<p>A heat-shrinkable film and a heat-shrinkable multi-layer film which are prepared from a resin composition which comprises an aromatic vinyl compound-conjugated diene block copolymer having a microphase separated structure comprising a soft phase and a hard phase and further having a specific structure and preferably exhibiting a specific dynamic viscoelasticity spectrum and a styrene polymer having a syndiotactic structure, in a specific ratio. The heat-shrinkable film or a heat- shrinkable multi-layer film offers an excellent balance of heat resistance, high shrinkability especially at a low temperature, the resistance to natural shrinking, chemical resistance and rigidity.</p> |
