<p><P>PROBLEM TO BE SOLVED: To obtain a resin composition which improves the various physical properties of a polyethylene terephthelate (PET) resin and its processability into inflation films, has a higher strength than that of a polyolefin film, and has a low film heat-sealing temperature similar to that of a polyolefin, to provide a method for forming a film from the resin composition, and to provide a film heat-sealed product. <P>SOLUTION: This polyethylene terephthalate resin composition comprises 60 to 80 wt. % polyethylene terephthalate resin, 1 to 10 wt. % of an ethylene-glycidyl (meth)acrylate copolymer and/or an ethylene-glycidyl (meth)acrylate-lower alkyl (meth)acrylate terpolymer, and 10 to 35 wt. % of a low density polyethylene resin. The method for using a film comprises using the resin composition by an inflation method. The polyethylene terephthalate resin composition film product is produced by heat-sealing the film produced from the resin composition at a temperature of≤200°C. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
