Problems solved by technology

[0005] First, during transportation, scratches are generated on the surface due to the lack of smoothness between the protective film and the object to be protected, that is, the adhesive material, that is, the so-called pol-dirty phenomenon occurs, resulting in product failure
[0006] In addition, wrinkling occurs when additives such as slip agents are inserted, and migration of the antistatic agent occurs when the humidity rises when the antistatic agent is added, resulting in poor sliding and scratches

Abstract

Provided are a protective film and a manufacturing method thereof, in which the protective film includes a co-extruded film composed of an intermediate layer, and a first skin layer and a second skin layer present at both sides with the intermediate layer being disposed therebetween, wherein one or more layers of the first skin layer or the second skin layer contain polymer-based antistatic agents consisting of ethylene-based unsaturated carboxylic acids.

Description

technical field [0001] The present invention relates to a protective film and a manufacturing method thereof. Background technique [0002] In various display devices such as liquid crystal display (LCD), cathode ray tube (CRT), plasma display (PDP), etc., or products such as architectural glass materials, it is easy to occur due to product assembly, manufacturing, transportation, Dust and foreign matter caused by static electricity generated during storage, etc., or damage caused by scratches, so a protective film is used to prevent such damage. [0003] As the above-mentioned protective film, there are, for example, a protective film in which an adhesive is applied to a polymer film, a protective film in which a hard coat layer is applied to a polyethylene terephthalate (PET) film, and In these films, additives such as slip agents and antistatic agents are used as protective films. [0004] However, according to the research results of the inventors of the present invent...
