We buy goods in the supermarket, and the price tag on the goods is the self-adhesive label, which is a kind of representative of the self-adhesive label.

The self-adhesive label is composed of three parts: the flour, the adhesive layer and the backing paper. Generally, the flour and the adhesive layer are closely adhered and cannot be torn off. Before use, the three layers are connected together. When using, the backing paper is torn off, and then the left side is the flour. A lot of information can be printed on the surface material, such as bar code, unit price, logo, etc.

It is called self-adhesive label because the adhesive layer is oily, and the general shelf life is one year. During this year, the adhesive layer of the label will not dry. At the beginning of social development, we all printed the contents on paper, and then made paste glue when we used it, coated it, and then pasted it. Finally, we invented this product. The glue layer was not needed to be made when we used it, but was coated on the back in advance, and a layer of backing paper with an isolation layer was pasted to prevent it from being stained with dust and adhesion. When we used it, it was convenient and quick to tear off the backing paper and paste it. So when this kind of label was first produced, it was called self-adhesive label.
