Abstract
The present disclosure provides a polyolefin-based composition suitable for use as adhesives and/or tie-layer adhesive compositions as well as a multi-layered structure made from and/or containing the polyolefin-based composition. The polyolefin-based composition is made from and/or contains (a) a grafted polyolefin composition, (b) a first polymer composition, (c) a polypropylene-containing blend composition, and (d) optionally, an additives composition having one or more additives.
Claims3
A polyolefin-based composition comprising:
- (a) a polypropylene grafted with maleic anhydride;
- (b) a polymer composition comprising 10-90% by weight of a semicrystalline polypropylene having a crystallinity of more than about 30% by weight and less than about 70% by weight and 10-90% by weight of an ethylene propylene rubber copolymer comprising an ethylene content of about 20-65% by weight, based on the total weight of the ethylene propylene rubber.
