriorating or fading when exposed to the sun. UV inhibitors will stop white bags from becoming yellow due to prolonged light exposure. In addition, they guard against tampering with the bag's printed and written contents by providing an extra layer after printing which makes it more difficult to make &#;edits&#; on a bag.

What factors influence the cost of printing plastic bags?

The price of custom plastic bags depends on various factors, including the following:

• The cost of printing and producing all plastic bags is influenced by the plastic bag's size and thickness.
• Plastic printing and material prices fluctuate daily. Plastic bags for packaging and printing are produced in relation to changes in the price of raw materials. The amount and quality of the raw ingredients that goes into making the plastic directly affects the cost of the bags.
• What is the required color accuracy and what printing style will be used? For example, silk screen printing is a cheaper option than other methods due to its ability to use pre-prepared stencils and plates. Due to the employment of more expensive technology and materials, other printing processes such as helio and flexo printing are more expensive. Of course, these more expensive processes generally create a better printed bag product.

Chapter 5 - What are the important points to consider when printing promotional custom plastic bags?

As previously mentioned, the goal of customizing plastic bags with prints is to capture attention and turn casual viewers into dedicated customers. Hence, the visual appeal and attractiveness of these printed plastic bags are essential. They are designed to be eye-catching, often more vibrant and durable compared to standard bags or other advertising methods.

When designing these eye-catching promotional plastic bags, the following aspects should be meticulously evaluated:

• Printed custom plastic bags must feature vibrant, high-quality printing.
• The personalized plastic bag's material must be of the highest caliber and produced using premium raw materials.
• When printing on these plastic items, it is preferable to utilize an eye-catching and distinctive design.
• Logo printing, text, image printing, or a mix of these elements can all be used to decorate custom plastic bags.
• A custom plastic bag's printing background should be either white or colorful because dark images show up better on lighter backgrounds and vice versa.
• Use a cheaper printing method, such as silkscreen printing, when possible. A mesh is used in the printing process known as silkscreen printing (often referred to as serigraphy and serigraph printing). Serigraphy printing is a process of transferring ink (or dye) onto a substrate, except in places that are blocked off from the ink by a blocking stencil. The open mesh holes on the screen are filled with ink using a blade or squeegee motion, and the screen briefly touches the substrate along a line of contact when the motion is reversed. After the blade has passed, the screen springs back, wetting the substrate and causing the ink to be pulled out of the mesh holes. Since one color is printed at a time, multiple screens are required to produce a multicolored image or pattern.
• Custom printed plastic bags may be the least expensive way to advertise due to their durability and ability to be reused numerous times. They also provide a means to insert an advertiser&#;s business cards or other forms of advertising. As a result, advertising with custom plastic bags is one of the most crucial and fundamental ways to boost a company's profitability and economic efficiency.

Chapter 6 - What are the benefits of using printed custom plastic bags as advertising material?

• A two-minute TV commercial can't compare to the impact of a printed custom plastic bag featuring a company&#;s logo, contact information, and/or other branding. While TV advertisements eventually stop being broadcast or distributed, a custom-made plastic bag can last for years or even decades. Customers are reminded of a company and the value of the services and goods provided whenever they see a personalized plastic bag. Every time a customized plastic bag is seen, consumers or potential customers are quickly reminded of that company and the quality of the services or goods that this organization offers.
• The most important advantage of personalized plastic bags for an organization is found in the cost reduction provided. In the long run, custom-printed plastic bags are a vastly more affordable branding option than TV ads or other types of marketing.
• Benefits of Custom Plastic Bags for Business Branding: The name and/or logo of a company should convey its essence. Branding contributes to the narrative and conveys the principles a company upholds. The chance to establish and strengthen a brand identity is provided by the distinctive size, color, and design options offered by personalized plastic bags. Unique packaging can enhance brand identity and communicate to clients what makes a company stand out in today's highly competitive market. A customized bag representing a business can take the place of generic shopping bags, leaving customers with an impression that will stick with them longer than other means of marketing.
• Enhanced Customer Assumption of Quality: Custom plastic bags can significantly improve a brand's overall image. Custom-printed shopping bags are associated with upscale stores and long-standing companies among current and potential customers. A corporate logo with a bold splash of color speaks volumes about a brand and may both retain current consumers and draw in new ones. There are countless alternatives and possibilities when it comes to creating personalized plastic bags for businesses. Any color, size, shape, thickness, or style of custom-printed bag can be selected. This enables companies to design the ideal plastic bag for their own branding needs. The most significant benefit is that this distinctive packaging will distinguish a corporation&#;s brand from its rivals.
• Repeated Value From Custom Printed Bags: Custom plastic bags are the best option for businesses seeking plenty of value and usability for their marketing dollars. Clients may utilize these multipurpose and adaptable bags for various purposes to make daily life easier. Additionally, by offering a reusable packaging and transport solution, clients will be grateful and more inclined to patronize the company again. When a customer is using a company's customized plastic bags, free promotion is being received by the business as well. As long as the bags with custom printing are used, the business will continue to get this free publicity.
• Asserting the Environmental Advantages of Custom Plastic Bags: A business or brand can further its branding by selecting environmentally-friendly, custom-printed plastic bags. Every bag size can be used by a business to make the ideal custom-printed, post-consumer plastic bag. This might be extremely helpful and advantageous if the brand already runs on an energy-efficiency platform or is associated with green activities. Otherwise, the ideal, affordable entry point could be adopting &#;environmentally-green,&#; custom-made plastic bags, even if the company doesn't use other green programs. Many customers might be prepared to pay more for the services and goods when a company adequately markets their new green efforts with materials inserted into these bags or by simply employing their custom plastic bags as durable, multiuse, reusable bags.

Chapter 7 - What are the business benefits of using custom plastic bags?

Branding plays a crucial role in business success, aiming to associate a logo with the product it represents. Over time, various techniques have been employed to embed logos, symbols, or images in the public&#;s mind, with some methods being elaborate and expensive.

Custom-designed plastic bags have proven to be an effective way for many brands to showcase their logos. By utilizing high-quality printing and vibrant colors, these bags can effectively capture public attention and enhance brand visibility.

• Promotional Information: For several years, advertisers put their promotional information on posters that are displayed in store windows. Small or large custom plastic bags are used for the same purpose with simple information clearly printed on a bag.

  Modern advanced printing technologies make it easy to place business information, promotions, product details, and locations on custom plastic bags for easy access.

  The use of informational bags can be of help to clients of all types from business to business to retail and commercial sales. Hours of service, numbers, and addresses can be added to a bag in multiple colors and easy to read.

• Lightweight: Since custom bags are lightweight, they are easy to access and convenient. Each time a client uses a lightweight custom plastic bag, they are exposed to the information of the company the bag represents.
• Reusable: Promotional plastic bags are reusable and serve several purposes before being replaced. As with lightweight, using a custom bag over and over exposes a customer to the significance of a brand. In many ways, it is continuous free advertising and reinforces the importance of a buying choice.
• Many Varieties: Custom plastic bags come in different sizes, styles, construction materials, and colors. They are made of a variety of plastic resins with the various types of polyethylene being the most common.
• Low-Density Polyethylene (LDPE)
• Polyethylene High-Density (PEHD)
• High-Density Polyethylene (HDPE)

  Custom plastic manufacturers give clients the opportunity to choose the type of custom plastic bag they prefer including anti-static bags, FDA bags, resealable bags, pallet covers, mattress bags, medical bags, and vacuum pouches. Each type of material and style can be customized with a business logo and other pertinent information.

• Storage and Packaging: Well made and durable custom plastic bags can be used to carry and secure purchases but are versatile enough to be used for other applications such as packing and carrying items during long distance travel, storage, and keeping materials separate and clean.

  Properly produced custom plastic bags can help simplify daily storage, packaging, and transportation hassles. When they are used for travel, they expand the exposure of a brand and make it visible to a wider audience at no additional cost.

Chapter 8 - What are the disadvantages of using custom plastic bags?

• The material in custom plastic bags is designed to last. When improperly handled, the bags can end up as a hazard to the environment.
• Plastic bags are prohibited in some countries.
• A disadvantage of plastic bags is their low melting point.
• Plastic bags are made of non-biodegradable materials that can be recycled and should not be disposed of at dump sites.
• Toxic compounds are used in the production of plastics such as stabilizers, colorants, and various chemicals.
• Custom plastic bags are a short term packaging method that is used and disposed of. Manufacturers, retailers, and government agencies are working closely to ensure recycling and control of used plastic bags.

Frequently asked questions

You're in the right place if your business is ready to switch to eco-friendly poly mailers. At EcoEnclose, we live and breathe earth-friendly shipping solutions. Before you make the switch, you may have some questions. We have the answers.

Why should my business start using sustainable mailers?

Poly mailers are quickly becoming the most economical way to ship most physical goods. Since they&#;re cheaper to produce than corrugated cardboard, they can even give businesses enough wiggle room in their budget to customize their packaging supplies.

Poly mailers are lighter and thinner than boxes, so they cost less to store, transport, and deliver. And if you get yours from EcoEnclose, you can save on returns, too. Customers who wish to return or exchange their products can send them back in the same mailer using the second adhesive strip to seal them.

Using a concrete example, Let&#;s look at the potential savings. If you want to ship a men&#;s size large polar fleece from a warehouse in Louisville, CO () to a customer in New York, NY (), here&#;s what you can expect to spend on each type of packaging:

That price difference might seem negligible when shipping a single item, but you can see how the savings quickly add up when you send out thousands&#;or hundreds of thousands&#;of products.

An added benefit of using poly mailers for especially lightweight items is worth noting. If your products are less than 13 ounces, you can use USPS First Class Mail, which starts at just $0.58 for one- to three-day shipping.

What happens at the end of a poly mailer&#;s life?

Mailers with dual adhesive strips can be used twice. After their initial shipping, recipients can use them again to send back products or ship personal packages to others. Once poly mailers reach their second destination, they can be recycled at facilities that accept plastic bags and films. Encourage your customers to save their mailers alongside their grocery bags and make occasional drop-offs at the facility nearest them.

How are poly mailers recycled?

Depending on your curbside recycling program, they can be recycled residentially or at your local grocery store that accepts plastic bags.

We also are the only packaging company on the market offering a poly take-back program that allows your customers to stuff their EcoEnclose poly mailers with plastic film and ship them to our warehouse for recycling.

What can I ship with a poly mailer?

Poly mailers are the ideal shipping solution for fabric-based goods. Sometimes, they can also ship boxed items that need an outer layer, like shoes, prints, and stationary.

These types of mailers are not suitable for fragile items. If the products you ship could break en route, you probably want to use actual corrugated boxes with protective packaging and void fill. They are also unsuitable for sending several products in the same package. For example, if you want to ship a t-shirt, wallet, and bottle of lotion, it&#;s probably better to use a box. Lumpy dimensions can make the mailers hard to scan en route, causing shipping delays.

What should I look for?

Here are some of the most important features to evaluate when comparing sustainable poly mailers:

Strength

Unlike corrugated shipping materials, there&#;s no &#;edge crush test&#; to measure the durability of poly mailers. Instead, you will have to consider the thickness of the mailer and the way it&#;s sealed. For maximum protection, look for products comprised of multiple layers with a secure seal on all three sides and a strong adhesive on the top.

Tear Strip

No matter what you&#;re shipping, you probably don&#;t want customers to mangle the packaging with a knife or box cutter to get to their items. With a precise tear strip, the bag can be easily opened.

Release Liner

The release liner protects the adhesive until you&#;re ready to seal the mailer. If you have to peel thousands of them, you want this step to be as easy&#;and static-free&#;as possible.

Bottom

While our eco-friendly poly mailers don&#;t have gusseted bottoms, the additional reinforcement can be helpful when shipping bulky or heavy items, like shoe boxes or thick quilts.

Dual Peel and Seal

A dual peel and seal is a double adhesive. That means the mailer has two release liners protecting two strips of adhesive. You can use the top strip for sending products out. Customers who want to make returns can then use the bottom one to seal the bag again before sending it back.

Tamper Evident

Some poly mailers have such a weak adhesive that you can peel and reseal it without leaving a trace. Our adhesive is strong enough to make our bags tamper-evident. If someone attempts to unseal it en route, the recipient will be able to tell. This helps mitigate missing and damaged items.

Size

You want your mailers to be large enough to fit your products easily but not so large that they have a lot of extra room or flimsy corners. The easiest way to choose the perfect size for every item is by ordering a host of samples and testing them individually. To help you get started, here&#;s a handy size chart with some generic dimensions.

SIZE CHART

How much do eco-friendly poly mailers cost?

Poly mailers are like any consumer product; you get what you pay for. That doesn&#;t mean, however, that you must buy the most expensive ones on the market to ensure your products make it safely to their destinations.

The cost of each mailer depends on several factors, including size, durability, materials, reusability, and eco-friendly features. Here&#;s a chart with a rough comparison of similar mailers from four companies.

COST CHART

When comparing prices, consider what your company stands for and what kind of impression you want to give customers. Durability also matters since items that are damaged en route will only cost you more in the long run. Put another way, getting a better quality shipping solution is often worth the extra 5 or 10 cents.
