A heat-shrinkable film comprising at least one gas barrier layer (A). The gas barrier layer (A) comprises a diamine component containing 70 mol% or more of metaxylylenediamine, 80 to 98 mol% of α, ω-linear aliphatic dicarboxylic acid having 4 to 20 carbon atoms, and 2 to 20 mol of isophthalic acid. It consists of a stretched film of a polyamide resin obtained from a dicarboxylic acid component containing%. Since the polyamide resin has an appropriate crystallization speed, whitening does not occur even if it is stretched at a low temperature, and a heat-shrinkable film having both high heat shrinkage and high transparency can be obtained. |
