PURPOSE:To prepare the title film improved in blocking properties by compounding an ethylene copolymer resin contg. (meth)acrylic acid units, another polyolefin resin, and an inorg. powder and extruding the resulting compsn. CONSTITUTION:An ethylene copolymer resin contg. 3-15wt.% (meth)acrylic acid units, 1-20wt.% other polyolefin resin (e.g. a high-pressure low-density polyethylene), and 0.1-5wt.% inorg. powder having a mean particle diameter of 0.1-20mum (e.g. silica) are compounded and extruded into a film. The film has improved blocking properties while maintaining mechanical properties, heat sealability, transparency, water vapor barrier properties, and thermal fusion with metal or paper, and can be widely used as packaging and industrial materials. |
