3 simple steps to prepare a sample for the COF test

3 simple steps to prepare a sample for the COF test

When two surfaces come into contact and slide against one another, a variety of microscopic interactions will occur between them that may result in friction and wear. These interactions can cause a variety of problems in the plastics sector throughout the manufacturing and shipping processes.

Friction can cause damage to the plastic materials, making them more brittle and less able to withstand the stresses of shipping and handling. In addition, friction can also generate heat, which can lead to warping and deformation of the plastic parts. Thus, testing the friction of packaging films is of utmost importance to make sure that your packaging material will not slide against each other easily. This will help to protect the package during shipping, storage, or transportation. We at Presto have come up with one of the efficient testing instruments known as the coefficient of friction tester which is helpful in testing the sliding friction of plastic films and sheets. Here we will discuss how you can easily conduct the sliding friction test for packaging materials by preparing the sample accurately. But first, let’s focus on the use of Presto co-efficient of friction testing instrument in the packaging industry. So, let us get started!

Easily evaluate the sliding friction of packaging films with Presto COF tester

When it comes to packaging products, it is important to be aware of the static and dynamic friction of the materials being used. By understanding how these forces work, you can take steps to reduce the risk of damage to your products during shipping and handling. Static friction is the force that resists the initial motion of an object. This force becomes increasingly strong as the object will move faster. On the other hand, dynamic friction is the force that resists the motion of an object once it is already in motion. This force decreases as the object moves faster. By testing for static and dynamic friction, you can find the optimal packaging material for your products. Thus, you can easily make use of Presto Static and dynamic friction tester to get highly accurate results for co-efficient of friction test. 
By understanding friction, you can take control of your packaging and ensure that your products arrive safely at their destination. You can easily assess the friction of rolls with the use of Presto co-efficient of friction tester.
Presto kinetic friction tester is a steady device that shows the beginning and sliding contact of plastic sheets and films. You can even control the frictional properties of packaging films with the use of Presto co-efficient of friction tester. Below we have listed the features and technical specifications of this lab testing instrument

Thus, we have accumulated 3 easy ways through which you can easily prepare the sample for the friction test.

Simple and easy to follow steps to prepare a sample for the COF test

The coefficient of friction tester is an accurate lab testing instrument that can be used to determine the stackability of plastic films. The tester works by measuring the force required to slide one film over another. By knowing the coefficient of friction, you can determine how well two films will interact with each other. This information is useful in a variety of applications, such as packaging and printing. The tester is easy to use and provides accurate results. With the help of this instrument, you can ensure that your plastic films will stack correctly and perform as expected.
Whenever you conduct COF tests then you need to prepare the sample first. You can easily do this by following the steps mentioned below.
  • Take the plastic sheet as a sample and cut it with the dimensions of 53x15x1 mm.
  • Place the sample over a glass sheet.
  • The glass sheet will provide full support to the specimen.
In this way, you can accurately prepare the specimen for performing the COF test. By testing the friction value of packaging films, you can easily improve your product quality.
