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:
1. Improve the surface quality of the pasted hose. The surface of most products has varnish, which will increase the difficulty of labeling. The leakage of the content, the micropores in the tube wall, etc. will cause the label to lift. How to avoid such problems should be considered by everyone. A more important question.
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, because as the temperature rises, the activity of the substance inside the object will increase, and the label will be more easily integrated with the tube body.
Try to use soft label materials, and good label ductility will greatly improve label warping.
Make the bottom of the label into an arc shape, and try to avoid the deformation zone of the end seal. Of course, the arc cannot be opened too deep, otherwise the label itself will easily cause wrinkles and increase unnecessary trouble. For special-shaped end sealing, the shape of the label is required to be changed accordingly, which can not only avoid label warping, but also increase the aesthetics.
