How to Operate a Rolling Ball Tack Tester Efficiently

In the packaging industry, the use of pressure-sensitive tapes is very common. From commercial to domestic and industrial purposes, these tapes will offer you high quality in adhesion as per requirement. Thus, you can evaluate the adhesive strength of these pressure-sensitive tapes with the help of a rolling ball tack tester from Presto. This is very easy to operate testing equipment and has been designed in the compilation of various industrial standards. Here we are going to discuss brief information about rolling ball tack testers and how you can easily perform the test with some simple steps.

You will get efficient and thoughtful service from Cell Instruments.

What is a rolling ball tack tester?

The rolling ball tack tester from Presto Testing Instruments is one of the best-selling and easy-to-use testing equipment that lets you test the tack of adhesives. This testing instrument will quantify the ability of an adhesive to quickly adhere to another surface. The instrument is designed based on the balling method, and the primary adhesive property of adhesive tapes could be obtained by observing the adhesive effect that occurred immediately after the rolling ball and adhesive specimen come into contact. It works on a simple working principle where the steel ball is allowed to roll down from a specific starting point on the grooved path inclined at a specific angle to the base of the test platform. The rolling ball attains maximum velocity at touch down and rolls above the tacky surface which retards its motion by virtue of resistance offered by the adhesive.

This testing equipment has been embedded with several amazing features and appropriate technical specifications.

5 easy steps to operate rolling ball tack tester

To make sure that you get appropriate testing results from the rolling ball tack tester, you can follow the five easy steps mentioned below.

1. First, clean the mirror surface and paste the sample over there.
2. Now, paste the adhesive tape over the Mirror surface in such a way so that the adhesive part is on the upper side.
3. Put the SS Ball in the ball putting fixture area.
4. Then move the knob upwards.
5. Measure the traveling distance of the ball over the sample with help of T in reference to the steel scale.

These are five easy steps you can follow in order to operate this testing instrument efficiently. Whenever you are going to use this testing instrument, then you should make sure that there will be no inflammable material placed near the equipment. You should properly put the test specimen on the test fixture. In this way, you can test the sample accurately with the help of this lab testing instrument. You can also view our different paper and package testing instruments like peel/seal bond adhesion tester, peel strength tester, etc.

Loop tack of adhesive tape is measured by testing the force required to separate the loop adhesive tape (adhesive side facing outwards) from the test plate. Look tack is one basic index of adhesive tape both in China and many European countries and USA.

According to Method A specified in GB/T -: Test Method of Adhesive Tape: Loop Tack, Labthink&#;s auto tensile tester can be used to test loop tack of adhesive tape with assistance of customized test plate for loop tack test. Labthink&#;s XLW series auto tensile testers and MED-01 Medical Packaging Tester can be used to test loop tack of adhesive tape accurately and quickly.

T-shaped stain-less steel test plate for loop tack test is installed in the lower sample grips of the tensile tester. Two free ends of the adhesive tape specimen (24mm wide, adhesive surface facing outwards) is clamped in the upper sample grips. Then start the tensile tester. The upper sample grips will move downward at speed of 300mm/min until the central part of loop specimen adhesive tape contact with the central area (24mm by 24mm) of the T-shaped test plate. 3 seconds later, the upper sample grips will move upward at the same speed.

The test result will be the maximum force which causes the separation of loop specimen from the test plate. One more thing is that the user should observe in which way the loop specimen separates from the test plate so as to analyze the defects in manufacturing of adhesive tapes.

Labthink also supports customization of sample grips for FINAT Method: No.9 loop tack test.

Based on experience, loop tack test method has better data repeatability and is more applicable to tack testing of self-adhesive labels and similar adhesive materials. The advantages of tack test method by rolling ball include simple testing operation and low price of testing instrument, which is applicable to quick and simple tests in manufacturing site or laboratory.
