Abstract

Process for the manufacture of biaxially stretched polyethylene of a thickness of 10 to 500 μm, characterized in that it comprises blow molding with a blowing ratio of up to 1: 10 a molding compound consisting of: (1) 100 parts by weight of a polyethylene obtained by a catalyst containing chromium (1.1.) having a density (1.2) of more than 0945 g/cm3 a melt index (1.3) (according to din 53 735 at 190º c/216 kg) below 10 g/10 min and a solution viscosity (1.4) (according to din 53 728/sheet 4) of 1 to 5 cm3/g (2) 005 to 1 parts by weight of a tris- (24-dialkylphenyl) -phosphite in wherein the alkyl groups are the same or different and in each case contain 1 to 9 carbon atoms and (3) - if appropriate - other traditional additives in customary amounts.
