Transparent PET Pressure Sensitive Adhesive Tape

PVC self-adhesive labels represent a new trend in the printing industry, with increasing applications. They can be used on household items such as hair serum labels and advertising labels, as well as industrial applications like battery labels, wire labels, tire labels, and warning labels. On the surface, the structure of PVC self-adhesive printing materials consists of the surface material, adhesive, and backing paper. However, as personnel introduce, to ensure quality, it also includes back printing and silicon coating.

The surface coating of PVC self-adhesive printing is actually a protective layer, designed to enhance ink reception and ease of printing, aiming to prevent soiling, increase ink adhesion, and prevent the detachment of printed images. The silicone coating involves applying a silicone oil layer on the base paper surface, which makes the base paper extremely smooth with low surface tension, thereby preventing adhesive from sticking to the base paper.

The backing paper for PVC self-adhesive printing is designed to protect the adhesive on the back of the face material, support the face material, and enable it to be die-cut, waste-separated, and labeled on labeling machines. As for the reverse printing, its purpose is to print the manufacturer's registered trademark or pattern on the back of the backing paper, serving as a form of promotion and anti-counterfeiting.

The face material is the surface that accepts the printed graphics and the back that accepts the adhesive, ultimately applied to the adhesive item. The purpose of the undercoat is to protect the face material and prevent the adhesive from渗透. It enhances the opacity of the fabric; increases the bond strength between the adhesive and the face material; and prevents plastic face material plasticizers from渗透 into the adhesive, affecting its adhesive properties and reducing the label's bond strength, causing label detachment.

Next is the adhesive for PVC self-adhesive label printing. The adhesive comes in various formulations, suitable for different substrates and applications. It acts as the bonding material between the self-adhesive label material and the base material, serving as a connector. It is also a key component in PVC self-adhesive printing materials and a crucial aspect of label application technology.
