The solution to the phenomenon of sticker labeling machine warping

The perfect visual effect should be achieved in the labeling. One of them is to avoid warping in labeling. Label the tube before it is filled, and then perform filling and sealing after the labeling. The heating during the sealing process is particularly severe for the label. The closer the label is to the bottom, the greater the possibility of warping the label. In practical applications, almost every manufacturer has similar problems, and there are various solutions:
(1) Increase the viscosity of the label and try to make the label stick firmly. To achieve this effect, the following aspects need to be considered:
①Improve the surface quality of the hose to be attached. Most of the products have varnish on the surface, which will increase the difficulty of labeling. The seepage of the contents, the micro-holes in the tube wall, etc. will cause the label to lift. How to avoid such problems should be considered by everyone. a rather important question.
②Control the labeling pressure of the label during the labeling process.
③Control the temperature during the labeling process. Increasing the labeling temperature will improve the labeling effect, because as the temperature increases, the activity of the material inside the object will increase, and the label will be easier to integrate with the tube body.
(2) Try to use soft label materials, and good label ductility will greatly improve the warping label.
(C), change the shape of the label.
Shape the bottom end of the label into an arc, avoiding the deformation area of ​​the end cap as much as possible. Of course, the arc should not be opened too deep, otherwise it will easily cause wrinkles due to the problem of the label itself, which will increase unnecessary trouble. For special-shaped end caps, the shape of the label is required to be changed accordingly, which can not only avoid warping the label but also increase the aesthetics.
(4) Eliminate the influence of static electricity.
The labeling process is prone to generate static electricity, which will have an impact on the labeling effect. Properly increasing the humidity at the labeling site will improve it to a certain extent. Using an ion fan is also an effective solution. The inside of the labeling machine is equipped with automatic humidity control, and the cleanliness of the inside of the equipment can be independently controlled, so that the labeling can be kept away from dust and the quality of product labeling can be improved. In this way, there is no longer the phenomenon of warping the label during the labeling process, and the visual effect is achieved.
