Polyester tying tape-like materials

摘要

Tying tape-like materials formed by extrusion molding, comprising as a main component an aliphatic polyester having a melt viscosity of 1.0x103-4.0x104 poises at a temperature of 190 DEG C. and a shear rate of 100 sec-1, and having a melting point of 70 DEG -190 DEG C. The present invention provides tying tape-like materials excellent in heat stability, mechanical strength and packing property as well as having biodegradability which can be used as packing materials.
