Abstract: Provided is a poly(3-hydroxybutyrate) resin tube including a poly(3-hydroxybutyrate) resin, the tube having a wall thickness of 0.1 to 0.6 mm. The difference between the melting point peak temperature and the melting point peak end temperature in differential scanning calorimetry analysis of the poly(3-hydroxybutyrate) resin is preferably 10° C. or higher. Preferably, production of the tube includes the step of melting a poly(3-hydroxybutyrate) resin in an extruder, then extruding the resin from an annular die, and introducing the resin into water, the annular die temperature being set to a temperature between the melting point peak temperature and the melting point peak end temperature in differential scanning calorimetry analysis of the poly(3-hydroxybutyrate) resin.

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.
