Exploring the Unique Characteristics of High Shrink PET-G ...

Polyethylene terephthalate glycol films, or PET-G films, are clear, highly durable, and transparent plastic films made from Polyester (PET) resin that has been modified using Glycol and, hence, the name PET-G.

The PET-G films market has been witnessing significant growth and was valued at USD 397 million in and is anticipated to reach USD 737.5 million by . This growth is the result of increasing demand for sustainable packaging solutions across various industries.

Let's read this blog below and learn about the characteristics of high-shrink PET-G films.

Characteristics of High Shrink PETG Films

1. Excellent Shrinkability : PET-G films are high-shrink polyester films with uniform shrinkage. When exposed to heat, the film can shrink up to a predetermined percentage. The high shrinkability allows the PET-G film to conform tightly to the product's shape, providing a snug and tamper-evident seal.
2. Enhanced Transparency : These polyester films are transparent and allow for the packaged product to be easily visible. This is beneficial in retail applications as it allows for an easy view of the product, as product appearance is one of the essential selling points.
3. Highly Durable : PET-G films provide enhanced protection against environmental factors like dust and moisture. These films offer excellent protection during product transportation and storage.
4. Superior Printability : Our PET-G films deliver superior printability and do not show any fisheyes, which occurs due to the molten material present in the film.
5. Versatile : PET-G films can be used for products such as food, beverages, pharmaceuticals, customer goods, and more.
6. Heat-Sealable : Polyethylene terephthalate glycol films are heat sealable films. These films shrink and tightly adhere to the product, creating a secure and tamper-resistant seal.
7. Branding & Labelling : These printing films can be printed with high-quality logos, graphics, and product information. This helps with the effective branding and labeling of packaged products.
8. Recyclable : PET-G films by Cosmo Films are recyclable and considered environment friendly compared to other Shrink Films.

The PETG Shrink film is suitable for all kinds of printing technologies from ROTOGRAVURE to FLEXO PRESS using solvent based to UV cured ink. HYF,as a environmentally friendly shrink film factory, we offer PETG shrink film for shaped bottles, PETG high shrinkage film for bottle sleeves, PETG shrink film with high shrinkage, PETG high shrink films, here we shows you the pros and cons of petg material.

Advantages

Polyethylene terephthalate offers a number of advantages over other substances, including acrylics and polycarbonates. These advantages include:

1. Strong and cost effective

PETG's strength and impact resistance means it is ideal for glass and high-strength display devices. It is also ideal for 3D printed products, displays and signage. 2.

2. Food safe and recyclable

PETG shrink film is safe for use in food containers and beverage bottles. It is also fully recyclable, which reduces waste and potential negative environmental impact. 

3. Easy to Form

PETG can be both vacuum-formed and thermoformed and can withstand high pressures without cracking. It can be molded into various shapes or extruded into sheets.

4. Easy to colorize

PETG is naturally transparent and can produce unique effects, but it can also be easily colored and mixed to create different looks.

5. Non-Toxic and Odorless Emissions

PETG is non-toxic and odorless during the 3D printing process, making it ideal for home and office use.

Disadvantages

There are few disadvantages to using polyethylene terephthalate, but care still needs to be taken, especially with temperature parameters.

1. Parameters to follow

When 3D printing PETG, it is recommended to use the correct temperature parameters. It is recommended that you follow the parameters set by each material manufacturer, which are usually 210-260 ºC for the extruder and 60-80 ºC for the base material, although a cold base can also be used. It is also recommended to use low print speeds (30 - 35 mm/sec) while achieving optimal values for the 3D printer.

2. Easy bleed

PETG is more prone to bleed than PLA or ABS, which means you will need to experiment with bridging and retraction settings during the 3D printing process. Therefore, additional post-processing may be required to remove any imperfections.

3. Improper storage can become brittle

PETG can absorb water if not stored in a dry environment, which can make the part more brittle.

4. Environmental Issues

As with all plastics, PETG can have a potentially negative impact on the environment if not handled properly. It can take decades to break down and cause microplastics to enter the world's oceans. PETG, however, is easily recycled, eliminating these environmental concerns.

Production Method

PETG is produced using a two-step melt-phase polycondensation process. This relatively simple process joins two different monomers together while releasing a small molecule, such as water.

PETG can be injection molded, sheet extruded, or extruded into fine filaments for 3D printing. This clear, amorphous thermoplastic can also be colored during processing.

The Future of PTEG

As the global market continues to grow, the future of polyethylene terephthalate looks bright, although there is still a need to ensure that used PETG materials are recycled.

Conclusion

Polyethylene terephthalate is a versatile and versatile plastic with many properties that outperform similar materials. With the growing popularity of 3D printing applications, PETG is also widely used in the food and medical industries.
