Embodiment
[0064] The present invention will be further described below in conjunction with the accompanying drawings.
[0065] Such as Figure 1-2 As shown, a kind of easy-peelable PET protective film provided by the present embodiment comprises:
[0066] The waterproof layer 1, embossed layer 2, conductive layer 3, PET substrate layer 4, adhesive layer 5 and release film layer 6 are connected sequentially from top to bottom, and the embossed layer 2 is made of thermally expandable elastic material become.
[0067] Working principle of the present invention is:
[0068] The present invention provides an easy-to-peel PET protective film. The waterproof layer 1, the embossed layer 2, the conductive layer 3, the PET substrate layer 4, the adhesive layer 5 and the release film layer 6 are sequentially bonded, and the waterproof layer 1 is set The outermost layer prevents water and grease from remaining on the protective film and damages the protective film. The embossed layer 2 expands u...

Abstract
The invention discloses an easily stripped PET protective film and a preparation process thereof, the PET protective film comprises a waterproof layer, an embossing layer, a conductive layer, a PET base material layer, an adhesive layer and a release film layer which are sequentially connected from top to bottom, and the embossing layer is made of a thermally induced expansion elastic material. According to the PET protective film, when the temperature of the PET protective film rises, a material on the embossing layer expands, the deformation amount of the outer side of the embossing layer is larger than the deformation amount of the inner side of the embossing layer due to the fact that the protruding density of the outer side is larger than the protruding density of the inner side, the edge of the protective film is warped, the protective film is convenient to peel, and use convenience is improved.
Description
technical field [0001] The invention relates to the technical field of PET protective films, in particular to an easy-peelable PET protective film and a preparation process thereof. Background technique [0002] PET, namely polyethylene terephthalate, is a highly crystalline polymer with excellent wear resistance, electrical insulation, flame retardancy, heat aging resistance and low water absorption. Therefore, PET protective film with special protective properties is widely used in electronic products such as computers, digital cameras and mobile phones, and is attached to the surface to protect them from damage and pollution. Existing PET protective film is mainly made by adhering a layer of release film and a layer of PET protective film base material together, that is, after coating glue on the PET protective film base material, and then laminating a layer of release film. After use, the PET protective film will be peeled off manually or by a robot. The existing PET p...
