摘要： PURPOSE: a polyolefin-based coextrusion oriented polypropylene film and a master batch for preparation of an adhesive layer are provided, to allow a film to be extrusion coated without the treatment of a primer. CONSTITUTION: The polyolefin-based coextrusion oriented polypropylene film comprises a center layer (II) comprising a polypropylene resin, and a surface layer (I) and an adhesive layer (III) which are formed by coextrusion. The adhesive layer (III) comprises 100 parts by weight of a mixture comprising 10-100 wt% of at least one selected from the group consisting of a low density or middle density high pressure polyethylene having a melting point of 50-130 deg.C and a density of 0.990-0.935 g/cm¬3, a linear low density polyethylene having a density of 0.880-0.940 g/cm¬3, ethylene-vinyl acetate copolymer ethylene-acrylic acid copolymer, ethylene-alkyl acrylate copolymer, ethylene-methacrylic acid copolymer, linear polyethylene obtained by copolymerization using a metallocene catalyst, and 0-90 wt% of a polypropylene resin; and 0.05-2.0 parts by weight of a processing auxiliary.
