ABSTRACT:
A process for preparing a retort-proof laminate for packaging foodstuffs which comprises laminating an aluminum substrate to at least one polyolefin film selected from the group consisting of high density-polyethylene, polypropylene, ethylene-propylene copolymers and polybutene films using as an adhesive a specific polyolefin resin in melted state prepared by combining together (A) at least one member selected from the group consisting of high-density polyethylene, polypropylene ethylene-propylene copolymers and polybutene, (B) maleic anhydride and (C) aluminum hydroxide, and by rendering said specific polyolefin resin substantially free from unreacted maleic anhydride and low molecular weight maleic anhydide homopolymers.
The process also includes preparing a retort-proof coated aluminum substrate for packaging foodstuffs which comprises coating an aluminum substrate with a layer formed from the above-described specific polyolefin resin and thereafter forming a suitable retort packaging container therefrom.
