POLYETHYLENE COMPOSITION AND MANUFACTURING METHOD BY THE SAME, AND THE FILM CONTAINING THE POLYETHYLENE COMPOSITION

摘要

PURPOSE: A polyethylene resin composition for a film is provided to ensure excellent tear strength, transparency, and film processability and to obtain a film for packaging objects without the damage of the film. CONSTITUTION: A polyethylene resin composition for a film comprises (a) linear low-density polyethylene containing 5~13 weight% butane-1 in which a melt index is 0.8~1.5g /10 minute, density is 0.917~0.924 g/cm^3, molecular weight distribution is 4~9, and (the number of average short branches)/(1000 carbons) is 10~25 when weight molecular weight is 50,000~500,000; (b) low density polyethylene prepared by a high-pressure tubular process in which a melt index is 2~4 g/10 minute, density is 0.918~0.928 g/cm^3, and distribution of molecular weight is 4~9; and (c) aluminosilicate dehydrate in which average particle size is 3.5~4.5 micron and bulk density is 0.4~0.6 g/ml.
