Abstract
A laminate includes a fabric; and a thermoplastic film, wherein the thermoplastic film is a multilayer film including an adhesive layer including a thermoplastic polyester elastomer and a barrier layer that is bonded to the adhesive layer, and that has a melting point that is higher than a melting point of the adhesive layer, and that includes a polymer, and wherein the fabric includes a polyester, and the fabric has a fabric weight of 190 g/m2 or less.
Claims5
An airbag formed using a laminate, the laminate comprising:
- a fabric;
- and
- a thermoplastic film, wherein
- the thermoplastic film is a multilayer film including
- an adhesive layer including a thermoplastic polyester elastomer;
- and
- a barrier layer that includes a thermoplastic polyester elastomer, wherein the thermoplastic polyester elastomer included in the barrier layer has a melting point that is higher than a melting point of the adhesive layer, and the barrier layer being bonded to the adhesive layer,
- the adhesive layer is a plurality of layers,
- the thermoplastic polyester elastomer included in the adhesive and the barrier layers comprises soft segments and hard segments, wherein a content of soft segments in the thermoplastic polyester elastomer included in the barrier layer is 5 wt % to 60 wt % relative to the total weight of the thermoplastic polyester elastomer in the barrier layer,
- the fabric includes a polyester, and
- the fabric has a fabric weight of 190 g/m2 or less, wherein
- the fabric is formed to have a shape of a bag, and
- the multilayer film is formed on a surface of the fabric.
