Method of manufacturing laminate, laminate, and airbag

A laminate comprising:

• a fabric that includes a polyester;
• and
• a thermoplastic film, the thermoplastic film being a multilayer film including
• an adhesive layer including a thermoplastic polyester elastomer;
• and
• a barrier layer that is bonded to the adhesive layer, that has a melting point that is higher than a melting point of the adhesive layer, and that includes a thermoplastic polyester polymer, 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,
• a side of the multilayer film with the adhesive layer is adhered to the fabric, while heating the multilayer film at a temperature in a range of from 120° C. to 250° C., 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.

An airbag comprising:

• a laminate including:
• 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, wherein
• a side of the multilayer film with the adhesive layer is adhered to the fabric, while heating the multilayer film at a temperature in a range of from 120° C. to 250° C., and while pressurizing to 18 N/cm2,
• 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
• the thermoplastic film is made by melting each of the adhesive layer and the barrier layer, and then extruding and molding the melted adhesive layer and the melted barrier layer simultaneously by coextrusion.
