|Title:||MULTILAYER FILM COMPRISING POLYALKYLENE CARBONATE AND METHOD FOR MANUFACTURING SAME|
The present invention relates to a multilayer film comprising polyalkylene carbonate. Particularly, since the multilayer film comprises a core layer, which is obtained by blending polyalkylene carbonate and an ethylene vinyl acetate copolymer in a predetermined range, and an outer layer of polyolefin, two layers are bonded to each other, without an adhesive or a tie layer, only by a simple process without an additional process for introducing an oxygen barrier layer such that peeling does not occur and excellent oxygen barrier properties can be imparted. Furthermore, since a separate adhesive and a tie layer are not required during the manufacturing process, without an additional process for imparting barrier properties, the cost can be reduced. In addition, since the configuration of the layers can be simplified, the manufacturing cost can be greatly reduced.
