Technical Field

The invention belongs to the field of preparation of release paper, and particularly relates to release paper for producing a close-contact adhesive tape.

Background

Release paper is also called as release paper and release paper, and along with the development of the society, the release paper needs to be used in a large amount in the industrial production process, so that the application of the release paper is more and more extensive. The release paper can be used in the fields of production of protective films of metal products, adhesive tapes, printing, food, medical use, decoration, mobile phone films and the like, and has wide market prospect.

However, when the existing release paper is used for an adhesive tape or a release film, the main problems are as follows: at present, the conventional release paper is compounded with an adhesive tape or an adhesive film to form the adhesive tape or the release film, and when the adhesive tape or the release film is used, the release paper is peeled off, and the adhesive tape or the release film is adhered to the surface of an object. Because the adhesive tape or the release film is soft, the generated bubbles are not easy to discharge, and the problem of unevenness is formed, thereby influencing the using effect of the adhesive tape or the release film.

Based on the situation, the invention provides release paper for producing a close-contact adhesive tape, which can effectively solve the problems.
