Packaging films are widely used in the packaging industry to protect products from damage during shipping and storage. These films will act as a barrier against damage that occurs to the products due to rough handling. These films have their own features and properties that make them the top choice for most product packaging companies. 

Many packaging film manufacturers have higher quality standards in order to keep up with customer demands for high-value products, which include a non-slip or anti-static surface. Therefore, it is important to test the sliding friction of these films by conducting a COF test. To make it easy for packaging product manufacturers to conduct a co-efficient of friction test, we at Presto have designed one of the amazing lab testing instruments known as the coefficient of friction tester. This highly advanced lab testing equipment will efficiently indicate the sliding friction of plastic films and sheets when sliding over a surface. Here, we will discuss a brief about Presto's co-efficient of friction tester and how you can easily perform packaging film tests on the materials with ease.

What is a Coefficient of Friction Tester?

Packaging films are an important part of the packaging industry and come in a variety of types and applications. There are two main types of packaging films: stretch films and non-stretch films. Stretch films are made from a very thin sheet of plastic that is heated and then stretched until it becomes very thin. This allows products to be packed in tight spaces without damaging them and makes them flexible enough to conform to different shapes. Non-stretch films are made from a thicker sheet of plastic that is not heated and does not stretch. These films are used for products that do not need to be flexible, such as tablets or cereal boxes.
Testing these plastic packaging films, against the coefficient of friction, is an important part of the quality control process. Thus, with the use of the Presto coefficient of friction testing instrument, you will be able to measure the static coefficient of friction between two surfaces by applying constant pressure. The test results are used to determine if a surface is suitable for packaging materials. This testing instrument plays a significant role in the paper and packaging industry.
The COF tester digital model designed by experts at Presto will help plastic film manufacturers to conduct the COF test on the materials with ease. It comes with slider blocks for performing the COF tests and helps to view the display for dynamic and kinetic friction force. The fly screws will be used with no slippage of the specimen and are tightened uniformly using fly screws performed without any loops.
Its feather touch controls will make it easy for the users to operate this lab testing equipment with ease. Besides this, it has been equipped with high-quality features that we have listed below.
