What are the multi-layer labels used on labeling machines?

Labeling is an essential factor in the production of labeling machines, and the labels used on labeling machines are now becoming more and more diverse. Today we will talk about what is multi-layer labeling? And what are the advantages of such labels? Labeling machine multi-layer label is a multi-layer self-adhesive label raw materials in special equipment using special technology printing and processing into a layered label, this label is mostly used in self-adhesive labeling machine, and multi-layer label can be divided into the following types.

　　① self-adhesive labeling machine double-layer backing paper labels. Special materials, double-layer backing paper under the surface material, the first layer of the backing paper with the second layer of adhesive backing paper sticky as one. Face material after printing die-cutting, together with the first layer of backing paper cut through and together with the waste. When the label is applied, the face material is removed together with the first layer of backing paper and attached to the product. When needed, the label is removed again (leaving the first layer of backing paper) and applied to the relevant item.

　　② self-adhesive labeling machine double-sided paper labels for the second coating processing materials, the process flow is as follows.

　　a. Ordinary self-adhesive material is printed with graphics. 

　　b. Silicon oil is coated on the face paper to become a silicon oil backing paper with graphics.

　　c. This backing paper is coated again with self-adhesive, becoming a double-sided paper label material.

　　d. When printing and die-cutting again, cut through and scrap together with the second surface paper to become a double-faced paper label. The use of double-sided paper labels and double backing paper is basically the same. Double-sided labels can be processed separately in the printing machine and coating machine. Can also be processed in a special equipment.

　　③ multi-layer labels, printing and processing on high-grade multi-functional rotary labeling machine, the basic principle is as follows.

　　a. Two rolls of paper are printed simultaneously on two sets of printing devices.

　　b. Two rolls of material, one for the self-adhesive, the other is usually a thin paper-like material. Multi-layer label printing after the thin material by folding, local glue coating and finally with the self-adhesive material sticky as one.

　　c. Composite materials after the overall die-cutting, waste, rewinding or cut sheet into multi-layer paper labels. This type of label is like a small manual or instruction booklet that has not been opened, tear open the thin face paper and self-adhesive face paper bonded part, open the folded label, you can read the information on the front and back. Achieve the purpose of a label as an instruction manual.

　　Multi-layer labels with its complex processing technology, special requirements for equipment, generally suitable for mass production. Due to the special characteristics of multi-layer labels, and has a certain anti-counterfeiting effect, suitable for use in high-grade, high value-added goods. These labels have been widely used in the market for labeling on various products, forming a new trend of labeling.
