<p>A heat-shrinkable film comprising at least one gas-barrier layer (A). The gas-barrier layer (A) is constituted of a stretched film of a polyamide resin obtained from a diamine ingredient comprising at least 70 mol% m-xylylenediamine and a dicarboxylic acid ingredient comprising 80-98 mol% linear aliphatic a,?-dicarboxylic acid having 4-20 carbon atoms and 2-20 mol% isophthalic acid. The polyamide resin has a moderate rate of crystallization, and hence suffers no blushing even when stretched at a low temperature. A heat-shrinkable film combining a high degree of thermal shrinkage with high transparency can be obtained therefrom.</p> |
