PROBLEM TO BE SOLVED: To provide a packaging material which is tolerant toward various contents and excellent in boiling resistance. SOLUTION: In the packaging material, a barrier layer, an adhesive layer, and a sealant layer are stacked in turn. The adhesive layer contains an acidified polyolefin resin (A) and a crosslinking agent (B), wherein the mass ratio (A/B) of (A) to (B) is 99.9/0.1-50/50, (A) contains 0.1-10 mass% of an unsaturated carboxylic acid component, and (B) is a polyvalent oxazoline compound (b1) and/or a polyvalent hydrazide compound (b2).

Abstract:
The present invention relates to an adhesive resin for expansion sheet using mutually reactive copolymers and an expansion sheet using the same. Particularly, the present invention provides an adhesive resin having excellent adhesive strength on a substrate before expansion and excellent upholding power for microsphere to inhibit expansion and a heat-peelable adhesive sheet that is easily separated from the substrate when adhesive strength is lost by heat treatment at high temperature. The adhesive resin prepared by mixing mutually reactive copolymers has advantages of long-term shelf-life since cross-linking does not occur at room temperature, maintaining upholding power of the expansion layer during the production of a heat-peelable adhesive sheet, and increasing expansion temperature of microsphere so that it facilitates easy separation from a substrate when the substrate is heated at high temperature owing to the reduced or lost adhesive strength thereafter.
