Determination of the Coefficients of Friction (COF) of Films
ISO 8295, ASTM D1894, JIS K 7125, DIN 53375Among other things, the coefficient of friction (COF) provides information about the surface structure and printability of plastic films. The static and dynamic coefficient of friction is particularly interesting for films that are further processed on packaging and printing machines.

Determination of the static and dynamic coefficient of friction is particularly interesting for films that are further processed on packaging and printing machines. Coefficients of friction provide information about the processability and the surface structure, which is important for determining the printability of the material.
The static and dynamic coefficient of friction for flexible films can be easily measured on a static testing machine with an additional fixture. This standard test is defined in many standards.
