A polyglycolic acid resin-based multilayer sheet is formed by laminating a biological polymer substrate sheet and a polyglycolic acid resin with each other via an aqueous adhesive layer. The multilayer sheet is formed of biodegradable materials as a whole and allows recovery of paper, etc. alone, as desired, by preferential decomposition of the resin, thus being suitable as a packaging material stock for food container, etc.
