Abstract
Provided are a multilayer body including a polyolefin resin layer containing a xylylenediamine-based polyamide resin and a barrier layer; a packaging material; and a method for producing a packaging material. A multilayer body includes: a polyolefin resin layer (A) containing an acid-unmodified polyolefin resin as a main component; and a barrier layer (B) containing a barrier resin as a main component. The polyolefin resin layer (A) contains from 0.1 to 8 mass% of a xylylenediamine-based polyamide resin and from 0.1 to 15 mass% of an acid-modified polyolefin resin. The xylylenediamine-based polyamide resin is a polyamide resin containing a diamine-derived structural unit and a dicarboxylic acid-derived structural unit, 70 mol% or more of the diamine-derived structural unit being derived from a xylylenediamine, and 70 mol% or more of the dicarboxylic acid-derived structural unit being derived from an α,ω-linear aliphatic dicarboxylic acid having from 4 to 20 carbon atoms.
