Foaming adhesive film capable of being printed in inkjet manner, and preparation method thereof

Abstract

The invention discloses a foaming adhesive film capable of being printed in an inkjet mode, and a preparation method thereof. The foaming adhesive film comprises a base material, a coating arranged onone side of the base material in a coating mode and an adhesion layer arranged on the other side of the base material in a coating mode, wherein a release layer is attached to the adhesion layer, a foaming air guide layer is further arranged between the base material and the adhesion layer, a layer of micro bubbles which are communicated with each other are arranged in the foaming air guide layer, part of the micro bubbles are communicated with the adhesion layer, and part of the micro bubbles on at least one side of the foaming air guide layer are communicated with the outside. According tothe invention, by arranging the foaming air guide layer, micro bubbles in the foaming air guide layer can be compressed by pressing the foaming air guide layer in the film gluing process, and then airin the bubbles formed on the gluing face is sucked into the micro bubbles, so that the effect of eliminating the bubbles on the gluing face is achieved, and the gluing face is kept clean and tidy; and due to the fact that many micro-bubble structures are arranged in the foaming air guide layer, so that the adhesive film is endowed with large internal stress, and the adhesive film can be completely torn off when torn off, and residues are reduced.

Description

technical field [0001] The invention relates to the technical field of advertising materials, in particular to an inkjet-printable foam adhesive film and a preparation method thereof. Background technique [0002] Inkjet printable film is a widely used advertising material. Its structure mainly includes a base material. A coating can be added on the surface of the base material to meet the requirements of inkjet printing and printing. There is an adhesive layer and a release type on the back of the base material. The adhesive layer is generally pressure-sensitive adhesive, and the release layer is generally paper or plastic film coated with a release agent. [0003] The above-mentioned film needs professional technicians to stick the film on the surface that needs to be pasted. The glue surface of the ordinary film is generally a smooth surface. , the film will quickly stick to the surface of the object to be pasted, resulting in the air between the film and the surface of ...

Problems solved by technology

[0005] However, in the above scheme, there are a large number of air guide lines on the release surface. Although it can have a certain exhaust effect, it is easy to enter a large amount of dust in the air guide lines when the product is placed for a long time. The main effect is to cover the adhesive layer and maintain the effective adhesive force of the adhesive layer. When using the film, tear off the release surface and let the adhesive layer directly adhere to the target object to achieve a fixed effect. If a large amount of dust enters the pattern, the adhesive force of the adhesive layer will be significantly reduced, which is not conducive to the normal use of the film
