Abstract: An object of the present invention is to provide a multilayer stretched polyamide-based film having excellent bending resistance, thermal dimensional stability and aroma retention, whose lamination strength is measureable when a sealing layer is laminated thereon. Specifically, the invention provides a multilayer stretched polyamide-based film obtained by biaxially stretching a multilayer laminate including three layers consisting of a polyester layer (Layer A), an adhesive layer (Layer B), and a polyamide layer (Layer C), wherein Layer A contains a crystalline polyester, Layer B contains a modified polyester-based elastomer, Layer C contains an aliphatic polyamide, and Layer C has a thickness of 5 ?m or more, and wherein a sealing layer is to be laminated on Layer C by a lamination method, after biaxially stretching the multilayer laminate.

Abstract: An object of the invention is to provide a multilayer stretched film with barrier property that is free from deterioration of barrier properties attributable to dimensional change caused by moisture absorption, and bending, etc. [Method for Achieving the Object] A multilayer stretched film with barrier property obtained by biaxially stretching a multilayer laminate comprising at least three layers, namely, a polyester-based resin layer (Layer A), a polyamide-based resin layer (Layer B), and a polyester-based resin layer (Layer A), in this order (wherein the two Layers A may be the same or different) to obtain a biaxially stretched multilayer film; and providing a deposition layer (Layer C) on at least one surface of the biaxially stretched multilayer film; both of the Layers A containing a crystalline polyester; Layer B containing 70 to 99 wt % of aliphatic polyamide and 1 to 30 wt % of aromatic polyamide; and Layer C containing an inorganic substance.
