STRETCHED RESIN FILM AND PROCESS FOR PRODUCING THE SAME

摘要

A stretched resin film which is a monoaxially stretched film comprising 70 to 94 wt.% propylene polymer (A), 3 to 30 wt.% polybutene-1 (B), and 3 to 30 wt.% petroleum resin (C) and/or hydrogenated terpene resin (D). This film has high transparency and high stretching-direction rigidity, and has such excellent properties that it shrinks little during product storage but has a large shrinkage upon heating.
