How to choose self-adhesive label？
The self-adhesive label should be flat, and the rewinding tension should be even. The flatness is good, and it can be conveyed, run, registered and rewinded correctly during printing. The rewinding tension of the film should be uniform and appropriate. If the tension is too small, the film substrate will be loose and the vertical and horizontal registration will not be accurate; if the tension is too large, the substrate will shrink in the horizontal direction, the color registration will be unstable, and it will be difficult to print normally.
Film type adhesive labels should also have the characteristics of corrosion resistance, aging resistance, non-fading, and small shrinkage and expansion ratio. If the corrosion resistance is poor, it is easy to age and fade, the label will not be durable, and it will also affect the sales and use of the product. If the shrinkage and expansion ratio is large, it will not only affect the overprint accuracy during printing, but also deform the label during use, which will affect the sales and use of the product. Especially for the labels of high-end products, try to avoid the embarrassing situation that the products have not expired and the labels are aging (label aging includes plastic aging and ink fading). When necessary, the aging resistance test of the plastic or label should be carried out to test its performance.
