Sliding friction is an important property to consider when selecting packaging films. The coefficient of sliding friction (COF) is a measure of the force required to move one surface in relation to another and is a good indicator of how easily the film will slide over itself or other surfaces. Thus, testing the quality of these films is very important to make sure that the right products will be delivered to the customers with ease. We at Presto have come up with one of the amazing lab testing instruments known as the coefficient of friction tester. The digital model of this lab testing instrument indicates the starting and sliding friction of plastic films and sheets when slide over each other at a specified test condition. Here we will discuss how you can easily determine the co-efficient value of plastic films with the use of the Presto friction tester. So, let us get started!
What is the coefficient of friction tester and its uses in the plastic film industry?
In the plastic film manufacturing industry, the coefficient of friction is vital for determining product quality. When two surfaces slide against each other, the friction between them can cause wear and tear, or even jamming. By testing the coefficient of friction, manufacturers can ensure that their products will perform as expected under real-world conditions.
When manufacturers conduct co-efficient friction test using the Presto COF tester, then they will be able to get accurate testing results for sliding friction. The main purpose of using this testing equipment is to measure the stackability of plastic films. The value that will depend on friction will depend on both the load (pressure or perpendicular force applied) as well as the velocity.
Uses of COF tester in the plastic film manufacturing industry
As we have discussed above, the COF tester used in the manufacturing industry will help you determine the surface properties of materials like plastic or flexible films, sheets, etc. This testing instrument will also measure the static as well as kinetic friction of the materials with ease. This test can be conducted under specified load testing conditions that will help you to measure static as well as kinetic friction of plastic films.
This high-quality and standardized lab testing instrument can be widely used in the packaging industry as well to determine the coefficient of friction value of materials like plastic films, paper, etc. When you determine the stacking ability of plastic films then your package materials will easily be stacked over each other without getting slide over each other.
Thus, this
testing instrument will prevent further accidents from happening during the transportation or storage of products. You can read more about the

Now, let us focus on the features and technical specifications of this testing equipment.
Features of Co-efficient of friction tester
This lab testing instrument will help you to strictly determine the value of the coefficient of friction of different materials with ease. If the value of sliding friction will be lower then, that means the surface will be slicker and is less resistant to sliding motion. Below we have listed the features of the co-efficient of friction tester:
- Clamps are provided to attach samples to the glass slab.
- Safety switches are provided at the end surface to stop the motion of the load cell along with the weight.
- Gives both dynamic and static friction.
- Speed regulating knob.
- Digital display for both kinetic and dynamic friction.
- Calibrated in accordance with ISO norms, Calibration Certificate provided traceable to (NABL).
