What caused the problem of label warping when using the labeling machine? How to solve it?

        Although there are labeling machines with various performances on the market, it is always difficult to avoid various failures during use, such as label warping. This is a very common problem, especially In the labeling of self-adhesive labels, the problem of label warping is even more serious. Nowadays, many manufacturers are becoming more and more strict with the labeling machine labeling. The temperature rise may be accompanied by the entire process. If it is high, it will cause the affixed label to appear curled. When this happens, how can we effectively solve it? The following editor will give you an introduction:

1. The selection of adhesive used in label manufacturing is inappropriate. Regarding some products with a large surface curvature, the label should choose an adhesive with a large initial viscosity when selecting an adhesive. At the same time, the label paper of the labeling machine should not be used for thicker or harder materials, and thinner materials, such as films, thin soft paper materials, etc., should be used. As for products that require a process that may be heated, the selected label material advocates a film type and an adhesive with good initial adhesion.

2. Insufficient pressure of the label-applying wheel leads to the label not being completely adhered to the surface of the product.

Solution: Control the temperature difference in the labeling process and increase the temperature of the label in advance, so that the heating process in the production process of the labeling machine may require heating. After the temperature rises, the effect of the temperature difference before and after the attached label is reduced. Of course, increasing the labeling temperature can also increase the active substance on the object, so that the direct adhesion between the label of the labeling machine and the product can be improved. When selecting label raw materials, try to use softer materials as much as possible. Improving the malleability of the label can effectively improve the problem of label warping.
