Abstract: An object of the present invention is to provide a coated paper that includes a coating layer containing poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) with few coating defects. As a solution, the present invention provides a coated paper including a coating layer containing poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) and an adhesive, on at least one side of a paper substrate. A solid content weight ratio of the poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) to the adhesive in the coating layer is 99.9/0.1 to 60.0/40.0.

Abstract: Provided is a resin sheet for thermoforming, the resin sheet containing a poly(3-hydroxybutyrate) resin. A difference between a melting point peak temperature and a melting point peak end temperature in differential scanning calorimetry analysis of the poly(3-hydroxybutyrate) resin is 10° C. or more. The sheet has a thickness of 0.15 to 1 mm. The melt viscosity of the poly(3-hydroxybutyrate) resin at 160° C. is preferably 10000 poise or more.

Abstract: Provided are a resin composition containing poly(3-hydroxyalkanoate), the resin composition enabling a film or a sheet to be stably produced under practical processing conditions by inflation molding; and a method for producing the resin composition. The resin composition includes 100 parts by weight of poly(3-hydroxyalkanoate) and 5 to 15 parts by weight of an ester compound, and having a ratio of 3.5×10−2 to 4.8×10−2 (sec/[Pa·s]) between a melt viscosity (Pa·s) and a drawdown time (sec).
