PROBLEM TO BE SOLVED: To provide a film mainly composed of biodegradable resin and having excellent shape retention and degradable properties.SOLUTION: A film comprises a biodegradable resin (A). When a thickness of the film is T(μm) and a Young's modulus in a direction in which the Young's modulus becomes largest (direction a) is Ea(GPa), Ea×Tis 1,000 GPa/μmor more and 60,000 GPa/μmor less, and a weight thereof is 10 g/mor more and 50 g/mor less.SELECTED DRAWING: None |
