Production Date Marking Machine for food packaging bags

Marking Machine for food packaging bags When purchasing food, consumers will always check whether the food packaging is overdue according to the production date life. Consumers also need to pay attention to the appearance and internal conditions of the food to judge whether the packaging is intact and so on. Therefore, when marking food packaging bags, it is usually necessary to select a suitable marking machine according to the material of the packaging bag. For UV laser marking machine, we use third-order intracavity frequency doubling technology. Compared with infrared laser, 355nm UV light has a very small focus spot, which can reduce the deformation of the material to a large extent. Apart from that, it also has very small heat effect in processing, so it is mainly used for ultra-fine marking and engraving, especially suitable for food and pharmaceutical packaging materials, micro-hole drilling, high-speed division of glass materials and complex pattern cutting of silicon wafers and other applications.

UV marking features: (1) The UV laser marking machine adopts a kind of cold processing, so the fineness and thermal influence are minimized, and it is suitable for marking various fine markings, especially food packaging bags. (2) When using cold laser processing, the probability of material influence is reduced to one percent.
