1. A method of manufacturing a laminate including a fabric that includes a polyester, and a thermoplastic film, the thermoplastic film being a multilayer film that includes an adhesive layer including a thermoplastic polyester elastomer; and a barrier layer that is bonded to the adhesive layer, the barrier layer having a melting point higher than a melting point of the adhesive layer, and including a thermoplastic polyester polymer, the method comprising:
adhering a side of the multilayer film with the adhesive layer to the fabric, while heating the multilayer film at a temperature in a range that is greater than 200° C. and less than or equal to 250° C., wherein
the thermoplastic polyester elastomer included in the adhesive layer is a block copolymer including a soft segment including a polyether and a hard segment including a polyester, and
each of the adhesive layer and the barrier layer are melted and then the adhesive layer and the barrier layer are extruded and molded simultaneously by coextrusion.
