Abstract: A resin film is laminated thereon a gas barrier layer having gas barrier properties to constitute a laminate for a packaging body. The resin film contains polyethylene terephthalate. In a cross section of the resin film, the softening temperature of the resin film in the width direction and the softening temperature thereof in the flow direction measured by local thermal analysis are in the range of 200° C. or more and 254° C. or less.

Abstract: A production method including: a step of forming, on a substrate layer containing a polypropylene resin or a polyester resin, a metal oxide layer by a vacuum film forming process; a step of applying a gas barrier coating layer-forming composition on the metal oxide layer to form a coating film; a step of preheating the coating film by infrared radiation; and a step of heating and thereby curing the coating film preheated by infrared radiation in an atmosphere at 50 to 120° C. to form a gas barrier coating layer, in which the gas barrier coating layer-forming composition contains at least one selected from the group consisting of an alkyl silicon alkoxide and its hydrolysate, and a water-soluble polymer.
