ASTM D1894 and ISO 8295: Coefficient of Friction on Plastic Film

To ensure that plastic films perform as expected for the end user, the frictional properties of these films must be characterized and controlled.

ASTM D1894 and ISO 8295 are standardized test methods used for determining static (μ_s) and kinetic (μ_k) coefficients of friction of plastic film and sheeting. Plastic film is a widely used material in the packaging industry and includes many types of food packaging (produce bags, carton liners, meat seal wrap) and non-food packaging (envelope liners, potting soil sacks). Plastic films are also key components of more complex products, such as electric vehicle batteries.

This test requires the use of Instron's 2810-005 coefficient of friction fixture, which is specifically designed to meet the requirements of ASTM D1894 and ISO 8295. The film under test is secured on a flat surface, and a sled of known weight is wrapped in the same material. The motion of the crosshead drags the sled along the film being tested, and the force measured is used to determine both the static and kinetic coefficients of friction.
