摘要 |
PROBLEM TO BE SOLVED: To provide a polylactic acid-based film or sheet that has a tear strength such that the polylactic acid-based film or sheet does not break or tear when wound in the form of a roll or the like during manufacturing or processing of the film or sheet, and does not melt or deform even at high temperatures exceeding 100°C.SOLUTION: A polylactic acid-based film or sheet has: a tear strength of at least 100 N/mm when torn in at least the direction of flow (MD direction); a thermal rate of dimensional change that is within ±3% in both the direction of flow (MD direction) and the width direction (TD direction); and a thermal load rate of dimensional change that is within ±3% in the direction of flow (MD direction). |
