PROBLEM TO BE SOLVED: To provide a biodegradable film having biodegradable property that, during a period from seeding or planting of cultivation crops until the crops are grown to some extent, sufficient strength required in any films arranged in soil and on the soil surface is maintained, and at a timing after harvesting the cultivation crops and before start cultivating next crops, the film is degraded to an extent that there is no substantial problem in cultivation work.SOLUTION: There is provided a film made of a biodegradable resin composition. The biodegradable resin composition contains 47 mass% or more of an aliphatic-aromatic polyester resin relative to the total amount of resin components in the composition and at least one kind of triazine ultraviolet absorbing agents having absorptivity in a wavelength region of 250-400 nm.SELECTED DRAWING: None |
