Abstract
PURPOSE:The titled composition, prepared by incorporating low-density polyethylene, etc. and a lubricant in an ethylene-alpha-olefin copolymer without reducing the toughness, etc., and suitable for a thin inflation film usable as a transparent food packaging material. CONSTITUTION:A composition prepared by kneading 70-95wt% copolymer (hereinafter referred to as a base material) of ethylenic polymer or a copolymer of ethylene with a 3-12C alpha-olefin having an MI <=0.5g/10mm., a density >=0.940g/cc and a ratio (HLMI/MI) <=40 with 5-30wt% low-density polyethylene, etc. having a lower melting point than the base material, good compatibility with the base material and a refractive index close to that of the base material and a lubricant, e.g. an alkaline metallic salt of a higher fatty acid, in an amount of 0.1-3pts.wt. based on 100pts.wt. sum of both components. The composition has a density >=0.940g/cc, an MI <=0.5g/10mm., an HLMI/MI <=60, a melt tension >=5g, a haze <=15% and a film impact >=150kg-cm/mm..
