Embodiment Construction
[0024] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0025] refer to figure 1 As shown, the present invention provides a protective film structure, which includes a three-layer structure: respectively: a transfer layer, a protective layer and a release layer; wherein, one side of the transfer layer and the protective layer has an adhesive surface; The specific distribution method is as follows: the adhesive side of the transfer layer is attached to the non-adhesive side of the protective layer; the adhesive side of the protective layer is attached to the release layer.
[0026] The structure of the protective film effectively solves the problem that the single-layer protective film is easily damaged by external forces, causing foreign matter to enter the prod...

The invention discloses a protective film structure and a protection method thereof, and belongs to the technical field of protective films. The protective film structure comprises a transferring-attaching layer, a protective layer and a release layer, and an adhesive surface is arranged on one side of each of the transferring-attaching layer and the protective layer; the adhesive surface side ofthe transferring-attaching layer is attached to the non-adhesive surface side of the protective layer; the adhesive surface side of the protective layer is attached to the release layer; and the uncovering force between the transferring-attaching layer and the protective layer is set to be Fa, the uncovering force between the protective layer and the release layer is set to be Fb, and the uncovering force between the protective layer and a attached object is set to be Fc, wherein Fa is greater than or equal to 3Fb, and Fc is greater than or equal to 3Fa. According to a protective film providedby the invention, by limiting the uncovering force between the different layers, the protective layer is taken down from the release layer at the same time when the transferring-attaching layer is uncovered; and the transferring-attaching layer is removed, the protection layer is reserved to protect the attached object, two-time protection modes can be formed, the surface of a base material can be protected against damage in the manufacturing process or the shipment process, and meanwhile the adhesive surface making contact with the attached object can further be prevented from being pollutedor damaged.
Description
technical field [0001] The invention belongs to the technical field of protective films, and in particular relates to a protective film with a multilayer film structure and a protection method thereof. Background technique [0002] With the rise of manufacturing industries such as electronic products, in order to prevent the surface of electronic products from being scratched or damaged, it is necessary to attach a protective film during the manufacturing and shipping of electronic products. The existing protective film is mostly a single-layer protective film attached to the product, which is easily damaged by external force, thus causing foreign matter to enter the product surface. [0003] In addition, when using a protective film in some special cases, the protective film attached to the product cannot be directly contacted or used directly, and another layer of protective film needs to be added on the protective film to transfer the protective film to be attached to the...
