The shrink sleeve labels has a long history, however, with the passage of time, shrink sleeve labels is more and more widely used, so what are the irreplaceable advantages of shrink sleeve labels? Why is it developing more and more rapidly?
Compared with the traditional label, the shrink sleeve labels has the advantages of no glue brushing, no paste, no water dipping, no pollution, saving labeling time, etc. It can be said that the printing of shrink sleeve labels is quite different from the printing of traditional printed matter. The shrink sleeve labels is usually printed and processed on the label linkage machine, which is completed by multiple processes at one time, such as graphic printing, die cutting, waste disposal, sheet cutting and rewinding. It can be seen that the shrink sleeve labels has higher requirements for printing technology and printing equipment.
Therefore, several points should be paid attention to when choosing shrink sleeve labels:
1. The label of shrink sleeve should be flat and the rewinding tension should be even. Only when the flatness is good can it be transported, operated, registered and rolled up correctly during printing. The rewinding tension of the film should be uniform and appropriate, such as the tension is too small, the film substrate is loose, and the vertical and horizontal overprinting is not allowed; If the tension is too high, the substrate shrinks transversely, and the color registration is unstable, which makes it difficult to print normally.
2. The thickness of shrink sleeve labels should be uniform, and the strength index should be qualified. The printing pressure applied in the printing process is related to the thickness. If the thickness is uneven, the printing pressure will be uneven, which will lead to the deep and shallow handwriting or ink color of the label printed matter. If the film strength is too poor, it will be difficult to control the film tension in the printing process, which will have a great impact on die cutting and waste disposal.
3. According to the type, grade, quality of shrink sleeve labels, characteristics of sticking surface, use environment and user requirements, etc. If the label made of polypropylene label with good transparency is attached to the transparent bottle body, it can create a fashion feeling without label, which can improve the grade of goods and stimulate consumers' desire to buy. However, PVC film has excellent flexibility, shrinkage, opacity, processing characteristics and labeling characteristics, and has bright colors and great contrast, which can attract people's attention and play a role in promoting and promoting goods.
