Want to Prepare a Sample for a COF Tester?

If you are looking to evaluate the stacking strength of the packages that are wrapped with plastic films, you need to perform the coefficient of friction test. This is one of the best tests that help you evaluate the sliding friction of plastic sheets when they are stacked above the product with plastic film or any other substance during warehousing or transportation.

In plastic film manufacturing industries, every manufacturer wants to avoid friction between the packaging products to avoid any damage. For example, if two laminated packages are slippery in nature, they will easily slip down from the storage if they are stacked one above the other that can lead to fall or burst.

Therefore, it is mandatory for the manufacturers to keep a strict eye on measuring the sliding friction of packaging materials so as to keep them protected from getting damaged. In this blog, we will provide you information regarding how you can use the Coefficient of Friction Tester, and prepare the sample accurately in your testing machine.

Before that, primarily we will discuss the main purpose of using the coefficient of friction tester.

Purpose of COF Tester

In packaging industries, the manufacturers evaluate the quality of plastic films and test the friction in them. The plastic films and laminates having more slipperiness leads to damage during storage and transportation. Therefore, it is very important for you to test the stacking friction of laminated packages so as to improve the quality of the packaging products and avoid products from damaging.

The COF or coefficient of friction is measured by rubbing the two surfaces against each other. When the product has low friction, then the surface is more slicker which means there is less resistance to the sliding motion.

Using the Coefficient of friction testing instrument you can easily measure the frictional strength in plastic films. The testing instrument will be performed by sliding the block onto a plastic film on the plane surface that evaluates the coefficient of frictional force between the block and the plane.

Let’s now discuss how to prepare the sample to perform the test using Coefficient of Friction Tester

Step-by-Step Process to Prepare the Sample for COF Test

Coefficient of Friction COF Tester is a static testing machine that helps you measure the stackability of plastic films. If you want to prepare your test sample to perform the test, follow the below-mentioned steps:

1. Cut the sheet according to the size of the glass plane approximately 53 x 15 x 1mm.
2. Now place the sample right over the glass sheet.
3. This provides a smooth support to the test specimen.
4. Now attach the sample to the block as well.
5. Your sample is now ready to perform the test.

By testing the coefficient of friction of laminated products, you can easily enhance the quality of the packagings.
