POLYPROPYLENE FILM AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: A polypropylene based film and a manufacturing method thereof are provided to have no product inferiority problem, process complication, and the cost rising problem of laminated product, since the film can be laminated directly on the adhered material simply without using adhesive of T-die process. CONSTITUTION: The polypropylene based film includes: a first skin layer; and a second skin layer. The central layer is composed of the polypropylene based resin. The first skin layer is composed of the polypropylene based resin formed in one side of the central layer. The second skin layer is directly closed to the adhered material in which film is laminated. The polyethylene resin of the second skin layer is the copolymer in which 1- butene or 1-octene is graft polymerized in the ethylene.
