Special gluing protection film for advertising as well as preparation method and glue coating equipment of gluing protection film

Abstract

The invention provides a special gluing protection film for advertising as well as a preparation method and glue coating equipment of the special gluing protection film and relates to a sticking film for the advertising, a preparation method of the sticking film and a glue coating device of the sticking film. The special gluing protection film for the advertising is prepared from a surface film layer (1) and a glue layer (2) through gluing, wherein the surface film layer (1) comprises at least one layer of a polypropylene raw material, the glue layer (2) is located on the bottom surface of the surface film layer (1), and the surface film layer (1) is jointly glued with an advertising picture through the glue layer (2) during use. The structure is simple, the raw material cost and the processing cost of body paper can be reduced during production, and the cost can be reduced by 50% or higher; during application, the gluing protection film is convenient to stick and can be used rapidly, the work cost for removing the body paper is omitted, production of waste is reduced, the environment pollution is avoided, so that the production efficiency is greatly improved, the application cost is reduced, and the product competitiveness is improved.

Description

technical field [0001] The invention relates to an advertising film, in particular to an advertising film, a method for making the film and a glue coating device for the film. Background technique [0002] The traditional advertising film is composed of a PVC film and a silicone oil-coated release backing paper mask. When used, it needs to use a solvent to remove the backing paper before it can be attached. As a result, it not only causes a lot of waste materials, wastes resources, pollutes the environment, and is not environmentally friendly. , while increasing the cost of use, when in use, the speed of mounting the picture is slow, the effect is poor, and problems are prone to occur. And the use of solvents to remove the oil glue pasted on the backing paper will cause corrosion, which will affect the picture clarity of the film, resulting in poor use effect. Thereby, the advertising film without base paper will become the development trend, but, because the restriction of...

AI Technical Summary

Problems solved by technology

Although the PVC material is soft, it has shrinkage, which is difficult to be suitable for film application. The mask made of OPP raw material is easy to harden, resulting in wrinkling, arching, blistering, and unevenness of the paper after mounting, which is serious. Affect the effect of use, or even unusable

And because it will be hard, the flexibility is poor, and it cannot be spliced. Its defects are more obvious when it is applied to non-planes (such as corners), so it is difficult to popularize

Moreover, when the traditional OPP advertising film is stretched and attached, not only can it not be rolled back and bent (rewinding or bending will cause the advertising film to be degummed or damaged and cannot be used), it will also cause huge noise

[0003] Moreover, since the advertising film made of OPP raw materials cannot be rolled small, reversed and bent, it not only increases the difficulty of transportation during transportation, but also tends to be scrapped
