Further, a protection film structure, from the type layer for from the type membrane or from type paper.

Further, the utility model discloses a protection film structure, its protection method is:

firstly, when the transfer layer is uncovered, the protective layer can be simultaneously brought down from the release layer and is jointly pasted on a pasted object for primary protection;

secondly, when the transfer layer is uncovered, the protective layer is retained on the pasted object for secondary protection.

Has the advantages that:

compared with the prior art, the utility model has the advantages that:

1. the protective film structure is protected twice in the using process through the multilayer film structure design, the requirement of multiple protection in the product manufacturing process is met, the product is effectively protected, and foreign matters are prevented from entering the surface of the product.

2. By setting the peeling force between the different film layers, namely: fa is more than or equal to 3Fb, Fc is more than or equal to 3Fa, so that when the transfer layer is uncovered, the protective layer is carried from the release layer; then the transfer layer and the protective layer are pasted on the surface of the pasted object together; and finally, removing the transfer layer and reserving the protective layer to protect the product.

Drawings

Fig. 1 is a schematic perspective view of a protective film structure provided by the present invention;

in the figure: 1-transfer layer, 2-protective layer and 3-release layer.

Detailed Description

The following describes the present invention in further detail with reference to examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1, the utility model provides a protective film structure, this protective film structure includes three layer construction: respectively as follows: a transfer layer, a protective layer and a release layer; wherein, one side of the transfer layer and the protective layer is provided with an adhesive surface; the specific distribution mode is as follows: the adhesive side of the transfer layer is adhered to the non-adhesive side of the protective layer; the adhesive side of the protective layer is attached to the release layer.

This protection film structure is effectual solved the individual layer protection film and received external force very easily and destroy and lead to the foreign matter to get into the product surface, perhaps under some special situation, when using the protection film, when pasting the protection film of paying on the product can not direct contact or can't directly use, need add the problem that the one deck protection film shifts the protection film of attached on the product in addition on this protection film, and concrete solution is:
