POLYAMIDE RESIN COMPOSITION FOR INNER LAYER OF DELAMINATION CONTAINER, AND DELAMINATION CONTAINER OBTAINED USING SAME

摘要

A polyamide resin composition for the inner layer of a delamination container which comprises at least two superposed layers comprising an outer layer (1) constituted of a thermoplastic resin (A) and an inner layer (2) that is constituted of a polyamide resin composition and is capable of separating from the outer layer (1) and deforming to decrease in volume and in which the outer layer (1) has, formed therein, outside air introduction holes for introducing the outside air into between the outer layer (1) and the inner layer (2), the polyamide resin composition comprising a specific polyamide resin (a) and a specific polyamide resin (b), having a tensile modulus, as measured at a temperature of 23ºC and a humidity of 50% RH, of 2,000 MPa or less, and having a content of the polyamide resin (a) of 20-75 mass%; and a delamination container obtained using the polyamide resin composition as the inner layer.
