PROBLEM TO BE SOLVED: To provide a laminate for coextrusion based on a cografted polyolefin mixture and a polyolefin / binder / polyamide, EVOH, polyester or metal. Useful in manufacturing packaging materials. SOLUTION: Polyethylene or ethylene copolymer (A) and a polypropylene or propylene copolymer (B 1), a mixture with at least one kind of (B) selected from poly (1-butene) homopolymer or copolymer (B2) and polystyrene homopolymer or copolymer (B3). , A mixture of (A) and (B) is grafted with a functional monomer, and the grafted mixture of (A) and (B) is optionally mixed with at least one polyolefin (C) and at least one It is diluted with a rubber-elastic polymer (D) or a mixture of (C) and (D). Preferably, the functional monomer is maleic anhydride. |
