ABSTRACT:
It has now been found that certain properties including peel seal characteristics of wrapping films or sheets may be improved by fabricating films or sheets from blends of high molecular weight butene-1 homopolymers or copolymers, and low density polyethylene (either modified or non-modified) and wherein such films or sheets can be bonded to a substrate such as aluminum foil, by coextrusion or lamination, with or without a tie layer adhesive forming novel structures.
