Biaxially oriented polyamide resin film |
| 摘要 |
<p>The present invention provides a biaxially oriented polyamide resin film strong and superior in resistance to pinhole, laminating property and appearance, which is free of curling or peeling of laminated films (delamination) when subjected to boiling water treatment and which has superior properties as a packing material, particularly, a packing bag for retort-packed food. <??>The biaxially oriented polyamide resin film simultaneously satisfies the following formulas (1) and (2): 3%</=BSx</=6% (1) wherein Bsx is the maximum boiling water shrinkage proportion among the boiling water shrinkage proportions measured in all directions, BSa</=1.5% (2) wherein BSa is an absolute value of the difference between the boiling water shrinkage proportion in the direction forming an angle of +45 DEG with the travel direction of the film, and that in the direction forming an angle of -45 DEG therewith, and is obtainable by transverse drawing using a tenter and heat-setting.</p> |
