Flexible Packaging Film Coefficient of Friction Tester COF Testing – GBPI

Coefficient of Friction Tester for Flexible Packaging

The Coefficient of Friction Tester is used to test the coefficient of friction of plastic film, thin sheet, paper and other flexible packaging materials. This equipment measures both the static (initial) and kinetic (moving) coefficients of friction (COF), which determines the smoothness and opening difficulty of the film.

Product Features

– Core parts are imported, with high performance, stability and accuracy

What is the coefficient of friction?

The coefficient of friction (COF) is a measure of the frictional force between two surfaces. There are two kinds of COF: static (the force needed to begin movement) and kinetic (the force required to maintain movement).

Why is COF important in packaging?

COF provides a relative indication of frictional characteristics in substrates such as plastic films. Controlling COF gives processors the ability to optimize performance and avoid problems in forming, transporting, and storing of packages.
