PURPOSE: The titled sheet useful as a packing article slightly causing the whitening of ruling of processing at normal temperature, having improved welding properties at low temperature, obtained by adding a polyethylene having a fixed density and a propylene homopolymer to a propylene-ethylene random copolymer.
CONSTITUTION: (A) 30W80wt% propylene-ethylene random copolymer (preferably having a melt flow index of 0.3W10g/10min) having an ethylene content of ≤10wt%, preferably 2W5wt%, is blended with (B) 10W50wt% polyethylene (preferably MI of 0.2W5g/10min) having a density of ≥0.94g/cc and (C) 0W40wt% propylene homopolymer (preferably MI of 0.3W10g/10min) under heating. Ruling processing is carried out by using a type obtained by integrating a Thomson blade and a ruling blade to a veneer, and a sheet is pressed by pressure per length of ruling blade of 0.1W2ton/cm by a common machine press.
