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

摘要

The present invention addresses the problem of providing a laminate having sufficient delamination prevention performance and simultaneously having an inorganic layer surface imparted with brightness. The laminate of the present invention is a laminate having a polyolef in-based resin layer, a layer for deposition and an inorganic layer in this order, wherein the layer for deposition includes a composition (P) for a layer for deposition and polypropylene (D), the composition (P) for a layer for deposition is obtained by melt-kneading 30 to 85% by weight of isotactic polypropylene (A) and 70 to 15% by weight of a propylene-based copolymer (B), a part or all of the isotactic polypropylene (A) and/or the propylene-based copolymer (B) has been graft-modified with a graft monomer (C), and the propylene-based copolymer (B) contains 45 to 89% by mol of constituent units derived from propylene and 11 to 55% by mol of constituent units derived from at least one ±-olefin selected from ethylene and ±-olefins of 4 to 20 carbon atoms.
