1. Use soft label materials as much as possible, and good label ductility will greatly improve the warping.
2. Change the shape of the label
Make the bottom end of the label curved, and try to avoid the deformation area of ​​the sealing tail. Of course, the arc can not be opened too deep, otherwise it is easy to cause wrinkles due to the problem of the label itself, adding unnecessary trouble. For the special-shaped tail seal, the shape of the label needs to be changed accordingly, which can not only avoid the lifting of the label, but also increase the beauty.
3. Eliminate the effects of static electricity
The labeling process is prone to static electricity, which will affect the labeling effect. Properly increasing the humidity at the labeling site will improve to some extent. The use of ion fans is also an effective solution. There is automatic humidity control inside the labeling machine, which can also independently control the cleanliness inside the equipment, keep the label away from dust, and improve the labeling quality of the product. In this way, the labeling process no longer has the phenomenon of warping and achieves the visual effect.
4. Increase the viscosity of the label and try to make the label stick firmly. To achieve this effect, it needs to be considered from the following aspects:
â‘ Improve the surface quality of the attached hose. Too much varnish on the surface of most products will increase the difficulty of labeling. The leakage of the content, the micropores in the wall of the tube, etc. will cause the label to warp. A more important issue.
â‘¡Control the labeling pressure of the label during the labeling process.
â‘¢Control the temperature during labeling. Increasing the labeling temperature will improve the labeling effect, because as the temperature increases, the activity of the internal substance of the object will increase, and the label will more easily merge with the tube body.
