PVC self-adhesive and coated paper self-adhesive

 The structure of PVC self-adhesive printing material consists of three parts: surface material, adhesive and backing paper. But professionals said that in order to ensure quality, PVC self-adhesive printing also includes back printing, silicon coating and so on.

The surface coating of PVC self-adhesive printing is actually a protective layer, which aims to better accept the ink and be easy to print, so as to prevent dirt, increase the adhesion of ink and prevent the falling off of printed graphics. Silicon coating is to apply silicon oil layer on the surface of the backing paper, which can make the surface tension of the backing paper very low and the surface very smooth. Its function is to prevent the adhesive from sticking to the backing paper.

The backing paper of PVC self-adhesive printing is to protect the adhesive on the back of the surface material and support the surface material so that it can be die-cut, discarded and labeled on the labeling machine. As for back printing, its function is to print the manufacturer's registered trademark or pattern on the back of the backing paper to promote anti-counterfeiting.

The surface material is the material printed on the front, the back receives the adhesive and is finally applied to the adhesive. The purpose of the coating primer is to protect the surface material and prevent the penetration of adhesive. Increase the opacity of the fabric, increase the adhesion between the adhesive and the surface material, prevent the plasticizer in the plastic surface material from penetrating into the adhesive, affect the performance of the adhesive, reduce the adhesion of the label and fall off the label.

Finally, the adhesive for PVC self-adhesive printing. Adhesive formulations are diverse and suitable for different surface materials and occasions. It is the material between the label material and the bonding substrate, which plays a connecting role. It is also the most important component of PVC self-adhesive printing materials and the key of label application technology.

 Coated paper, also known as coated paper. Coated paper is coated with a layer of white paint on the surface of base paper and processed by super calendering. It is divided into one side and two sides, and the paper surface is divided into smooth surface and cloth pattern. The paper has smooth surface, high whiteness and good ink absorption and inking performance. It is mainly used for offset printing, gravure printing and fine screen printing, such as advanced picture books, calendars, books and periodicals.
