<p>PURPOSE:The titled composition having low change with extrusion during molding, and balanced low-temperature heat sealability rigidity, etc., obtained by blending individually specific crystalline propylene polymer, low-density ethylene polymer and low-density polyethylene. CONSTITUTION:(A) A crystalline propylene polymer (e.g., propylene-ethylene copolymer, etc.) having 0.1-20g/10min melt flow rate is blended with (B) a low- density ethylene polymer having 0.910-0.935g/cm<3> density and 2-10wt% monomer content prepared by using a Ziegler catalyst, and (C) a low-density polyethylene having 0.910-0.935g/cm<3> density, 0.5-20g/10min melt flow rate, and 1.2-2.3 memory effect, prepared by high-pressure method. 100pts.wt. total amounts of 30-80pts.wt. component A and 70-20pts.wt. component B are blended with 2-20pts.wt. component C.</p> |
