POLYMER FILM AND MANUFACTURE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polymeric film good in antistatic properties, printability, heat sealability and laminating processability and useful as a packing film and other industrial film. SOLUTION: A polymeric film is formed by laminating a first polymeric resin layer containing 65-95wt.% of a polyester resin containing 0.01-0.1wt.% of metal sulfonate, 0.005-0.5wt.% of a phenolic compd. having steric hindrance and 1-20wt.% of an inorg. lubricant and 5-35wt.% of a polyolefin resin with a melt flow index of 1.0-25g/10min to a second polymeric resin layer containing a polyester copolymer containing ethylene terephthalate and ethylene isophthalate as main repeating units.
