ABSTRACT:
A laminate, which has improved resistance to the passage of oil therethrough and which is suitable for the packaging of oleaginous substances, particularly motor oil, is described. The laminate comprises a pair of outer layers of a solid ethylene polymer, such as polyethylene or copolymers of ethylene with propylene or butene-1, and at least one inner barrier layer of a dried emulsion coating of a vinylidene chloride copolymer, the inner barrier layer being bonded to the inner surfaces of the outer layers. One of the outer layers may be bonded to the inner barrier layer by means of an oil-resistant adhesive, or, in the case where there are two inner barrier layers, the inner layers may be bonded together by an oil-resistant adhesive between the dried emulsion coatings.
