What is a sticker?

Self-adhesive, also known as self-adhesive label material, is a composite material with paper, film or special material as fabric, adhesive coated on the back and silicon-coated protective paper as backing paper. There are many coating technologies, which lead to the formation of different grades of self-adhesive materials. The development direction is from traditional roll coating, blade coating to high-pressure tape casting coating to ensure the uniformity and sensitivity of coating to the greatest extent, avoid bubbles and pinholes and ensure the coating quality.

Compared with ordinary printing, self-adhesive has the following characteristics:

1, with small investment and quick effect. Self-adhesive printed matter is mostly trademarks and self-adhesive, with small format, fast printing speed and less production waste.

2. The printing method is flexible. Self-adhesive is not limited by printing methods, and traditional printing plants can use offset printing machines or screen printing machines for printing.

3, multifunctional, self-adhesive is widely used in food, cosmetics and bar codes, and can also be used for signs of special environments such as electronic products and mechanical products.

There are two kinds of self-adhesive labels: 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 high-end daily chemical products.

2. Synthetic materials such as 2.PE, PP and PVC are often used for film self-adhesive labels. The film material is mainly white, matt and transparent. Because the printability of film materials is not very good, corona treatment or coating on its surface is usually used to enhance its printability.
