CPP film is cast polypropylene that is manufactured by an extrusion process of a molten polypropylene web through a slot die onto a revolving cast chill roll. This roller may be mirror finished for smooth films or surface textured for embossed films.
The resulting films vary in thickness which makes CPP film ideal for a range of polymer applications. For example, typical thickness ranges for American Profol’s CPP films are from 1 mil to 12 mils. Single wound sheeting with widths available up to 102”.
