Document Type and Number:
Japanese Patent JP3745061
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To produce a film and a layer having relatively high rigidity and strengths, improved transparency, and high gloss.
SOLUTION: This single- or multiple-layer film contains at least one molded polyolefin composition derived from at least 2C olefin represented by the formula: Ra-CH=CH-Rb (wherein Ra and Rb, which may be the same or different from each other, are each hydrogen or a linear or branched 1-15C alkyl, provided that they may form together with the atoms to which they are bonded a ring or a ring system) and produced by using a metallocene catalyst. A molded polyolefin composition having a particle diameter of 20-5,000μm is used or prepared. This and at least one additive are melt-mixed and molded. The material prepared by the melt mixing and molding is melted at 150-300°C, and the molten material is simultaneously cooled and molded to obtain a film or a layer.
