Fruits can supplement us with dietary fiber, vitamins, trace elements, etc. Perhaps many people did not expect that fruits can also be marked with a laser marking machine. It's amazing, how is this done? How does it work?
In the fruit market, some imported fruits or local fruits with certain brands, in order to highlight the brand awareness, will put a label on the surface of the fruit, indicating the brand, origin and other information. However, this kind of label is easy to be torn and forged. The use of laser marking machine to mark on the peel will not only not damage the pulp inside the fruit, but also play an anti-counterfeiting effect. This method is unique and innovative.
How Does A Laser Fruit Marking Machine Work?
Most fruits have a waxy layer on the surface, underneath the waxy layer is the peel, and under the peel is the pulp. After being focused, the laser beam penetrates the waxy layer and interacts with the pigment in the peel to change its color. At the same time, the water in the peel evaporates to achieve the purpose of marking. The laser marking machine only discolors the peel without damaging the pulp and waxy layer, so the marked fruit can be stored for a long time without decay.
The fruit label laser marking technology uses laser to mark information such as logo, sign, PLU code, QR code and barcode on the surface of coconut, citrus, melon and pomegranate. This marking information improves the difference between the laser marking part of the fruit and other parts, making the "fruit label" easier to read. The fruit label eliminates the need for paper, ink and glue used in traditional labeling.
Laser marking machines are widely used in a series of metal and non-metal products such as electronic components, stainless steel, auto parts, plastic products, all of which can be marked with laser marking. The best model for laser marking on fruits is a carbon dioxide (CO2) laser marking machine. Marking on fruits is novel and unique, energy-saving and environmentally friendly, and is worthy of promotion.
