polylactic acid-based resin foam sheet, and method for producing a polylactic acid-based resin foam sheet

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid-based resin foam sheet excellent in strength and thermal resistance and capable of being thermally molded easily; and to provide a production method suitable for producing the polylactic acid-based resin foam sheet.;SOLUTION: This invention relates to the polylactic acid-based resin foam sheet used for being thermally molded, wherein a polylactic acid-based resin with which a center portion in a sheet thickness direction is formed is lower in crystallinity than a polylactic acid-based resin with which a surface layer portion is formed.;COPYRIGHT: (C)2013,JPO&INPIT
