UV laser marking tea packaging bag production date QR code
RFH 355nm UV laser for non-contact marking of tea packaging QR code
High-speed marking of plastic packaging bags by solid-state nanosecond ultraviolet laser
At present, many tea packages on the market have product QR codes. After buying tea, many people will scan the QR code on the package with their mobile phones to learn about relevant information and trace the source of the product. But everyone knows how the QR code does it. Is it on the bag?
More and more two-dimensional codes on the market are printed by UV laser marking machines. Compared with ink jet printers (inkjet machines), UV laser printers have very big advantages, with higher resolution and stroke by stroke. More regular, compared with the dot matrix font, it makes people feel better at first glance, and the grade has been improved to a certain extent. At the same time, after reacting with the plastic material of the bottle itself, the laser coding will be better. The color contrast is clear, and the date, expiration date, batch number, etc. can be seen clearly. 355nm UV laser can be used for UV marking.
The 355nm UV laser is developed and produced by RFH Company. As a top laser manufacturer, the 355nm all-solid-state UV laser developed and produced by RFH Company adopts a unique laser cavity design, acousto-optic Q-switching technology and high-precision cooling system, and is small in size. High integration; pulse width <20ns@40k, so the processing heat-affected area is very small; superior beam quality (M2<1.2), strictly guaranteed in all frequency ranges; perfect spot characteristics (spot ellipticity>90%). These parameters can remain consistent under extreme conditions in industry and scientific research.
RFH This 355nm all solid-state UV laser just has both marking quality and marking efficiency. The integrated design makes it convenient for manufacturers to integrate equipment to suit various laser application control needs. It has a fully digital intelligent power control technology independently developed by RFH's professors and doctoral-level R&D team, which can update the power control system functional modules in time, and improve the functional modules according to the laser requirements to maximize the performance of the equipment. Moreover, it supports communication with a computer, and can control the laser externally through RS232 to meet the needs of automated processing and production. Its excellence is all-round.
RFH has worked hard for 13 years, and has achieved one after another first-class nanosecond lasers, which has won high recognition and good reputation from users in all walks of life, and has made important contributions to my country's efforts to become a powerful industrial manufacturing country.
