Abstract: A laminate includes a paper substrate layer and a first resin layer located on at least one side of the paper substrate layer. The first resin layer contains a poly(3-hydroxybutyrate) resin and polyvinyl alcohol having a degree of saponification of less than 90 mol %. The solids weight ratio of the poly(3-hydroxybutyrate) resin to the polyvinyl alcohol is from 99.8/0.2 to 95.0/5.0. The laminate can be produced by applying an aqueous coating liquid to at least one side of the paper substrate and drying the applied aqueous coating liquid to form the first resin layer on the paper substrate.

Abstract: An object is to provide (I) a PHA powder which has (i) good redispersibility when the PHA powder is formed into a slurry and (ii) good film forming properties when the PHA powder is applied to slurry coating and (II) a method for producing the PHA powder. The object is attained by providing a PHA powder in which a composition ratio of a 3-hydroxybutyrate unit to a 3-hydroxyhexanoate unit is 80/20 to 91/9 (mol/mol), a moisture content is not more than 20%, and a circularity of a primary particle present at a surface of the PHA powder is not less than 0.92.
