PET (polyethylene terephthalate) antistatic protective film

Abstract

The invention discloses a PET (polyethylene terephthalate) antistatic protective film. The protective film comprises a PET release film, an adhesive layer and a PET substrate, wherein an antistatic finish layer is arranged on one side of the PET substrate and is a PET polyester film; and the antistatic finish layer is fit with the PET release film via the adhesive layer. The protective film has the beneficial effects that the surface of the protective film is free from static material transfer; and the protective film has the functions of preventing dust and impurity adsorption and preventing static damages, improves the antistatic effect, enables the product performances to be durable and stable and can simultaneously achieve antistatic, adhesive-residue-free, repeated paste, ultrastrong antifouling and high transmittance effects.

Description

technical field

[0001] The invention relates to the field of protective films for electronic products, in particular to a PET antistatic protective film. Background technique

[0002] At present, the glass substrate surface of some electronic products is susceptible to contact pollution from some chemical substances or scratches from nails during handling and use. It is usually necessary to attach a protective film to the surface to protect it from damage and contamination.

[0003] The existing protective film is generally composed of a base material layer and an adhesive layer coated on the base material layer. The base material layer generally adopts ordinary polyester film, and polyester film is a kind of polymer film. Polymer has a small dielectric constant and is a non-conductor with high insulation performance and low resistance, so it is easy to generate static electricity. When this kind of protective film is used on electronic products, it is easy to absorb dust ...
