摘要: A thermoplastic polymer composition primarily comprising polylactic acid or a copolymer of lactic acids and the other hydroxycarboxylic acids than lactic acids, industrial fabrics which can be degraded into nontoxic water and carbon dioxide within a relatively short period under the natural environment, and flexible containers, water shielding sheets and resin coated-cloth ventilation tubes which are prepared from the industrial fabrics.
