LAMINATE, PACKAGING MATERIAL USING LAMINATE, AND PRODUCTION METHOD FOR LAMINATE

摘要

The present invention addresses the problem of providing a laminate that has sufficient delamination prevention capacity and that also has an inorganic layer that is imparted with a brilliant sheen. The laminate according to the present invention has, in order, a polyolefin resin layer, a vapor-deposited layer, and an inorganic layer. The vapor-deposited layer includes a vapor-deposited layer composition (P) and polypropylene (D). The vapor-deposited layer composition (P) is obtained by melting and kneading 30-85 wt% of isotactic polypropylene (A) and 15-70 wt% of a propylene copolymer (B). All or part of the isotactic polypropylene (A) and/or the propylene copolymer (B) is graft modified with a graft monomer (C). The propylene copolymer (B) includes 45-89 mol% of a propylene-derived structural unit and 11-55 mol% of a structural unit that is derived from at least one type of α-olefin selected from among ethylene and an α-olefin that has 4-20 carbon atoms.
