Abstract
Disclosed is a laminate structure adapted for use as a retortable packaging material, comprising:
(I) a layer of polyalkylene terephthalate or polycarbonate resin, (III) a saponified olefin/vinyl acetate copolymer layer, and (II) interposed therebetween, a layer of an adhesive resin composition. The adhesive resin composition comprises 100 wt. parts of a soft polymer and 1-30 wt. parts of polyethylene partially or wholly graft modified with unsaturated carboxylic acid or its derivative. The soft polymer may be styrene elastomer alone or in combination with ethylene/.alpha.-olefin copolymer and/or ethylene/vinyl acetate copolymer. Interlaminar peeling of the laminate rarely occurs even under a high temperature filling or retort treatment.
