Multi label, as the name implies, is a label that covers many layers of different content on a label, and is used for some special requirements to achieve a label for a multi - functional object. Label also known as self adhesive stickers, but also can be called as multilayer stickers. The production of multi label use special equipment industrial production, equipment automation molding, the equipment and process requirements are relatively high. Multilayer labels from the two layer tag (double label), the three layer of labels, four layers of labels, five layers of labels, the use of more than five layers of less, but also the realization of automated production process is very difficult.
Multilayer labels can be divided into the following types:
1, double bottom paper label. Special material, surface material under the double bottom paper, in which the first layer of the back of the paper with adhesive with second layers of bottom paper glued to one. When the surface material is printed, the die cutting is used together with the first layer of paper to cut through and waste. When the label is applied, the surface material is peeled off and pasted on the commodity with the first layer of the bottom paper. When required, the label will be removed (leaving the first layer of paper) to the relevant article.
2, double label paper. Materials for the two coating process. The technological process is as follows.
A. common adhesive materials on the printed text.
B. coating on the surface of paper with silicone oil, silicone oil as graphic base paper.
The C. uses the bottom paper again coated adhesive, a double paper label material.
Again, D. printing die-cutting together with second layers of paper cut together side by side become waste, double label paper.
Using the method of double label paper and the double bottom paper is basically the same. The double layer label can be respectively processed on the printing machine and the coating machine, and can also be processed on the special equipment.
3, three or more layers of label printing processing in high-grade multifunctional rotary labeling machine, the basic principle is as follows.
A. two rolls of paper or more paper in two groups of printing devices on the same time printing.
B. two volume (or multi roll) materials, one for self adhesive, the other is usually thin paper materials. After printing the thin material by folding, finally with local gluing adhesive materials are stuck into a whole.
Overall, the C. composite material after cutting waste and rewinding or cutting a multilayer paper label.
Is increasingly used in cosmetics label, food label, drug class label, electronic product labels and home commodity label, in the connotation of small size cover a huge amount of information, is a promotion of the ideal tool.
Use can be widely used:
1, day of product category
2, publicity and promotion category
3, household goods category
4, medicine and health care category
5, the daily information class
