Abstract

A method and a product of one-time enveloping silicone gel with plastic films. The surfaces of two films to be in contact with the silicone gel are treated by a plasma casing process (crosslinking by activated species of inert gases) or an electron beam process in advance so as to improve the wetting capability thereof. Thereby the films and the silicone gel are able to tightly combine together without the fear of separation. The operation is carried out under a vacuum environment so that no bubble will be generated therein and the leakage of the silicone gel on welding portions will be prevented.

Claims

1. A method for enveloping silicone gel with plastic films, comprising the steps of:

providing a first plastic film with a first surface and a second plastic film with a second surface to contact with the silicone gel;

performing a surface implement process to the first and the second surfaces to improve a surface wetting capability of the first and the second plastic films; and

applying the silicone gel in the first and the second plastic films to be contact on the first and the second surface to envelope the silicone gel therein.

2. The method of claim 1, wherein the surface implement process is a plasma-casing process.

3. The method of claim 1, wherein the surface implement process is an electron beam process.

9. The method of claim 1, wherein the surface implement process is a plasma-casing process.

10. The method of claim 1, wherein the surface implement process is an electron beam process.

11. A product of the silicone gel enveloped in the first and the second plastic films made according to the method claimed in claim 1.

4. A method for enveloping silicone gel with plastic films, comprising tightly enveloping silicon gel in a first and a second plastic films under a vacuum environment without generating any bubble and air and leak between two enveloped plastic films.

5. The method of claim 4, wherein the first plastic film has a first surface and a second plastic film has a second surface to contact with the silicone gel, and a surface implement process is performed to the first and the second surfaces to improve a surface wetting capability of the first and the second plastic films.

6. The method of claim 4, wherein the surface implement process is a plasma-casing process.

7. The method of claim 4, wherein the surface implement process is an electron beam process.

12. A product of the silicone gel enveloped in the first and the second plastic films made according to the method claimed in claim 4.

8. A method for enveloping silicone gel with plastic films, comprising the steps of:

providing a first plastic film with a first surface and a second plastic film with a second surface to contact with the silicone gel;

performing a surface implement process to the first and the second surfaces to improve a surface wetting capability of the first and the second plastic films; and

tightly enveloping the silicon gel in the first and the second plastic films under a vacuum environment without generating any bubble and air and leak between two enveloped plastic films.

13. A product of the silicone gel enveloped in the first and the second plastic films made according to the method claimed in claim 8.
