UV laser source marking of food and drug packaging materials

With the continuous progress of society, people's awareness of food and drug safety has also been continuously improved. The paintable modification of the production date of the product has always been criticized by the general public. Many food and drugs are returned to the furnace after the expiration date and the production date is changed before they are put on the market. The practice of small workshops has also caused many large factories to suffer injustice. The application of UV laser marking in the food and drug industry makes it impossible to alter the production date of food and drugs. It not only makes food and medicine safer, but also makes consumers more trustworthy in the manufacturer. Let's follow the editor of Shangtuo Laser to learn about the UV laser marking machine.

Features of UV laser marking machine

1. Ultraviolet laser is a cold light source, and the thermal impact is particularly small during laser cutting or marking, and it is more suitable for deep processing of materials that are sensitive to thermal impact.

2. Ultraviolet lasers have narrower pulse widths and higher peak powers. Materials with higher damage thresholds such as ceramic sapphire can easily break through their damage thresholds, so it is easy to process polymers with high damage thresholds. Material.

3. The light spot after the UV laser is focused can reach a minimum of 15UM, so it is very suitable for micro-hole drilling processing. Laser processing principle: The laser marking machine uses a high-energy density laser beam to locally irradiate the workpiece surface, so that the surface material rapidly vaporizes or changes color, thereby exposing the deep material or causing the chemical and physical changes of the surface material to engrave traces, or They all burn off part of the material through light energy, showing the graphics and text that need to be etched.

4. It is pumped by American light wave laser, and the 355nm wavelength laser is output by 3 times of frequency doubling in the optical resonator. The electro-optical conversion efficiency is high and the beam quality is TEM100 mode.

5. Ultraviolet laser is a cold light source, with a small heat-affected zone and excellent beam quality to create ultra-high-precision marking effects.

6. The imported scanning head is adopted, the marking speed is fast, and it is suitable for micro-cutting and drilling at the same time.

7. Ultra-high peak power and very little thermal effect, it is very suitable for drilling and cutting of alumina and zirconia ceramics. The plastic shell does not damage the surface permanent mark and replaces the silk-screen effect.

8. The laser is maintenance-free for 20,000 hours, no consumables, low cost of use, power saving and energy saving

9. Integrated modular design, easy maintenance and small size

10. The marking is environmentally friendly and complies with ROHS standards.

11. The software can receive DXF, PLT, BMF, AI, JPG and other formats, and can automatically generate serial number and production date, barcode, QR code.
