Natural trademarks - laser marking in the use of agricultural products

  In recent years, people began to tend to choose health-friendly, natural, eco-friendly green food, organic food industry thus ushered in a period of rapid growth. Eosta is a global distributor of fresh organic vegetables and fruits that will make their products unpackaged and unlabeled.

  The Dutch started labeling their fruits and vegetables with CO2 lasers and shipping them to stores. This natural label is a non-contact, environmentally friendly marking method.

  The beauty of this label is that the process does not have any material added, which is essentially different from the need to use laser tattoos and fruit tattoos. The use of lasers does not produce new chemicals nor does it spoil or contaminate the food. A low-power CO2 laser simply carves out the desired pattern by removing the target's own pigment on the outermost skin of the food.

  "These laser-tagged fruits and vegetables taste exactly the same as ordinary ones and are absolutely safe and completely organic," said Michaël Wilde, PR and Sustainability Manager at Eosta.

  Although natural marks made with lasers can be a rather trendy concept, companies like Eosta are already using the laser-engraved label to differentiate organic products from traditional ones, eliminating the need for stickers and packaging.

  "The law requires us to distinguish between organic and inorganic products, and that's what we are doing," Wilde said. "In our view, the unpackaged vegetable and fruit packaging is a trend and this is the future."

  For the same size label, laser marking produces less than 0.2% of the CO2 emissions from producing a single sheet of paper.

  Wilde told the media that consumers responded very well and they even asked for laser marking on other products.

  "We currently have this natural-brand-based product available throughout Europe, and we're a bit surprised at the positive feedback from the market," he said. "We got inquiries from bakeries and oysters and I also saw that this app was used to mark festive products for Valentine's Day, Christmas Day and Halloween, so I think the app is still very broad."

  Wilde added that he sees more and more food using laser marking instead of packaging as people are looking for more sustainable ways to replace plastic.
  Eosta laser marking products such as avocado, sweet potatoes, mango and apple. By laser marking to avoid the use of plastic and other packaging materials, just a piece of avocado, the company said it will reduce the use of 750,000 plastic bags this year.

  ICA Sweden, a regular department store retailer, has introduced Eosta's laser natural marking to their organic avocado and sweet potato production steps, each bearing the product name, country of origin and PLU code.

  "This way, organic products do not need to be placed separately from other products," said Peter Hägg, head of ICA's portfolio of fruits and vegetables. "Since there is a sticker on every product, there's no need for a sticker, tray, or cellophane, and the overall effect is great."

  Natural mark has become a classic case of laser marking in organic products, it is very suitable for use on organic food, as a simple, attractive and sustainable way to replace the plastic and the sticker one by one into the label In the product, not in the land.
