Abstract
A degradable container which is excellent in transparency and impact strength and can be decomposed into nontoxic water and carbon dioxide in the natural environment within a relatively short period can be obtained by using the process for molding a container of an arbitrary shape from a thermoplastic composition having polylactic acid of lactic acids or a copolymer of lactic acids and other hydroxycarboxylic acids as a main component, preforming the composition and thereafter molding the container in a temperature range from Tg to Tg+60.degree. C. on the basis of the glass transition temperature Tg of the thermoplastic polymer composition and under the condition of a draw ratio of 6 times or less.
