Abstract

The purpose of the invention is to provide a dust-proof film for a flat hole-containing part. The technical problem that the existing dust-proof film is easy to form dirt at a hole-receiving portion of a product is solved by adopting a two-layer film structure provided with adhesive-avoiding film holes. The structure of the dust-proof film comprises: a first transparent film layer, a second transparent film layer and adhesive film layers, wherein the second transparent film layer is provided with through holes adapted to positions of product hollowed-out portions, the upper and lower film surfaces of the second transparent film layer are uniformly equipped with the adhesive film layers, and the lower film surface of the first transparent film layer and the upper film surface of the secondtransparent film layer are glued through the adhesive film layer. The dust-proof film can form the clean film protection for the hole-containing part.

Description

technical field [0001] The invention relates to the technical field of dustproofing of planar parts with holes, in particular to a dustproof film for planar parts with holes. Background technique [0002] With the rise of the digital product industry such as mobile phones, attaching a protective film to the product casing has become an indispensable and necessary process before the product leaves the factory. The technical purpose of manufacturers attaching protective films to new products is usually to prevent dust and dirt from entering the pores and affecting the appearance of the product before leaving the factory. In the protective film that is often used in the prior art, the adhesive layer usually covers the entire film body evenly, so that when the film is attached to the surface of the product shell with pores, the exposed film in the pores is easy to adhere to dirt from the inside of the product, and the product inventory The longer the time, the more obvious the ...
