According to the type, grade, quality of the labeling object, the characteristics of the pasting surface, the use environment and the user’s requirements, etc., comprehensive consideration. If you want to use a label made of polypropylene self-adhesive labels with good transparency to be attached to the transparent bottle body, it can produce a sense of fashion without labels, which can improve the grade of goods and stimulate consumers’ desire to buy. The flexibility, shrinkage, opacity, processing characteristics and labeling characteristics of PVC film are very good, and the color is bright, which has the effect of promoting and promoting products.
The thickness of the self-adhesive label must be uniform and the strength index must be qualified. The printing pressure applied during the printing process is related to the thickness of the sticker. If the thickness is not uniform, the printing pressure will also be uneven, which will cause the writing or ink color of the label to be dark or light. If the film strength is too poor, it will be difficult to control the tension of the film during the printing process, which will have a great impact on die cutting and waste discharge.
