摘要：
A process for the manufacture of a polymer film comprising:
obtaining a polymer composition comprising at least 70% wt of a chromium HDPE and 3 to 30% wt of a unimodal mLLDPE;
extruding and then blowing said film at blow up ratio of 2:1 to 4:1
so as to obtain a film having a tensile strain at break in the transverse direction of at least 550%.
