Remove matte release film, according to shape of product removal corresponding region matte release film after layer of silica gel remaining adhesion rate >=
85%;
The antistatic parameter of the glue surface of the antistatic coating is 106-1011 Ω, and pre- antistatic is excessive to adsorb product.
After adopting the above technical scheme, being combined with each other without silicone oil face by the layer of silica gel of PET protection film and release film, multiple
Closing the Matte film on protective film has good flexibility and docile property, compound easily to cause fold bubble etc. up
Bad, release film effectively realizes the structure that entire material forms indent Jiao Qu by punching press waste discharge, release film composition
Material is conveniently taken in adhesive-free area, the glue surface with faint viscosity of PET protection film protects the surface for protecting product, which reduce
The cost of raw material;And release film punching can cut out required shape, also there is good planarization as auxiliary film;To sum up,
PET film in its fitting for making the nucleus with thickness of product smooth, and the periphery for ensuring product guarantees with protection
The planarization on the surface of product is attached.

Fig. 1 is schematic diagram of product structure of the invention;
Fig. 2 is to be formed after being punched waste discharge on release film for attaching the structural schematic diagram of product;
Title corresponding to serial number is as follows in figure:
PET protection film 1, the first PET matrix layer 11, antistatic coating 12, layer of silica gel 13, release film 2, the second PET matrix
Layer 21, silicone coating 22, notch 23.
Specific embodiment
A kind of toughness and release double-layer composite material, see Fig. 1, Fig. 2: it includes PET protection film 1, release film 2, PET
Protective film 1 include the first PET matrix layer 11, antistatic coating 12, layer of silica gel 13, release film 2 include the second PET matrix layer 21,
Silicone coating 22, the exposed surface of layer of silica gel 13 are compounded with the non-silicone coating face of the second PET matrix layer 21.
See Fig. 2: the exposed surface of silicone coating 22 is used for the peripheral surface domain region of laminating product, the second PET matrix layer 21
By punching waste discharge removal, formation notch 23, the thickness concave portion of product only retains thickness concave portion corresponding to product
There is PET protection film 1, the layer of silica gel 13 of the corresponding region of PET protection film 1 directly attaches the table of the thickness concave portion of product
Face, it is ensured that the overall leveling of PET protection film 1;
PET protection film 1 is specially blue PET protection film, and release film 2 is specially matte release film, so that integral product is filled
When release film and protective film dual role, blue PET protection film was both protected to correspond to the Jiao Qu's of area's product thickness concave portion
The surface in viscosity and the area Fei Jiao, and have the fool proof above color;
Thickness of the thickness of matte release film no more than the thickness concave portion of product, it is ensured that the glue of blue PET protection film
Area attaches the thickness concave portion of product;
