The label machine runs fast and stable, with high accuracy. It will not be damaged in the process of carrying the label, the label effect is good, and it is flat and does not wrinkle. The operation is simple, and only one person is required to operate it. It realizes automatic feeding, labeling and receiving, including lack of material detection electric eye and automatic pause function, and has strong flexibility.
When we use the label machine, what problems should we pay attention to in order to avoid label lift?
What should we notice when choosing the adhesive material of label machine?
What are the reasons for the omission of the label on the label machine and how can it be corrected?
Label warping is a very common phenomenon in label machines. The occurrence of label warping is often caused by the increase in temperature. In addition to temperature reasons, there are four reasons for label warping:
1. The stickiness on the label is weak, and the label cannot be firmly adhered to the product when the label machine is labeling.
2. Insufficient pressure of label machine covering wheel makes the label unable to completely adhere to the surface of the product.
3. The choice of label material is not suitable for the labeling of the product type. The selection of labels should be based on different types, materials, etc. to select materials. Softer products should use some relatively softer type labels. (If you don't understand, you can consult Gaozhen Machinery). Materials can choose PE, PVC, unstretched PP or PE, PP synthetic materials and so on. For harder products, the label material can be PET, PS, BOPP, etc.
The choice of adhesive used in label production is inappropriate. When using label machine, for products with larger surface curvature, adhesives with larger initial viscosity should be used. At the same time, it is not advisable to use thicker or harder materials for label paper. Instead, use thinner materials, such as films, thin soft paper materials, and so on. For products that need to go through a process that may be heated, the label material selected is preferably a film-type adhesive with good initial adhesion.
Self-adhesive label machine to solve the label-twisting phenomenon to achieve a perfect visual effect on labeling. One of these is to avoid the phenomenon of non-label when labeling. Label the tube before filling and filling and close the tube after labeling.The heating during the sealing process is particularly strong for the label. The closer the label is to the bottom, the greater the likelihood that the label will disappear. In practice, almost every manufacturer has similar problems and there are different solutions:
Increase the viscosity of the label and try to keep the label firmly attached. To achieve this effect, the following aspects must be taken into account:
Improve the surface quality of the tube to be attached to the label machine. The surface of most products is painted, making the label more difficult. The expiration of the contents, the microphones in the tube wall, etc. lead to the removal of the label. How to avoid such problems should be considered by everyone. A more important question.
Check the label printing the label during the labeling process using the label machine.
Check the temperature during the labeling process of the labeling machine. An increase in the labeled temperature improves the label effect as the activity of the substance inside the object increases with increasing temperature and the label is more easily integrated into the tube bodies.
As technology advances, label machine are increasingly used in everyday life. Dong Guan Do Hearts Technology Co.,Ltd is known for high precision label machines. And you can connect them.
