Labeling machine for labeling to be in perfect visual effect. One of them is to avoid the phenomenon of tilting in the labeling. The label is applied before the tube is filled, and the filling and sealing are performed after the tube is attached. The heating of the label in the sealing process is particularly severe, and the closer the label is to the bottom end, the more likely the label is. In practice, almost every manufacturer has similar problems, and the solutions are also diverse:
(1) Increase the viscosity of the label and try to make the label stick firmly. To achieve this effect, we need to consider the following aspects:
1 Improve the surface quality of the attached hose. Most of the products have varnish on the surface, which will increase the difficulty of labeling, the leakage of contents, the micropores of the tube wall, etc., which will cause the label to rise. How to avoid such problems should be considered by everyone. A more important issue.
2 Control the labeling pressure of the label during the labeling process.
3 Control the temperature during the labeling process. Increasing the labeling temperature will improve the labeling effect, as the activity of the internal material will increase as the temperature increases, and the label will be more easily integrated with the tube.
(B), try to use soft label materials, good label ductility will also greatly improve the warping label.
(3) Change the shape of the label.
Make the bottom end of the label curved and try to avoid the deformation of the seal. Of course, the arc cannot be opened too deeply, otherwise the wrinkles are easily caused by the problem of the label itself, which increases unnecessary trouble. For the special type of sealing, the shape of the label is required to be changed accordingly, so that not only the tilting can be avoided but also the aesthetics can be increased.
(4) Eliminate the effects of static electricity.
The labeling process is prone to static electricity, which will have an impact on the labeling effect. Appropriate improvement of the humidity at the labeling site will result in some improvement. The use of an ion fan is also an effective solution. The labeling machine is equipped with automatic humidity control inside, which can separately control the cleanliness inside the equipment, keep the label away from dust and improve the labeling quality of the product. In this way, there is no longer a phenomenon of tilting in the labeling process, and the visual effect is achieved.
