The surface coating of pvc adhesive printing is actually a protective layer, the purpose is to make it better accept ink and easy to print, to prevent dirt, increase the ink adhesion and prevent printed pictures and pictures from falling off. Silicon silicon layer is to coat the silicon oil layer on the surface of the bottom paper, coating silicone oil can make the bottom paper become a surface tension is very low, very smooth surface, the role is to prevent the adhesive bonding on the bottom paper.
The pvc adhesive printing paper is to protect the adhesive on the back of the surface material, support the surface material, so that it can be die-cut, remove waste, and label on the labeling machine. As for the back printing, its role is to print the manufacturer's registered trademark or pattern on the back of the bottom paper, playing a role of publicity and anti-counterfeiting.
The surface is the material on the front and the adhesive on the back and eventually applied to the paste. The purpose of coating the bottom layer is to protect the surface material and prevent the adhesive penetration. Increase the impermeability of the fabric; increase the adhesive force between the adhesive material; prevent the plasticizer in the plastic surface material from infiltrating into the adhesive, affecting the performance of the adhesive and reducing the adhesion force of the label.
Finally, the pvc adhesive printing. Adhesive come in various formulations suitable for different surface materials and different occasions. It is the substance between the label material and the bonding substrate. It is also the most important component in pvc adhesive printing materials and is the key of label application technology.
