Packaging films serve as a critical component in ensuring the protection and preservation of products during storage and transportation. To guarantee their effectiveness, it is essential to subject these films to rigorous testing procedures, including the friction test. Thus, to make it easy for the packaging manufacturers to conduct the COF test on the packaging films, we at Testronix Testing Instruments have designed a high-quality co-efficient of friction tester. The computerized model of friction tester has been designed to determine the COF value of flexible packaging films and ensure that quality products will be delivered to the customers.

Here, we will discuss briefly how you can easily measure the frictional properties of packaging films with the help of a computerized COF tester. We will also discuss a brief about the role of friction testing in the packaging film industry.

Role of friction testing of packaging films

Friction is a force that resists the relative motion of two surfaces in contact. The amount of friction between two surfaces depends on the nature of the materials, the surface roughness, and the amount of pressure between the surfaces.

In packaging film, friction is an important consideration because it can affect the seal quality, printability, and runnability of the film. The coefficient of friction (COF) is a measure of the frictional force between two surfaces. The higher the COF, the greater the frictional force and vice versa. Thus, testing the frictional properties of these films will serve you with the following advantages:

  • It will help to optimize your packaging process.

  • By testing these properties, packaging designers can select the most appropriate materials to ensure smooth and efficient packaging processes.

  • Testing frictional properties ensures that the heat-sealing equipment applies the right amount of pressure and heat to achieve consistent and reliable seal integrity.

  • Frictional properties impact the wear and tear that packaging materials undergo during handling, transportation, and storage. By selecting films with appropriate friction levels, companies can minimize abrasion and damage to the packaging, maintaining its aesthetic appeal and functional integrity.

  • Proper testing allows manufacturers to choose materials that protect the product's surface and appearance during all stages of the supply chain.

These are some of the advantages one will get by testing the frictional properties of packaging films. You can achieve optimal quality packaging films by testing the frictional properties of these packaging materials.

Now, let us discuss a brief about Testronix co-efficient of friction tester and how it can be helpful in testing the frictional properties of packaging films.

Now, let us discuss how you can easily measure the frictional properties of packaging materials efficiently.

How to measure the frictional properties of packaging materials efficiently?

Testing the CoF films of the material is one of the essential properties of the material that makes it easy for the manufacturers to ensure that their packaging materials will not slide when stacked over each other.

To conduct the test using the co-efficient of friction tester computerized model, you can follow the steps mentioned below:

  • Prepare the testing sample and place it on a glass sheet. This provides smooth support for the testing specimen.

  • Tighten the sample across the glass slab with the help of fly screws attached at the corner.

  • The sample should be placed straight on the mounting surface without any loops/ Wrinkle free.

  • Take the slide block to the extreme left using the toggle switch.

  • Now attach the test block to the slide block with the help of a string in such a manner that the load cell must not touch the fly clamp.

  • After following all the above steps, you can easily commence the test.
