POLYLACTIC ACID-BASED MULTILAYERED SHEET FOR THERMO-FORMING, AND ITS FORMED BODY

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid-based multilayered sheet for thermo-forming which shows excellent forming workability and gives a formed body having a thermal resistance and a shock resistance. SOLUTION: The polylactic acid-based multilayered sheet for thermo-forming has one layer composed of a polylactic acid-based polymer as a major component, stretched and thermo-fixed and the other layer composed of a polylactic acid-based polymer having a melting point by 2°C or more lower than that of the polylactic acid-based polymer of the one layer. The tensile strength of the polylactic acid-based multilayered sheet is 2 to 30 kg/cm2at 135°C. COPYRIGHT: (C)2008,JPO&INPIT
