Novel PE reticulated protective film

Abstract

The utility model relates to a novel PE (Poly Ethylene) reticulated protective film, which comprises a polyethylene film layer and an adhesive layer coated on one side of the polyethylene film layer, the adhesive layer is of a reticulated structure, the polyethylene film layer is provided with arrayed small holes, the aperture of the small holes is 0.1-0.3 mm, and the distance between adjacent small holes is smaller than the distance between corresponding sides of a single reticulated hole of the adhesive layer. As the arrayed small holes are formed in the polyethylene film layer, and the distance between the adjacent small holes is smaller than the distance between the corresponding edges of the single reticulate pattern hole of the adhesive layer, each mesh hole formed by the reticulate pattern is provided with the small holes, the protective film is attached to the surface of a part workpiece during production, and then the part workpiece is put into a negative pressure box, so that the surface of the part workpiece is protected; under the action of negative pressure, residual small bubbles attached to a protective surface can be pumped away, so that a film is tightly attached to the protective surface, the purpose of film pasting can be achieved without excessive mechanical actions in the film pasting process, protective film pasting of easily-damaged products is achieved, the film pasting quality is good, the workpiece effect is high, and parts are not prone to being damaged.

Description

Technical Field

[0001] This utility model relates to the field of protective film technology, and in particular to a novel PE textured protective film. Background Technology

[0002] Electronic products, optical products, and high-end handicrafts are easily scratched and contaminated during handling and production, necessitating the application of a PE protective film to these components. Currently, production primarily relies on mechanical lamination of protective films. However, mechanical lamination, with its numerous mechanical movements, particularly rolling, can easily damage products. This is especially problematic for some electronic products, instruments, and handicrafts, which are not suited to extensive mechanical lamination. Current mesh protective films are designed specifically for mechanical lamination, and no non-roll-pressed mesh protective film has yet been discovered. Therefore, it is essential to design a novel PE mesh protective film. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a novel PE textured protective film.

[0004] The technical solution adopted by this utility model is: a novel PE mesh protective film, comprising: a polyethylene film layer and an adhesive layer coated on one side of the polyethylene film layer, wherein the adhesive layer has a mesh structure, and the polyethylene film layer is provided with an array of small holes, the diameter of the small holes being 0.1 to 0.3 mm, and the spacing between adjacent small holes being less than the spacing between the corresponding sides of a single mesh hole in the adhesive layer.

[0005] This invention features an array of small holes on a polyethylene film layer, with the spacing between adjacent holes being smaller than the spacing between opposite sides of a single mesh hole. This ensures that each mesh hole in the mesh formation has small holes. During production, the protective film is attached to the surface of the component or workpiece, and then placed in a negative pressure chamber. Under negative pressure, residual small air bubbles attached to the protective surface are removed, and the film adheres tightly to the protective surface. This film application process does not require excessive mechanical action to achieve the desired effect, satisfying the protective film application needs of easily damaged products. The film application quality is high, the workpiece efficiency is high, and the components are less likely to be damaged. Attached Figure Description

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] like Figures 1 to 3 The diagram shown is a schematic diagram. To illustrate the structure more clearly, the holes and other structural elements are enlarged. This invention includes: a polyethylene film layer 1 and an adhesive layer 3 coated on one side of the polyethylene film layer. The adhesive layer has a mesh structure 2. The polyethylene film layer has an array of small holes 11, with a hole diameter of 0.1 to 0.3 mm. The spacing between adjacent holes is smaller than the spacing between corresponding edges of a single mesh hole in the adhesive layer. Figure 3 As shown, the spacing between the edges of a single mesh hole refers to the spacing between two mesh lines of the mesh structure 2, that is, the spacing between mesh line 21 and the adjacent mesh line 22. This ensures that small holes pass through each grid. Because the adhesive layer has a mesh structure with an array of small holes on the polyethylene film layer, the protective film is applied to the product or workpiece surface. For example, a flexible scraper can be used to scrape and press the protective film in one direction, first covering the product or component, and then placing it in a negative pressure chamber. Under negative pressure, residual air bubbles on the protective surface are removed, and the film adheres tightly to the protective surface. This type of film application does not require excessive mechanical action, especially strong mechanical action, to achieve the desired application. It meets the protective film application requirements for easily damaged products, is used to manufacture high-requirement products, is not easily damaged, has good application quality, and high work efficiency.
