ABSTRACT:
The present invention discloses a resin composition containing 26.about.70 weight % of thermoplastic polyester resin, 10.about.30 weight % of polyester elastomer, and 20.about.44 weight % of vinylidene chloride resin and a biaxially stretched heat shrinkable film having cold resistance and oxygen gas barrier property comprising said resin composition, and further a biaxially stretched heat shrinkable laminated film having not only oxygen gas barrier property and cold resistance, but also melt hole resistance, heat resistance sealing property, and transparency after the shrinkage and comprising barrier layer of said resin composition, outer layer (polyamide or crosslinkable polyolefin), inner layer (crosslinkable polyolefin), and heat sealable layer (low crosslinkable polyolefin), at least the outer layer, the inner layer and the heat sealing layer being crosslinked by electron beam irradiation.
