Sticker printing machine printing battery film label
The dry cell film adhesive label material is a material that can shrink and deform the surface material. With the characteristics of heat shrinkage, the printed label can be heated at both ends after being labelled on the automatic labeling machine. After the shrinkage deformation, the naked dry battery is wrapped in the middle to form a complete dry battery product.
Cell membrane adhesive printing machine processing methods are commonly the following methods: Flexographic printing method. North American and European label printing commonly used methods.
Generally use uv ink or alcohol ink. Before the film material is printed, corona treatment is performed to increase the surface tension. Surface coating can also be used to improve the ink fastness. Ask for glazing after printing to protect images and texts. Water-based inks should not be used to prevent ink layer from being loose. Gravure printing method. For printing on ordinary gravure presses, use solvent or uv ink. The printed sticker is first divided into small rolls by a slitter and then die-cut, discharged and rewinded on the processing machine. Finally, it is cut into a single roll on the dedicated slitting machine to prepare the labeling machine. Gravure reverse printing. For separate printing methods. First, a graphic is printed on the back of a special transparent PVC film, and then vacuum-plated on the surface of the graphic to cover the text.
In the second step, according to the adhesive material manufacturing process, the printed and aluminized PVC film is used as the material to manufacture the battery-specific adhesive label material. Finally, the entire process of label processing is completed on a label processing machine and a slitter after coating the processed large-volume battery film. Print coating method. Special process. After printing on PVC film, laminate a layer of PVC film on the surface.
Can use a variety of printing methods. It is required that the shrinkage rate of the coating material be the same as the shrinkage rate of the printed material, and the tension between the two must be consistent when the film is covered. Most people use dry compound methods to ensure quality and reduce costs. Usually, the thickness of the PVC printing material is 0.035 mm, and the thickness of the coating material is 0.015 mm. UV letterpress printing. Recently, it was widely adopted in China and Southeast Asia. a method. Due to the use of UV oil, the surface tension of the PVC material is required to be maintained at 38 dyn/cm or more, and the printed surface is finally treated with a glazing process to protect the graphic.
