Fruits Get Laser Tattoos To Replace Sticky Labels
Spanish company Laser Food has created a machine that is able to apply laser logos to fruits.
Tattoos in the form of barcodes, logos, or QR codes can be used to mark the fresh produce—and 54,000 fruits can be branded within an hour.
To brand the fruits, however, chemicals of iron oxides and hydroxides are used on the skin—to make the laser markings more obvious and avoid the laser from penetrating the skin of the fruit, according to Dezeen.
The plus point of ‘tattooing’ the fruits is that it reduces the use of paper, plastic and glue in stickers; the fruits would also be sold with its supply chain details.
