Introduction of the material composition of PVC sticker printing

The surface coating of PVC sticker printing is actually a protective layer, the purpose is to make it better accept ink and easy to print, to achieve the purpose of preventing dirt, increasing the adhesion of ink and preventing the printing graphics from falling off. The silicon coating layer is coated with a layer of silicone oil on the surface of the base paper. The coating of silicon oil can make the base paper a very low surface tension, very smooth surface, the role is to prevent the adhesive from sticking to the base paper.

The bottom paper printed with PVC stickers is to protect the adhesive on the back of the face material and support the face material so that it can be die cut, discharged and labeled on the labeling machine. As for back printing, its role is to print the manufacturer's registered trademark or pattern on the back of the backing paper, which plays the role of publicity and anti-counterfeiting.

The face material is a material that accepts printed graphics on the front and accepts adhesive on the back and is finally applied to the adherend. The purpose of the primer layer is to protect the surface material and prevent the penetration of the 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, affecting its adhesive performance, resulting in the adhesion of the label Lower, the label comes off.

The last is the adhesive for PVC sticker printing. There are many kinds of adhesive formulas, suitable for different surface materials and different occasions. It is the substance between the label material and the bonding substrate, which plays a role of connection. It is also the most important component in PVC self-adhesive printing materials and the key to label application technology.
