Title:
MULTILAYER STRUCTURE, RESIN COMPOSITION FOR ADHESIVE RESIN LAYERS, AND METHOD FOR PRODUCING MULTILAYER STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/021149
Kind Code:
A1
Abstract:
A multilayer structure which comprises an adhesive resin layer between a thermoplastic resin layer and a gas barrier resin layer, and wherein: the adhesive resin layer is formed from a resin composition for adhesive resin layers containing (A) a polyolefin resin containing at least one of a carboxyl group and an acid anhydride group and (B) a fatty acid zinc salt; and the fatty acid zinc salt (B) is contained in an amount of 40 to 250 ppm in terms of metals relative to the adhesive resin layer. Consequently, this multilayer structure is greatly suppressed in interface roughening that occurs at the lamination interface between the base barrier layer and the adhesive resin layer, thereby having excellent transparency at a high level.
