What is The Loop Tack Test and for What Purpose It is used

The pressure-sensitive adhesives are usually applied to films, labels, tapes, and other related materials. According to ASTM D, it is important to take a loop tack test of the materials in order to assure their quality. Thus, we at Presto Testing Instruments have come up with one of the amazing labs known as peel adhesion/bond/seal strength tester computerized model to quantify the permanence of adhesion or peel ability of self-adhesive pressure-sensitive materials. This advanced testing machine can easily be used in different industries like adhesive tapes, double-sided tapes, and so forth.

Here in this article, we are going to provide you with brief information about peel tester and for what purpose the loop tack test will be conducted. So, let us get started!

Introduction about peel/seal/bond adhesion tester

Tack is an essential property of a material that is usually measured as the force required for breaking the adhesive bond between two surfaces. Thus, the peel adhesion bond tester will help you to study the adhesion properties of various self-adhesive materials. This instrument is meant for creating high forces that will further be used for testing and analysis purposes. The outer body of the machine was made duly powder coated and comes with the digital peak load indicator for digital readout of test results.

This high-tech lab testing instrument has been fabricated with mild steel and has been provided with the best safety features that prevent the clashing of grips. We have listed the features of the computerized model of this lab testing equipment below.

Key features of peel/seal/bond adhesion tester (digital cum computerized model)

The loop tack test will be conducted to measure the tack of adhesive tapes that have been formed into a loop. Presto peel/seal/bond adhesion tester comes with the adhesive testing properties and provides you the accurate testing results for debonding of adhesives from the surface. Below we have created a list of its features.

Now, let us focus on the purpose of performing the loop tack test.

The main purpose of performing loop tack test

Tack is considered to be the property of a material to test how quickly the bond will be formed when it is brought in contact with a surface with very slight pressure. In the packaging industry, with the vast use of adhesives, it is important for the manufacturers to perform the peel test to make test whether the adhesive materials will be influenced by the external force or not. This test will be conducted from different angles. Thus, you can easily perform a 180-degree peel test or 90 degrees to test the quality of materials.

The tack of the material will depend on different factors that are related to the typical roughness of the surface along with temperature and processing conditions. With the help of this lab testing equipment, you will be able to test the tack adhesiveness of materials and make sure that the product will be relevant. The loop tack tests are intended for quality control and test the ability of pressure-sensitive materials to create a bond for products. If you wish to test the adhesiveness of the pressure-sensitive materials then you can give us a call at +91 or us at . Our technical team of experts will consult you regarding your queries.

Standard Method for Loop Tack Test

Loop Tack Test is one method to measure the tack strength of adhesive tapes and pressure sensitive adhesives. ASTM D describes a method (using tensile Tester) to make use of a specimen strip 7 in. (175 mm) in length. Both the FINAT FTM 9 &#;Quick Stick&#; Tack Measurement Test and the TLMI L-IB2 Tensile Tester Loop Tack Test also use a specimen strip of that length.

Another method is to use a single purpose machine, Loop Tack Tester, while it is uncommonly the sole test of any manufacturer.

If you have a Tensile Testing Machine or universal Testing Machine, you can also perform many other common adhesive and material tests such as 90 degree peel adhesion tests, 180 degree peel adhesion tests, and standard tensile strength testing.
