Futonics thulium fiber lasers are suitable for gentle, contact-free marking of foods such as fruit, vegetables, cheese, meat and sausage products. In natural branding, the marking is applied directly to the surface of the product without stickers, inks, films or adhesives.

Laser marking of foods enables clearly readable, durable markings without affecting product quality or shelf life. With Futonics 2 µm lasers, the surface can be marked precisely while the pulp, flesh or product contents remain unaffected. This makes the process particularly suitable for applications where hygiene, sustainability and traceability are essential.

Sustainable alternative to labels and packaging films

Conventional food labeling methods often use stickers on fruit and vegetables or additional plastic packaging. These methods generate paper, plastic and adhesive waste and may require additional process steps in packaging and logistics.

Natural branding with Futonics lasers reduces the use of labels, plastic packaging and adhesives. The marking is applied directly to the peel or surface of the food product. This allows product information, logos, codes, brand markings, origin data or best-before dates to be applied without additional consumables.

Why 2 µm thulium fiber lasers are suitable for food labeling

In laser food labeling, controlled and locally confined energy delivery is essential. The marking must be clearly visible without affecting the quality, shelf life or edible parts of the food. Futonics thulium fiber lasers in the 2 µm wavelength range enable precise surface processing and are suitable for gentle marking processes on various foods.

The contact-free process is clean, hygienic and reproducible. Since no labels, inks or adhesives are used, the food does not come into contact with additional chemical consumables. At the same time, markings can be produced quickly and with low energy consumption.

Typical information for laser marking

Laser marking of foods can include many types of information that are traditionally printed on labels or packaging.

Typical markings include:

• Logos and brand markings
• Origin information
• Batch numbers
• Product codes
• QR codes or Data Matrix codes
• Best-before dates
• Organic or quality labels
• Traceability information

Suitable foods

Futonics lasers can be used for various foods with suitable surfaces. The specific suitability depends on the product type, peel, surface, moisture, desired contrast and process parameters.

Typical foods include:

• Fruit with peel, such as apples, oranges, bananas or avocados
• Vegetables, such as eggplants, potatoes, pumpkins or cucumbers
• Cheese with rind or a suitable surface
• Meat and sausage products with markable surfaces
• Other foods with suitable peel or outer structure

Advantages of food labeling with Futonics lasers

• Contact-free marking without mechanical stress on the food
• No stickers, inks, films or adhesives required
• Reduction of paper, plastic and adhesive waste
• Gentle surface marking without affecting the product interior
• Clean and hygienic process without additional consumables
• Clearly readable markings for logos, codes and product information
• Suitable for traceability and sustainable product labeling
• Faster process compared with many conventional labeling methods
• Low energy consumption compared with conventional marking methods
• Easy integration into industrial packaging and sorting systems

Think Green: Less packaging through natural branding

Natural branding supports more sustainable food labeling by reducing or replacing labels, adhesives and plastic packaging. Especially for fruit and vegetables, direct laser marking on the peel provides an environmentally friendly alternative to conventional stickers and films.

By eliminating additional packaging and labeling materials, waste volumes can be significantly reduced. Depending on the scale of implementation, savings of up to 93,000 tons of waste per year may be possible. At the same time, important product information remains visible and traceable.

Technical consulting for laser food labeling

Whether a food product can be marked with a Futonics 2 µm thulium fiber laser depends on the surface, peel, product moisture, desired contrast, marking speed and requirements for shelf life and hygiene. Futonics supports you in evaluating your application and selecting a suitable laser module for industrial food labeling and packaging systems.
