PURPOSE: A biodegradable lamination sheet is provided to resolve a problem regarding the supply of raw materials by using a plant source-based poly(lactic acid)(PLA) resins. CONSTITUTION: A biodegradable lamination sheet comprises a first base substrate layer(110), an adhesive layer(120), a second substrate layer(130), and a printed layer(140). The adhesive layer is formed on top of the first substrate layer. The second substrate layer is formed on top of the adhesive layer. The printed layer is formed on top of the second substrate layer. The adhesive layer includes a PLA resin. The biodegradable lamination sheet additionally includes a surface treating layer formed on top of the printed layer. The PLA resin is formed in sol form. The PLA resin is blended with a bioresin or a synthetic resin. [Reference numerals] (110) First substrate layer; (120) Adhesive layer; (130) Second substrate layer; (140) Printed layer
