Problems needing attention in the production and use of self-adhesive labels

First of all, we need to comprehensively consider the characteristics, grade, quality, characteristics of the pasting surface, use environment and user requirements of the labeling object. For example, pasting a polypropylene self-adhesive label with good transparency on a transparent bottle can produce a label-free fashion feeling, improve the grade of the product, and stimulate consumers' desire to buy.

Secondly, for film-type self-adhesive labels, the surface needs to be smooth and compact, with uniform density, consistent color, and good light transmission, so as to ensure that the ink is evenly absorbed during the printing process of the label, and to ensure the color consistency of the same batch of products .

In addition, the thickness of self-adhesive labels must be uniform, and the strength index should meet the requirements. During the printing process, the uniformity of the printing pressure is closely related to the thickness of the self-adhesive label. If the thickness is uneven, the printing pressure cannot be kept consistent, which may cause the writing or ink color of the label printed matter to appear in different shades. At the same time, the rewinding tension of the film should be uniform and moderate. If the tension is too small, the film substrate will be loose, which may lead to inaccurate overprinting in the vertical and horizontal directions; Normal printing.

In addition, the self-adhesive label should also have good corrosion resistance, aging resistance, no fading, and a small shrinkage and expansion ratio. If the corrosion resistance is poor, it is easy to age, and fades, the resulting label will not be able to meet the needs of long-term use, which will adversely affect the sales and use of commodities.

Finally, the self-adhesive labels you choose should be within the validity period and maintain good adhesion. In the process of label use, we should pay close attention to the above points to ensure the quality and use effect of the label.
