Abstract
A multi-layer laminate structure comprises a separate layer of scrap produced from the several thermoplastic resins used in making the laminate structure. In a preferred construction, the multi-layer laminate structure comprises an outer thermoplastic polyolefin layer, an inner thermoplastic polyolefin layer and an intermediate oxygen barrier layer preferably made of ethylene-vinyl alcohol copolymer. An adhesive layer bonds the barrier layer to the inner polyolefin layer and a separate scrap layer is disposed interiorly of the outer polyolefin layer. A second adhesive layer bonds the scrap layer to the intermediate barrier layer. Containers having excellent oxygen barrier properties and good transparency are made by forming a parison from the multi-layer laminate structure and blow molding the parison to the desired container shape.
