PROBLEM TO BE SOLVED: To provide a composition reduced in hardness and improved in physical properties by adding and mixing a PET-G resin with a TPEE resin, and a soft film and a zipper for a plastic zipper bag produced from the mixture.SOLUTION: The problem is solved by obtaining a soft PET-G resin composition by extrusion-molding a mixture including a TPEE resin of 10 to 140 pts. to 100 pts.wt. of a PRT-G resin. Also, the problem is solved by a soft film and a zipper for a zipper bag obtained by extrusion-molding the mixture. Preferably, the soft PET-G resin composition, and the soft film and the zipper for a zipper bag are composed as the one additionally mixed vegetable oil by 5 to 90 pts.wt. with the PET-G resin as 100 pts.wt.SELECTED DRAWING: Figure 1a |
