Abstract: Provided is a resin film containing a reaction product of 100 parts by weight of a poly(3-hydroxyalkanoate) resin component and 0.01 to 0.5 parts by weight of an organic peroxide. The poly(3-hydroxyalkanoate) resin component includes: a copolymer (A) which is a copolymer of 3-hydroxybutyrate units and 3-hydroxyhexanoate units and in which a content of the 3-hydroxyhexanoate units is from 1 to 6 mol %; and a copolymer (B) which is a copolymer of 3-hydroxybutyrate units and 3-hydroxyhexanoate units and in which a content of the 3-hydroxyhexanoate units is 24 mol % or more.

Abstract: A multilayer film includes a first resin layer and a second resin layer. Each of the first and second resin layers contains a poly(3-hydroxyalkanoate) resin. The ratio of the thickness of the first resin layer to the thickness of the second resin layer is from 1.0:0.015 to 1.0:5.0. A heat quantity ΔH of the first resin layer is 30 J/g or more, and a heat quantity ΔH of the second resin layer is 25 J/g or less. The heat quantity ΔH of each of the first and second resin layers is heat of melting over a temperature range of 130 to 190° C.
