    摘要： A plastic film is provided in which brittleness has been improved, and which is not too soft, and which has practically satisfactory physical properties, heat-sealability stable with time, and biodegradability in natural environment. The film comprises a polylactic acid-family polymer and other aliphatic polyester at the ratio of 80:20 to 20:80, and the heat of fusion &Dgr;Hm1 converted to the polylactic acid-family polymer when the temperature of the film is raised is 35 J/g or under.

    摘要： In relation to a core sheet for card for forming an environment-reactive layered card having a plant raw material plastic as a main raw material, a core sheet for card for forming a novel layered card having excellent heat resistance, impact resistance, as well as adhesiveness between each layer (heat fuse-bonding ability), is provided. A core sheet for card is proposed, which is a core sheet for card (A) to be used together with an over-sheet (B) provided with a structure in which at least one layer is a layer having as a main component resin an aromatic polyester series resin or a polycarbonate series resin or a mixed resin of these both for the purpose of forming a layered card, including one layer or two or more layers that are layered, among which at least one layer is a lactic acid series resin layer having a lactic acid series polymer as a main component resin.
