PROBLEM TO BE SOLVED: To prepare the subject film markedly improved in antifogging sustainability, excellent in transparency, with no mould growth during use, and useful for e.g. agricultural greenhouses, by incorporating a lactic acid-based polymer film with a specified amount of lubricant, etc. SOLUTION: This film is prepared by incorporating (A) 100 pts.wt. of a lactic acid-based polymer with (B) 0.1-0.2 pts.wt. of a lubricant and/or (C) 0.1-5 pts.wt. of an antiblocking agent and (D) 0.1-5 pts.wt. of an antifogging agent. It is preferable that the component B is at least one kind of compound selected from the group consisting of fatty acid-based lubricant and fatty acid amide- based lubricant, the component C is silica, and this film is such one as to be at least uniaxially oriented by a factor of 1.3-10 and is 0.01-2mm in thickness. |
