Self-adhesive label material is also called self-adhesive label material. It is a composite material with paper, film or special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the base paper.

Adhesive backing is one of the important features of stamps. The world's first stamp, the Penny Black, had adhesive backing when it was born.

The difference is that the two materials are different. The self-adhesive is suitable for surface gloss, while the back adhesive is only used for pasting stamps. To give a vivid metaphor, self-adhesive is actually transparent glue, but it has graphics and text printed on the surface; while the back glue is actually double-sided tape, used to bond two unglued products together.

Characteristics of self-adhesive tapes

Low investment and quick results. Self-adhesive printed matter is mostly trademarks and stickers, with smaller format, fast printing speed and less production waste.

Flexible printing methods. Self-adhesive stickers are not restricted by printing methods. Traditional printing factories can use offset printing machines or screen printing machines for printing.

With many functions, self-adhesive stickers are widely used in food, cosmetics and barcodes. They can also be used as signs for electronic products, mechanical products and other special environments.

Classification of self-adhesive labels

Self-adhesive labels are roughly divided into two types: one is paper self-adhesive labels, and the other is film self-adhesive labels.

1. Paper self-adhesive labels are mainly used for liquid washing products and popular personal care products; film materials are mainly used for mid-to-high-end daily chemical products. At present, popular personal care products and household liquid washing products account for a large proportion on the market, so the corresponding paper materials are used more.

2. PE, PP, PVC and other synthetic materials are commonly used for film self-adhesive labels. The film materials mainly include white, matte and transparent.

Since the printability of film materials is not very good, corona treatment is generally performed or a coating is added to the surface to enhance its printability. In order to prevent some film materials from deforming or tearing during the printing and labeling process, some materials will also undergo directional treatment and undergo uniaxial stretching or biaxial stretching. For example, biaxially stretched BOPP materials are quite commonly used.
