Abstract: A coated polymeric multilayer article including: (i) a polymer substrate including (a) a first polyolefin-based layer including a primary ethylene-based polymer; and (b) an adhesion layer on at least one surface of the first polyolefin-based layer including one or more secondary ethylene-based polymers selected from secondary polyethylene homopolymers, secondary ethylene-based copolymers of ethylene with one or more C3-C10 alpha olefin monomers or ethylene-vinyl acetate (EVA) copolymer; and (ii) a coating layer on at least one surface of the adhesion layer. A method of producing a coated polymeric multilayer article, the method including the steps of: forming a polymer substrate including a first polyolefin-based layer and an adhesion layer on at least one surface of the polyolefin-based layer; and applying a coating layer composition on at least one surface of the adhesion layer.

Abstract: A polymer composition may include a plurality of ethylene-based polymers forming a multimodal composition distribution, each having a distinct crystallization peak in a CEF curve. A process of making a polymer composition may include melt blending a plurality of polyethylenes with different microstructural characteristics in the molten state. Another process of making a polymer composition may include polymerizing ethylene and an optional alpha olefin in combination with a plurality of metallocene catalysts in a polymerization reactor to form a plurality of ethylene based polymers. Yet another process of making a polymer composition may include polymerizing ethylene and an optional alpha olefin in combination with a multimetal catalyst in a polymerization process to form a plurality of ethylene based polymers.
