Abstract

A process for preparing a retort- proof laminate for packing foodstuffs which comprises laminating an aluminum foil or sheet with 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 an aluminum ion-crosslinked polyolefin resin in melted state prepared by reacting together (A) at least one member selected from the group consisting of a high- density polyethylene, polypropylene, ethylene-propylene copolymers and polybutene, (B) maleic anhydride and (C) aluminum hydroxide.
