Abstract
Disclosed is a surface protective film, a method for fabricating the same, and pouch, and a method for fabricating the same. The surface protective film includes a stack of films including a middle layer, and a first skin layer and a second skin layer on opposite sides of the middle layer, wherein at least one of the first skin layer and the second skin layer is formed of a resin having a hardness lower than a hardness of a surface to be protected by the surface protective film, and the middle layer is formed of a resin including high density polyethylene, thereby permitting protection of a display surface without formation of scratch at a very low cost compared to the related art without aging and with slip.
