AI Overview
Nanosecond UV lasers provide high-contrast, permanent marking on food packaging—including flexible films, plastics, and cardboard—without inks, solvents, or surface damage. Using a "cold marking" photochemical process, they create precise, legible codes (date, QR, barcodes) that are sustainable and tamper-proof. This method eliminates consumables, improving efficiency and reducing waste.
Key Benefits of UV Lasers for Food Packaging:
- Cold Marking Technology: UV lasers (typically 355 nm) break molecular bonds rather than burning, preventing heat damage to sensitive packaging materials.
- High Contrast on Materials: Effective at marking flexible films, plastics, and coatings by causing a chemical reaction with pigments like titanium dioxide.
- Sustainability & Cost Reduction: Eliminates the need for traditional inks, ribbons, and consumables, resulting in lower operational costs and reduced environmental impact.
- Permanent and Traceable: Creates indelible marks resistant to fading or rubbing off, enhancing food safety and traceability.
- Superior Quality: Enables fine, high-resolution printing for complex logos, 2D codes, and high-speed, point-to-point marking.
Common Applications:
- Flexible Packaging: Expiration dates, lot numbers, and barcodes on food pouches.
- Direct-on-Food Marking: Laser marking fruit, vegetables, and chocolates without destroying the product surface.
- Sterile Packaging: Safe for use on dairy, beverage, and medical packaging due to the non-contact, cleaner nature of the technology.
UV laser systems, such as the KEYENCE FP-1000 Series or Domino U510, offer high-speed, low-maintenance marking to meet strict traceability regulations.
