Natural trademarks-the application of laser marking in agricultural products

In recent years, people have begun to choose healthy, natural, and ecological green foods, and the organic food industry has therefore ushered in a period of rapid growth. Eosta is a global distributor of fresh organic vegetables and fruits. The company will make their products unpackaged and labelless.

The Dutch began to use CO2 lasers to print labels on their fruits and vegetables, and then transport them to various shops. This natural label is a non-contact, environmentally friendly marking method.

The nature of this label is that this process does not have any materials added, which is essentially different from laser tattoos and fruit tattoos that require ink. The use of lasers will not produce new chemicals, nor will food rot or be contaminated. A low-power CO2 laser will only engrave the desired pattern on the outermost skin of the food by removing the pigment of the target itself.

"These laser-labeled fruits and vegetables taste like ordinary ones, they are absolutely safe and completely organic," said Michaël Wilde, manager of Eosta's Public Relations and Sustainability Department.

Although natural trademarks made with lasers are still a relatively new concept, companies like Eosta are already using such laser-engraved trademarks to distinguish organic products from traditional products, eliminating the use of stickers and packaging.

"The law requires us to distinguish between organic products and inorganic products, and this is what we are doing," Wilde said. "In our opinion, the unpackaged packaging of fruits and vegetables is a trend, and this is the future."

For labels of the same size, the CO2 emissions produced by laser marking are less than 0.2% of the CO2 emissions produced by the production of a sticker paper.

Wilde told the media that the feedback from consumers has been very good, and they have even requested that laser marking be used on other products.

"We currently supply this kind of products with natural trademarks all over Europe, and we are a bit surprised by the positive feedback from the market," he said. "We received inquiries from bakeries and oyster dealers, and I also saw this application being used to mark holiday products for Valentine's Day, Christmas and Halloween, so I think this application is still very broad."

Wilde added that he is seeing more and more foods use laser marking instead of packaging, because people are looking for more sustainable methods that can replace plastics.

Eosta uses laser marking products such as avocados, sweet potatoes, mangoes and apples. Laser marking avoids the use of plastic and other packaging materials, only the avocado. The company said it will reduce the use of 750,000 plastic packaging bags this year.

Daily department store retailer ICA Sweden has introduced Eosta's natural laser marking in their production of organic avocado and sweet potatoes. Each product is printed with the product name, country of origin and PLU code.

"In this way, organic products do not need to be placed separately from other products," said Peter Hägg, head of ICA Sweden's vegetable and fruit series. "Since each product is engraved with a label, there is no need for stickers, trays or cellophane anymore. The overall effect is very good."

Natural trademarks have become a classic case of using laser marking in organic products. It is very suitable for use in organic foods, as a simple, attractive and sustainable way to replace plastics and stickers. In the product, not in the land.
