Abstract

A blend of at least three different polyethylene-based components is described which can be extrusion coated onto a substrate to give a strong bond therewith with short curing times. The blend comprises a medium density polyethylene with a narrow molecular weight distribution, a low density polyethylene homopolymer with a broad molecular weight distribution, and a linear low density polyethylene copolymer.
