Application problems and case analysis of sticker Technology

The progress of technology is inseparable from the demand of the market How to attract the attention of consumers with a wide range of consumer goods is the first problem to be solved by businesses All kinds of goods, especially consumer goods represented by daily chemical products, have higher and higher requirements for external packaging, so the labeling technology, which plays an important role in the external packaging, is changing with each passing day In self-adhesive labeling, it is easy to appear uneven labeling, bubble and wrinkle and low degree phenomenon Most of these problems are caused by the lack of proper labeling equipment and labeling materials according to the shape and materials of packaging containers The following will specifically introduce a case of double-sided labeling, and analyze how to solve the problems in labeling In the process of labeling, it is the ratio of the long axis to the short axis of the ellipse that is used to locate and label the product However, there are some special bottle types in this time The ratio of the long axis to the short axis of the cross section is close to "1", and the bottle is thin and high, which is easy to produce label tilt during labeling process, which affects the appearance Secondly, the surface of the bottle is pearlescent white, and a large number of pearlescent agent and mold release agent are added in the production process of the product, which will directly lead to the decrease of label adhesion and generate bubbles For the bubble problem of labeling, this example has made the following improvements: first, eliminate the influence of static electricity, use the de electrostatic ion fan to remove the static electricity of the bottle body, use the de electrostatic brush to remove the static electricity of the label; increase the labeling pressure of the label, try to increase the pressure to increase the adhesion between the label and the bottle; Control the labeling process, make the label contact with the bottle line in the labeling process, and thoroughly drive away the bubbles Through the above cases, it is not difficult to find that there are still several points that need to be solved thoroughly in the labeling process of the container: thin high products, because the labeling process is up and down clamping products, prone to product tilt imagination; products that are not easy to locate, simply rely on positioning mold labeling, reduce the production efficiency of the equipment; Hollow container, because the container is hollow, the increase of labeling pressure will make the surface of the container deformed, especially for the softer container, which can not increase the labeling pressure at all This article was / edited by
