Abstract
Claims
1. A biaxially oriented film comprising polylactic acid and amorphous polyester, wherein the content of polylactic acid is 50% by mass or more and 89% by mass or less per 100% by mass of the biaxially oriented film, and the content of amorphous polyester is 11% by mass or more and less than 20% by mass per 100% by mass of the biaxially oriented film.
2. The biaxially oriented film according to claim 1, wherein the content of amorphous polyester relative to 100% by mass of the biaxially oriented film is 11% by mass or more and 19% by mass or less.
3. The biaxially oriented film according to claim 1, wherein the amorphous polyester is an amorphous aliphatic polyester.
4. The biaxially oriented film according to claim 3, wherein the amorphous polyester is an amorphous polyhydroxyalkanoate.
5. The biaxially oriented film according to claim 1, wherein the content of polylactic acid relative to 100% by mass of the biaxially oriented film is 75% by mass or more and 89% by mass or less.
6. The biaxially oriented film according to claim 1, wherein the modulus of elasticity in the MD direction is 5.0 GPa or less, and the modulus of elasticity in the TD direction is 5.0 GPa or less.
7. The biaxially oriented film according to claim 1, wherein the heat-sealing strength is 10.0 N / 15 mm or more.
8. The biaxially oriented film according to claim 1, wherein the haze is 8.0% or less.
9. A biaxially oriented film according to any one of claims 1 to 8, having a thickness of 10 μm or more.
10. A film comprising a biaxially oriented film according to any one of claims 1 to 8.
