    摘要： Provided is a molded body where aliphatic polycarbonate and polypropylene are laminated in two or more layers, and more particularly, if aliphatic polycarbonate and polypropylene according to the present invention are co-extruded and bi-axially oriented, since two layers are easily attached by only a simple process while an additional process for introducing a barrier layer and an adhesion agent or a adhesion layer (tie layer) are not provided, stripping does not occur, excellent oxygen barrier property may be provided as compared to only bi-axially oriented polypropylene, in the case where aliphatic polycarbonate is present on a surface layer, a heat sealing property and a thermal adhesion property to paper may be provided at low temperatures, and an additional adhesion agent or adhesion layer (tie layer) are not required, cost is reduced and a layer constitution is simplified to significantly reduce manufacturing costs.

    摘要翻译： 提供了一种成型体，其中脂肪族聚碳酸酯和聚丙烯层压成两层或更多层，更具体地，如果根据本发明的脂族聚碳酸酯和聚丙烯是共挤出和双轴取向的，则由于两层仅容易地附着 不提供用于引入阻挡层和粘合剂或粘合层（粘结层）的附加方法的简单方法，不会发生剥离，与仅仅双轴取向的聚丙烯相比，可以提供优异的阻氧性， 在表面层上存在脂肪族聚碳酸酯的情况下，可以在低温下提供对纸的热封性和热粘合性，并且不需要额外的粘合剂或粘合层（粘结层），成本降低 并且简化了层结构以显着降低制造成本。

    摘要： Provided is a composition for paper coating, including aliphatic polycarbonate having an average molecular weight of 50000˜3000000 obtained by reaction of one or at least two different kinds of epoxide compounds selected from the group consisting of (C2-C10)alkylene oxide substituted or unsubstituted with carbon dioxide, halogen, or alkoxy; (C4-C20)cycloalkylene oxide substituted or unsubstituted with halogen or alkoxy; and (C8-C20)styrene oxide substituted or unsubstituted with halogen, alkoxy, alkyl or aryl. Also, provided is a method for coating a paper, by extrusion-coating the composition for paper coating at 150 to 230° C. on the paper to manufacture a coated paper.
