PURPOSE: A self-adhesive protection film for fabrication process is provided to prevent the surface scratch during the manufacturing of a polarizer, thereby having excellent slipability of an outer layer. CONSTITUTION: A self-adhesive protection film for fabrication process comprises a first layer, a second layer, and a third layer. The first layer(8) comprises polypropylene, which is the homopolymer of polypropylene, or copolymer of polypropylene. The thickness ratio of the first film is 20-40 %. The first layer additionally comprises a blocking prevention agent. The second layer(10) comprises polyethylene[LDPE]. The thickness ratio of the second layer is 30-50 %. The third layer(11) comprises ultra low density polyethylene [LLDPE], and metallocene polyethylene. The weight ratio of the ultra low density polyethylene [LLDPE] and the metallocene polyethylene is 70-30:30-70 wt% range. The thickness ratio of the third film is 20-40 %.
