Abstract:
Extrusion-cast films of high molecular weight, linear low density ethylene copolymers which inherently have high block and low slip characteristics are compounded with a minor amount of a secondary fatty acid amide and a finely-divided natural inorganic, e. g. , silica, before being extrusion-cast as a thin film, the additives serving to substantially reduce the block and increase the slip characteristics of the film.
