Abstract
A multilayer structure includes a layer of a resin composition containing an ethylene-vinyl alcohol copolymer and a thermoplastic elastomer, wherein a mass ratio of the ethylene-vinyl alcohol copolymer to the thermoplastic elastomer is from 65/35 to 95/5 and the layer of the resin composition has one surface directly adjacent to a layer of polyolefin with no polar functional group. A multilayer structure is thus provided that is excellent in gas barrier properties, transparency, and flexibility and also has good delamination properties between the layer of the resin composition and the layer of the polyolefin with no polar functional group.
