Abstract:
An L-lactic acid polymer molded product prepared by heat treating at 40-65.degree. C. and successive molding a L-lactic acid polymer composition comprising 100 parts by weight of a mixture consisting essentially of 80-95% by weight of an L-lactic acid polymer having an L-lactic acid proportion of 75% or more and 5-20% by weight of a plasticizer selected from the group consisting of a polyhydric alcohol ester and a hydroxypolycarboxylic acid ester wherein said percentages of L-lactic acid polymer and plasticizer are based on the total amount of L-lactic acid polymer and plasticizer, 0.1-5 parts by weight of an antiblocking agent having a SiO.sub.2 content of 90% or more and an average particle size of 7-50 nm, and 0.1-2 parts by weight of a slip agent, the parts by weight of the antiblocking agent and the slip agent being based on 100 parts by weight of the mixture.
