    摘要: The present invention provides a polyamide based mixed resin laminated film roll formed by winding up a polyamide based mixed resin laminated film comprising a plurality of polyamide mixed resin sheets stacked on top of each other. A first sample cutout portion is provided within 2 m from the winding end of film, and a final sample cutout portion is provided within 2 m from the winding start of film. The roll is regulated so that, when sample cutout portions are provided at intervals of about 100 m from the first sample cutout portion, for all samples cutout from the cutout portions, the elastomer content, tensile modulus of elasticity, thickness unevenness in the longitudinal direction and other properties fall within a predetermined variation range.

    摘要: A polyester stretch film having good tear property and good twistability, which is useful as a packaging film or a film for tape, as well as for stick packaging, PTP packaging, drug bag, folding packaging, and lid material is provided without losing heat resistance, cold resistance, moisture-proof properties, transparency, aroma retention and the like. This polyester resin film is produced by a method that includes mixing not less than two kinds of polyester resin starting materials having different melting points and extruding the mixture. The respective starting materials are cast in different extruders, melted, supplied to one mixer in a molten state, mixed and extruded to give a sheet, and the sheet is stretched at least in the monoaxial direction and heat-treated at a temperature of not lower than 3° C. lower than the melting point of the resin starting material having the lowest melting point.
