Problems solved by technology

[0002] The existing surface protection materials for die-cut products directly cover the surface of the product with PET film. In the actual process, after the PET film is compounded on the surface of the product, because the core area of ​​the product has a certain The overall flatness of the PET film is not good, which easily makes the overall flatness poor, which in turn reduces the overall protection effect of the PET film on the product and the overall appearance of the product.

Embodiment Construction

[0017] A cohesive and release double-layer composite material, see figure 1 , figure 2 : It includes a PET protective film 1, a release film 2, the PET protective film 1 includes a first PET base layer 11, an antistatic coating 12, a silica gel layer 13, and the release film 2 includes a second PET base layer 21, a silicone oil coating 22. The exposed surface of the silica gel layer 13 is compounded with the non-silicone oil coating surface of the second PET matrix layer 21 .

[0018] See figure 2 : the exposed surface of the silicone oil coating 22 is used to cover the peripheral area of ​​the product, the second PET base layer 21 is corresponding to the thickness of the product, and the convex part is removed by punching and waste, forming a gap 23, and the thickness of the product is convex. Only the PET protective film 1 is kept, and the silicone layer 13 of the corresponding area of ​​the PET protective film 1 is directly attached to the surface of the convex part of ...

Abstract

The invention provides a double-layer composite material with stickiness and release, which makes the core area of ​​the product with thickness flatly attached to the PET film, and ensures that the periphery of the product is protected, ensuring that the surface of the product is protected. Flatness stickers. It includes a PET protective film and a release film, the PET protective film includes a first PET base layer, an antistatic coating, a silica gel layer, the release film includes a second PET base layer, a silicone oil coating, and the silica gel layer The exposed surface of the second PET base layer is composited with the non-silicone oil coating surface.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a double-layer composite material with adhesion and release. Background technique [0002] The existing surface protection materials for die-cut products directly cover the surface of the product with PET film. In the actual process, after the PET film is compounded on the surface of the product, because the core area of ​​the product has a certain The overall flatness of the PET film is not good, which will easily make the overall flatness poor, and then reduce the overall protection effect of the PET film on the product, and the overall appearance of the product is not good. Contents of the invention [0003] In view of the above problems, the present invention provides a sticky and release double-layer composite material, which makes the core area of ​​the product with thickness flatly attached to the PET film, and ensures that the periphery of the product is pro...
