ABSTRACT:
Extrusion-cast films of high molecular weight, linear, low density ethylene copolymers which inherently have high block and high cling characteristics are compounded with a minor amount of a low molecular weight organic, such as a polyglycol, before being extrusion-cast as a thin film, the low molecular weight organic serving to substantially reduce the block, but retaining high cling characteristics.
