Abstract
Tying tape-like materials formed by extrusion molding, comprising as a main component an aliphatic polyester having a melt viscosity of 1.0.times.10.sup.3 -4.0.times.10.sup.4 poises at a temperature of 190.degree. C. and a shear rate of 100 sec.sup.-1, and having a melting point of 70.degree.-190.degree. 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.
