    摘要: The invention provides a carbon neutral heat-sealable layered film that is excellent in heat resistance, impact resistance, and bending pinhole resistance. The layered film has at least a base material layer and a sealant layer, wherein the base material layer is a biaxially stretched polyamide film in which a layer B is laminated on at least one surface of a layer A, the layer A contains 70%-99% by mass of a polyamide 6 resin, and 1%-30% by mass of a polyamide resin containing a raw material derived from biomass, the layer B contains 70%-100% by mass of a polyamide 6 resin, the sealant layer is an unstretched polyolefin film, and the unstretched polyolefin film contains 70%-95% by mass of a polypropylene-based resin, and 5%-30% by mass of a linear low-density polyethylene resin in which at least a part of a raw material thereof is derived from biomass.
