DIN 53375 Plastic Film and Coating, Test for Determination of Coefficients of Friction

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DIN 53375 testing. This standard specifies a method for the determination of the coefficients of starting and sliding friction as the plastic film slides on itself or other materials.

Determination of adhesion and coefficient of friction is particularly important for film materials that are further processed on packaging and printing devices. Coefficients of friction indicate machinability and surface structure, which are important for printability.

The coefficients of adhesion and sliding friction on flexible foils can be simply measured in a static tester with an additional device. This standard test is defined in many standards.

The static friction force, as a rule, increases as the surfaces come into contact. Therefore, this time interval is specified in order to obtain comparable results.

Slip properties are sometimes created by additives in the plastic material. Additives have varying degrees of compatibility with the film matrix. They can bloom or infiltrate the surface and change the sliding properties. Because these effects are time dependent, measurements on such films should be related to the age of the film.
