A biodegradable laminated article includes: a substrate layer; a first thermoplastic resin (A1) layer located on one side of the substrate layer and containing a polyhydroxyalkanoate resin; and a second thermoplastic resin (A2) layer located on the other side of the substrate layer and containing a polyhydroxyalkanoate resin. The weight per unit area of the first thermoplastic resin (A1) layer is from 10 to 200 g/m, and the weight per unit area of the second thermoplastic resin (A2) layer is from 0.1 to 5 g/m.

Biodegradable laminated article and method for producing the same

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.

Coated paper

An adhesive resin composition, including: a base resin which comprises (A) 30-90 parts by weight of a modified ethylene-olefin copolymer, and (B) 70-10 parts by weight of a styrene thermoplastic elastomer, provided that (A)+(B) equals 100 parts by weight; and (C) a tackifier in an amount of 30-60 parts by weight per 100 parts by weight of the base resin, the modified ethylene-olefin copolymer being one which has been graft-modified with (a) an unsaturated carboxylic acid or a derivative thereof and (b) an aromatic vinyl monomer, comprises 0.1%-5% by weight of (a) the unsaturated carboxylic acid or the derivative thereof, and has a melting point peak in a range of 100-150&#xb0; C. with an enthalpy of crystal fusion of 0.5-10 J/g as determined by DSC.
