PROBLEM TO BE SOLVED: To provide biodegradable laminated paper, in which a processing stability in lamination is remarkably improved, and heat-sealing properties are also excellent, and which, if necessary, can be made easily peelable.SOLUTION: In the biodegradable laminated paper, a layer of a polylactic acid independently or a composition (B) of the polylactic acid with other biodegradable aliphatic polyesters is laminated on at least one side of a paper substrate via a layer of a lactic acid based aliphatic polyester (A) including 0.7-10 wt.% of a lactic acid. |
