The self-adhesive label is a composite material, which is made of paper, film or other materials and coated with protective paper on the back. Compared with traditional labels, self-adhesive labels are widely used in the packaging field because of their cleanliness and time-saving labeling. In recent years, self-adhesive automatic labeling technology has developed rapidly and has become an indispensable part of packaging production lines. So, does the labeling equipment have requirements for self-adhesive labels? The answer is yes.
In actual operation, in order to realize automatic production, the label used by the self-adhesive labeling machine is generally a roll label, that is, it is wound on a paper tube. (Note: There is a gap between the labels, the gap is about 2-3mm). The material of the automatic labeling machine label can be customized according to the characteristics of the product, and it can also communicate with the labeling machine manufacturer according to the requirements of the applicable bottle type and labeling speed to achieve good results. A good self-adhesive label is not only beautiful, but also saves communication costs.
Precautions for self-adhesive labels: 1. It needs a certain thickness and hardness, otherwise it is easy to have unsatisfactory label coverage; 2. The label base paper needs to use glassine backing paper, which has good toughness and will not work when the labeling machine runs at high speed. 3. The printing direction of the label determines the positive and negative directions of the product label.
Classification and characteristics of self-adhesive label materials:
According to the classification and characteristics of self-adhesive label materials. Different materials are different in printability, transparency, tearability, softness, heat resistance, cold resistance, etc., so consider using self-adhesive labels. For example, when it is used as a commodity label in a supermarket, it is necessary to choose a self-adhesive label material with strong paper adhesion. Or the labels on the products in the freezer should be made of low-temperature-resistant surface materials.
According to the characteristics of the product surface substrate. Self-adhesive labels are used with the product. In order to make them play a greater publicity effect, we should fully consider the characteristics of the product's substrate or packaging material. For example, if the composition of the substrate is different, the ability to bond with the self-adhesive label will also be different. If the shape of the substrate is different, the required flexibility and stretchability of the label will also be different.
Transportation environment, temperature, humidity, temperature difference range, indoor or outdoor, whether there is direct sunlight, etc. These factors should also be considered when choosing self-adhesive labels. Although self-adhesive labels already have waterproof capability, their adhesion and firmness cannot be ignored.
If you want to choose high-quality self-adhesive labels, you need to consider the above three points. Besides, in the printing equipment and operation process, strict control and attention to detail are the direct factors that directly affect whether the self-adhesive sticker is good or not.
