PROBLEM TO BE SOLVED: To provide a roll-shaped material of a polylactic acid-based film without forming "sag" or "lump". SOLUTION: This roll-shaped material of the polylactic acid-based film has≤2.0 Rz, roughness by averaging 10 points, and the surface hardness of the roll-shaped material obtained by rolling the polylactic acid-based film is within 86-95 degree range measured by a C-type rubber hardness meter based on the Japanese industrial standard JIS K7312. Here, the average thickness of the polylactic acid-based film is preferably within 7-80μm range. COPYRIGHT: (C)2004,JPO&NCIPI |
