SOLUTION: The opening of the package includes a layer for a reclosable function. The layer constituted of a base material with at least one part comprising a resin composition containing an acrylic liquid polymer (A) with a number average molecular weight of 1,000-100,000 and a hydroxy value of 10-1,000 and an isocyanate curing agent (B). The amount of isocyanate curing agent is preferably equivalent to that where the amount of isocyanate groups is 0.5 mol-2.0 mol for 1 mol of hydroxy groups contained in the acrylic liquid polymer.
