摘要:
A multilayer film is provided that includes a) a barrier layer including a thermoplastic polyester elastomer or a polyamide copolymer; b) an intermediate layer provided on the barrier layer and including a maleic anhydride (MAH)-grafted polyolefin and an α-olefin copolymer; and c) an adhesive layer provided on the intermediate layer and including a thermoplastic polyester elastomer or a polyamide copolymer. The multilayer film enables production of gas-tight multilayer laminates which exhibit an excellent peel resistance combined with a low weight and/or thickness. Further, a multilayer laminate and an inflatable airbag that include a fabric layer adhered to the multilayer film, as well as methods of manufacturing are described.
