Laser marking of fruit and vegetables
LASER LABELLING OF FRUIT AND VEGETABLES
No need for labels or plastic packaging while maintaining flavour and shelf life. Environmentally friendly and productive: the laser labelling of fruit and vegetables requires no set-up time, improves the margin, and at the same time requires minimal resources.
A Natural Branding machine labels different fruit and vegetables – with no contact, in a natural way, and without the use of additives or chemicals.
Laser marking fruit and vegetables with EcoMark
Laser technology may not sound natural. Nevertheless our CO2 laser machines are the ideal way to brand organic fruits and organic vegetables for sale in supermarkets. For EcoMark Natural Branding removes only a micrometre-deep layer of the fruit or vegetable peel. The laser beam remains so close to the surface that fruit and vegetables are completely intact beneath their skin or peel. Shelf life is 100 per cent guaranteed. The natural flavour is also retained. And consumers can simply remove or eat the branding with the skin or peel. Our branding works without additives.
A highlight of EcoMark Natural Branding is our on-the-fly technology. Coordinated control software can put into effect practically any branding of items. Labels can be modified with just a few clicks. And because we even brand citrus fruits, we are taking Natural Branding into a new dimension in several respects.
Productivity in figures
Different laser strengths are available, and the machine can be fitted with a laser output of 30 W, or up to 120 W, depending on requirements. Consistent further development has enabled us to fit our machines with a fast 3D camera. Process times of 0.1 seconds per product are therefore possible, and up to 50,000 items can be laser marked per second.

THE ADVANTAGES OF NATURAL BRANDING

The natural packaging alternative
There is a simple insight behind the Natural Branding procedure: why do we have to look around for packaging alternatives when products already have the best packaging on them? Nature has designed each fruit or vegetable skin or peel precisely according to the storage requirements of a fruit or vegetable. There is essentially no difference between the hard shell of a coconut and the thinner protective layer of a cucumber. Both protect the inside of the fruit or vegetable from environmental effects, both ensure cushioning from impact damage in the growing environment, and both enclose the product perfectly from the exterior on all sides.
Besides this, every skin or peel on fruit or vegetables always consists of a coloured upper layer in which most of the pigments are to be found. These include more or fewer levels of colour which have their own protective function. From the perspective of branding, fruit or vegetable skin or peel is also a perfect surface for branding. In theory, a lemon has enough space for placing an organic seal prominently and visibly. An entire story could even be accommodated on a banana using the relevant branding device. The problem with these considerations before was how to permanently mark the skin or peel while not damaging the fruit or vegetable or altering it chemically, and without having to resort to additional means such as adhesives, colours or pigments. Natural Branding has found the answer. With this method of branding fruit and vegetables, a laser removes the topmost layer of pigment from the skin or peel according to computer-controlled specifications. This colour removal is carried out so precisely that logos, lettering and text can be marked permanently on a fruit or vegetable in an exact size and position within fractions of a second.
“Tattooed fruit” – Natural Branding as a packaging alternative
This form of branding foodstuffs is something like reverse tattooing: Instead of adding colour, the colour is taken away from the peel. This creates a negative that is clear in terms of legibility and contrasts. It is possible because the uppermost layer of peel always contains the highest concentration of colour pigments. The laser focuses exclusively on this layer, so that the parts of the product underneath it are not affected. The skin or peel thereby contains the same protective function that it would have without Natural Branding. No additive – let alone plastic – is required in any single branding stage of this process. Nor is any form of packaging necessary afterwards. Ultimately, ecological products with a branded organic label are clearly recognisable as such and are distinguishable from the conventional products in the supermarket.
