At present, the mainly package for milk product include Tetra Pak, roof boxes, sterile plastic bags, yogurt cups, PET polyester bottles, glass bottles, etc. Almost all dairy product packaging can be coded by CIJ inkjet printers. In recent years, with the national top manufacturers development, they have taken the lead in coding their high-end dairy products, use UV Laser marking machine to replace inkjet printer. For example roof box yogurt, PET polyester bottled yogurt and other products. At the same time, the other dairy manufacture follow up and replaced the CIJ inkjet printer too.
Use UV laser printer to replace inkjet printer on dairy products is more determined by the marking quality and aesthetics of the production date. The production date must be clear, accurate and cannot be modified before the consumer. Compared to inkjet printer, UV laser coding inherently meets this requirement. Because uv laser coding machine use laser beams to permanently change the material composition of the surface material of the packaging and show a different color from the substrate, no ink is required throughout the process. Or carbon ribbon, there is no substance attachment, but the packaging material is directly modified, so that the printing effect will never disappear without the packaging being damaged; Another important reason is the beauty: the point with the ink printer the array coding is different. The UV laser printer's printing effect is the same as the font displayed on books and computer screens that people come into contact with daily. In addition, the laser printing lines are fine and contrast. UV laser coding further enhances the grade and brand image of the product;
And the dairy products packaged by PET Bottles should coded message on the caps, No matter what the bottle cap color and material (usually PP or HDPE material) selected by the dairy manufacturer, the CYCJET UV laser printer can make Part of the material undergoes a photochemical reaction that causes discoloration, forming a high contrast, so the consumer can read message easily, and never fading the production date code. Therefore, at the same line speed, the UV laser printer can use a lower power to meet the coding requirements, thereby extending the life of the laser. If you also need to code on PET polyester bottles, It can be equipped with a carbon dioxide laser printer in the 9.3 micron band.
At present, the general Tetra Pak products can be stored at room temperature, and the product positioning is usually not high. Therefore, the main coding method for the Tetra pak still CIJ Inkjet printer, because it can reduce more cost. If you need to choose laser coding, you can use CO2 Laser marking machine, the overall investment cost of CO2 Laser coding machine is much lower than that of UV laser printer, and it can also provide permanent and unchangeable laser coding effects. Each dairy product manufacturer may need to redesign the packaging to suit CO2 laser printer coding method, please call Shanghai Yuchang Industrial Co., Ltd. for more solutions;
In summary, Laser marking machine can be used as an alternative to ink printers on various packaging of dairy products, providing permanent, clear, beautiful and unchangeable production dates and batch coding for dairy products. UV laser marking machine has completed replaced the inkjet printers in the field of coding of high-end dairy products. However, the process of using laser coding technology to replace ink coding machine in the dairy industry has just begun. Dairy Industry Food Safety Makes Greater Contribution!
