A biodegradable laminate, wherein a polyvinyl alcohol resin layer is laminated on at least one surface of an aliphatic polyester resin layer through an adhesive layer, which is excellent in biodegradability and gas barrier properties, and also excellent in interlayer adhesiveness, is obtained. The adhesive layer comprises, as a main component, a polyester resin (A') which has a polar group and is obtained by graft polymerization of an &#x3b1;,&#x3b2;-unsaturated carboxylic acid or an anhydride thereof on a biodegradable polyester resin (A) comprising at least one structural unit selected from structural units represented by the following general formulae (1), (2), and (3): 

Biodegradable laminate

A resin composition is provided, which comprises: an ethylene-vinyl acetate copolymer (A); and a saponified ethylene-vinyl acetate copolymer (B) having an ethylene content of not less than 70 mol %, wherein the component (B) is present in a proportion of 1 to 30 parts by weight based on 100 parts by weight of the component (A). Where the resin composition is used in combination with a scrap laminate including a polyolefin resin layer and an EVOH layer for recycling the scrap laminate, die build-up is suppressed, and a product formed from the resulting recycled material is excellent in appearance and substantially free from coloration.
