technical field

The invention relates to the technical field of adhesive structures, in particular to the technical field of designing double-sided adhesive stickers.

Background technique

3M Plate Adhesive Tape is a double-sided tape that plays two main roles in flexo printing: 1. Fix the printing plate on the printing plate roller or its sleeve to prevent the printing plate from lifting or shifting during the printing process and ensure The printing process is carried out normally; 2. By selecting the density of the tape foam core material, the printing pressure can be finely controlled to match the graphic design of the printing plate and improve the printing effect.

For the production process of foam adhesive stickers, it is necessary to use mutually adaptive process methods to produce suitable and high-quality adhesive stickers.

At present, the existing double-sided adhesive tape is easy to stick to the fingers during use, so that the sticky surface of the double-sided adhesive tape is easy to be contaminated with foreign matter, which affects the firmness of the adhesion, and it is not easy to tear off during use. It is easy to deform the double-sided adhesive tape during the digging process, so that it cannot be well bonded to the component. Therefore, it is necessary to improve the double-sided adhesive tape.
