PURPOSE:To provide the title compsn. having excellent transparency, squeezability, resistance to environmental stress cracking and heat and ultrasonic sealability, consisting of a specified branched low-density, PE, a linear low- density PE and a high-density PE. CONSTITUTION:90-50pts.wt. branched low-density PE having an MI of 0.2-10g/10min and a density of 0.915-0.930g/cm<3> is melt-mixed with 5-25pts.wt. linear low-density PE having an MI of 0.2-5g/10min, a density of 0.915-0.935g/cm<3> and a flow ratio of 15-70, 5-25pts.wt. high-density PE having an MI of 0.2-5g/10min, a density of 0.94-0.96g/cm<3> and a flow ratio of 15-150 and optionally, an antioxidant, an ultraviolet absorber, an antistatic agent, a lubricant, etc., at 120-280 deg.C. The mixture is pelletized. |
