Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a film for processing which can be molded at a low temperature and ensures the availability of a small molded product free from distortion due to printing. SOLUTION: The film for processing is made up of a biaxially orientated film consisting essentially of a polylactic acid. When the heat shrinkage rate in the longitudinal direction at 100°C of the film for processing is given as X% and the heat shrinkage rate in the crosswise direction is given as Y%, Y is 10% or lower and the heat shrinkage difference represented by an absolute value of the difference between X and Y is 5% or lower. In addition, the film for processing can be drawn at a temperature of 100≤ or lower. COPYRIGHT: (C)2003,JPO
