precision uv laser marking source for paper packaging box marking

In our daily life, products using paper packaging boxes are everywhere, such as toothpaste boxes, medicine boxes, biscuit boxes, high-end gift boxes, liquor packaging boxes, etc. The application scenarios are very rich, and the packaging of glass, plastic, metal, etc. Compared with materials, paper packaging boxes have natural advantages such as low cost, low processing difficulty, strong plasticity, easy recycling, and degradability.

In order to improve product identification, anti-counterfeiting, traceability and other functions, it is inevitable to mark the surface of the paper packaging box with graphic information such as the product's logo, product batch number, production date, etc.

Compared with traditional marking methods such as ink coding and sticking of self-adhesive labels, laser marking marks are permanent and are not easy to be erased and tampered with. Clean, no consumables, more energy saving and environmental protection. Its principle is that when the laser beam acts on the surface of the paper packaging, the high energy density makes the surface material evaporate instantly and expose the deep material, thereby engraving exquisite logos, texts, patterns, dates, batch numbers, or one-dimensional, two-dimensional mark.

The RFH 355nm UV nanosecond solid-state laser provides manufacturers with a low-cost, high-efficiency marking solution that enables high-quality and long-lasting marking in a short period of time.

The 355nm UV laser it outputs is a cold light source, with high single-photon energy and high absorption rate of paper materials, especially when the surface of paper packaging materials is covered with films, it is more difficult to produce scorching, curling and other phenomena; excellent beam quality (M2 <1.2), the minimum spot diameter after focusing can reach about 20um, the marking effect is delicate and clear, and even complex patterns can be easily marked; the pulse width of about 25ns makes the heat-affected zone small during marking, which is difficult for paper. For materials with similar low melting points, the degree of carbonization is minimal, and the marking is more beautiful.

In addition, the easy integration of the laser into the assembly line and the high flexibility of laser marking can make it possible to perform dynamic real-time flying marking on the paper packaging carton production line, marking the production date, characters and other complex patterns of the product. information.

Today, for paper packaging, the outer packaging of the product may directly affect consumers' desire to buy. By using laser to mark all kinds of clear and beautiful graphic information on the surface of the packaging box, and its efficient marking not only improves the efficiency of product packaging, but also enables the packaging box to obtain a powerful information traceability function, enabling quality monitoring and market circulation traceability more convenient.
