FILM OR SHEET HAVING EXCELLENT HEAT SEALABILITY

摘要

Heat-sealable films formed of a polybutylene terephthalate resin composition including between 50 to 95% by weight of a polybutylene terephthalate base resin having an intrinsic viscosity of 0.7 or greater, and between 5 to 50% by weight of a polycarbonate resin having an intrinsic viscosity of 0.4 or greater melt-blended with the polybutylene terephthalate base resin.
