MOLDED OBJECT OBTAINED THROUGH STRETCHING AND THERMAL FIXING AND PROCESS FOR PRODUCING THE SAME

摘要

A molding which is formed from a hydroxyalkanoate resin consisting mainly of polylactic acid by stretch forming and thermal fixing,characterized in that in large−angle X−ray diffraction analysis the molding gives,in the 2θrange of 10 to 25°,a diffraction peak having a half band width(X)of 1.220°or smaller,especially 1.100°or smaller.The molding is excellent in transparency and heat resistance although it is made of a biodegradable plastic.The stretched form,especially container,is useful as a container for beverages.
