ASTM D1894 Coefficient of Friction of Plastic Film
ASTM D1894 is a standardized test method 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. In order to ensure that they perform as expected for the end user, the frictional properties of these films must be characterized and controlled.
