ABSTRACT:
Disclosed is a cross-linked heat shrinkable film comprising an ethylene polymer resin which has a gel fraction of 5-40%. Furthermore, this film contains a glycerin fatty acid ester surface active agent in an amount of 2.0-8.0% by weight based on the total weight of the ethylene polymer resin, said surface active agent being present in an amount of 3.0-20.0 mg/m2on at least one surface of the film. This film has characteristics adaptable to speeding-up of continuous packaging machines, namely, a proper coefficient of dynamic friction and hot tack sealability, with maintaining appearance of the film after being shrunk, such as heat shrink characteristics, fog resistance and gloss.
