Title:
MULTILAYER BLOW-MOLDED CONTAINER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2006/107099
Kind Code:
A1
Abstract:
Disclosed is a multilayer blow-molded container having a layered structure wherein a polyglycolic acid layer serves as a core layer and a thermoplastic polyester resin layer is arranged on both sides of the polyglycolic acid layer. A polyglycolic acid used for forming the polyglycolic acid layer has a melt viscosity x of 300-900 Pa·s as measured at a shear rate of 122 sec-1 and at a temperature of 270&ring C, while a thermoplastic polyester resin used for forming the thermoplastic polyester resin layer has a melt viscosity y of 250-600 Pa·s as measured at a shear rate of 122 sec-1 and at a temperature of 290&ring C. The melt viscosity ratio x/y between the two is from 0.85 to 1.80. Also disclosed is a method for producing such a multilayer blow-molded container.
