POLYLACTIC ACID-BASED RESIN SHEET AND MOLDED ARTICLE FORMED OF ITS SHEET

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid-based resin sheet which exhibits a suitable anti-fogging effect even in packaging foods and a molded article formed of the sheet. SOLUTION: The polylactic acid-based resin sheet is obtained by coating a sucrose fatty acid ester on the surface of a sheet base material molded from a resin mixture obtained by mixing a monoglycerin fatty acid ester with a polylactic acid-based resin. The monoglycerin fatty acid ester is composed of an ester of an 8-22C aliphatic monocarboxylic acid and monoglycerin, and the resin mixture is obtained by mixing 0.5-3 pts.wt. monoglycerin fatty acid ester with 100 pts.wt. polylactic acid-based resin. The sucrose fatty acid ester has an HLB value of not less than 13 and is coated on the sheet base material in an amount of 20-50 mg/m2. COPYRIGHT: (C)2009,JPO&INPIT
