POLYETHYLENE TEREPHTHALATE RESIN COMPOSITION AND MOLDED ARTICLES USING SAME

摘要

Provided are: a polyethylene terephthalate resin composition that is suitable for zippers and closure caps, said resin composition having good heat sealing properties, excellent flexibility and sealability, and the ability to easily be formed into a single film; and molded articles, such as films, zippers and closure caps, that use said resin composition. The resin composition comprises, with respect to 100 parts by mass of polyethylene terephthalate, 0.1 to 3 parts by mass of a styrene-methyl (meth)acrylate-glycidyl methacrylate copolymer, 3 to 20 parts by mass of a softener, and 0.05 to 1.5 parts by mass of a molding aid. The molded articles are obtained by using the resin composition.
