ABSTRACT:
A high modulus, high strength coextruded polyolefin composite which can be drawn to higher draw ratios than single sheets of the polymers of which it is made is disclosed. It comprises a core layer of a polymer selected from the group consisting of polypropylene, polyethylene and linear low density polyethylene, and cap layers of a polymer selected from the group consisting of polybutylene homopolymers and copolymers with ethylene.
