JPS5829157Y2 - Film for both adhesion and adsorption - Google Patents

Description

[Detailed description of the invention] This invention utilizes the airtightness between applying an adhesive to one side of a soft transparent or opaque plastic film to serve as the adhesive surface for the adherend, and the other side being a smooth mirror surface. The present invention relates to a film that has a pressure-sensitive adsorption surface that adsorbs.

Traditionally, plastic adhesive tapes have the disadvantage that they are not only difficult to remove after use, but also that they tend to get dirty because the adhesive remains after adhesion and dirt and other substances adhere to them. In the case of tape, it adheres to the hand and is difficult to handle, and when the adherend is paper, it may tear when removed, or it may be easily removed if both sides of the tape remain attached to the target surface for a long period of time. This has disadvantages in that it becomes impossible to peel off and loses its adhesive effect each time it is reattached, making it unsuitable for use by reattaching it many times.

The purpose of the present invention is to eliminate such defects and to obtain a new adhesive/adsorption film that is extremely easy to reapply and does not stain the peeling surface. In the example shown, an adhesive is applied to one side of a soft plastic film, and a pressure-sensitive adhesive is applied to one side opposite to the adhesive surface 1 of the adherend, which adsorbs to a smooth mirror surface 6 using airtightness. It takes the form of the suction surface 2 and has the same adhesion and suction functions on both sides of the film.

If the film of the present invention is used in the form of a sheet, the adhesive surface 1 should be brought into close contact with the release paper 3, and the suction surface 2 should be brought into close contact with the mirror protective paper 4. For those to be used, roll the film directly into a spiral shape with the adhesive side 1 inside without using release paper or protective paper, and before use, cut the film to an appropriate size and attach the adhesive side 1 of the film. It is used by adhering the film to a body 5 and by adhering the adsorption surface 2 of the film to a smooth mirror surface 6.

In other words, if the adhesive surface 1 of the film is adhered to the adherend 5, the suction surface 2 on the opposite side will be exposed, making it possible to treat it as if it were the suction film itself, which is extremely convenient. It's convenient.

In addition, unlike the case of conventional adhesive tapes, the bond between the smooth mirror surface 6 and the adhesive is not adhesion or adhesion using an adhesive, but is merely suction, so by pulling the adherend 5, the suction surface 2 can be indirectly bonded. It is removable, easy to peel off, and easy to replace.

Moreover, it does not come off even after a long period of time has passed.

For example, the surface of an album mount can be coated with plastic to create a smooth mirror surface, and the film can be used to easily replace photos, or bulletin boards can be made of glass, decorative boards, etc.
If it is made of steel or a painted board with a mirror finish, it will have practical effects such as making it easier to adhere and remove posters more safely and cleanly than with thumbtacks or existing adhesive tapes. be.
