Pvc sticker printing material composition introduction

Pvc sticker printing is now widely used in trademarks, signage and other printing areas, from the surface point of view, pvc sticker printing material structure is composed of surface material, adhesive and bottom paper three parts. But professionals, pvc stickers printed to ensure quality, including back printing, coated with silicon and so on. 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 ink adhesion and prevent printing graphics from falling off. The silicon coating layer is coated with a silicone oil layer on the surface of the bottom paper. The coating of the silicone oil can make the bottom paper a surface with very low surface tension and a very smooth surface, and the function is to prevent the adhesive from sticking to the bottom paper.

The pvc sticker printed on the backing paper is to protect the adhesive on the back of the face material, supporting the surface material, enabling it to die-cut, discharge and labeling on the labeling machine. As for the back-printing, its role is to print the manufacturer's registered trademark or design on the back of the backing paper, which serves as a propaganda and anti-counterfeit.

The face material is a material that accepts the printed graphic on the front side, accepts the adhesive on the back side, and is finally applied to the attached article. The purpose of the primer is to protect the face material and prevent adhesive penetration. Increase the opacity of the fabric; increase the adhesive force between the adhesive and the surface material; prevent the plasticizer in the plastic surface material from penetrating into the adhesive, affecting the adhesive performance, resulting in the adhesive force of the label Lower, labels fall off.

The last is a pvc adhesive printed adhesive. Adhesives come in a variety of formulations for different face materials and different occasions. It is the substance between the label material and the bonding substrate that acts as a link. It is also the most important component in pvc adhesive printing materials, and it is the key to the label application technology.
