<p><P>PROBLEM TO BE SOLVED: To provide a polyamide laminated biaxial stretched film which is effective for preventing dropping destruction of a large heavy bag for business use or the like, and is suited to various packages. <P>SOLUTION: A polyamide mixed resin laminated film is formed by stacking a layer B consisting of an aliphatic polyamide polymer and a m-xylylene based polyamide polymer or a mixed polyamide polymer prepared by adding thermoplastic elastomer on at least one surface of a layer A consisting of a mixed polymer of an aliphatic polyamide polymer, thermoplastic elastomer, and/or an aliphatic copolymer polyamide polymer, and stacking an adhesive altered layer formed by applying a specific amount of copolymer polyester on one surface of the layer B that becomes an outermost layer. Impact strength is &ge;0.7 J, sticking strength is &ge;10 N, a static friction coefficient at 23&deg;C, 65 %RH is &le;0.90, the number of bent pinhole defects at a low temperature is &le;5 pieces, and laminate strength in a specific environment is specific value or above. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT</p> |
