British retailer marks & spencer has introduced a new laser marking method to mark avocados in the hope of reducing paper waste. From the use of paper sticky labels to laser printing, you can save 10 tons of label & backing paper and 5 tons of adhesive each year.

Avocados were harvested from the country of origin and graded according to their origin, and then shipped to England. After arrival, the mature avocado is placed in the tray and sent to the conveyor belt, and then the information is marked with a laser.

The laser marking will print the retailer's logo, the best date of consumption, the country of origin and the encoding of the silver in the outer layer of the avocado. M&S claims that the intensity of the light hitting the outer skin of the fruit will only make the skin off the outermost layer, which is not destructive to the fruit, and can be very precise.

"Given the success of all the practices on the avocado, we can extend the laser label technology to all kinds of other fruits and vegetables," said fruit technologists. It is very exciting that we will have the opportunity to reduce packaging waste at an exponential rate."

And this kind of label easy to tear or fraud, laser marking technology can be conducted on the skin, not only won't destroy the inside of the fruit pulp, and can have anti-counterfeit effect, unique and has a new idea.
