Provided is a method for producing a polyethylene-based resin extruded foam sheet by extruding and foaming a foamable molten resin composition formed by kneading a mixture containing a low-density polyethylene, a physical blowing agent, and an antistatic agent, wherein the foam sheet has a thickness in a range of from 0.05 to 0.5 mm, and the antistatic agent is a polymeric antistatic agent having a melting point whose different from the melting point of the low-density polyethylene is in a range of from 10 to +10 C., and having a melt flow rate of 10 g/10 min or more. This method enables a novel polyethylene-based resin extruded foam sheet to be obtained that is of high quality such that formation of a small hole or a through-hole has been reduced or eliminated, and has both excellent strength and a shock-absorbing property despite a very small thickness even in medium- or long-term continuous production, and besides, exhibits a sufficient antistatic property, thus suitable as a glass plate interleaf sheet.

A method of fabricating a window deco film includes forming a hard coating layer, forming a deco layer on the hard coating layer, forming a light-shielding layer on the deco layer, and forming an acryl-based coating layer on the hard coating layer before forming the deco layer, or on the light-shielding layer. The window deco film may have a remarkably reduced thickness, and thus an entire thickness of an image display device including a window substrate to which the window deco film is applied may be also reduced. Additionally, even when the window deco film is attached to a curved window substrate, a bubble may not be generated at a curved portion of the window substrate. A mura caused by a retardation or a phase difference due to the window deco film may be suppressed. Thus, the window deco film may have an improved transmittance.
