Dairy Industry

Reliable marking under dairy-specific conditions

Providing coding that keeps up with cold, wet and high-speed lines

Challenges in Dairy Industry

In dairy processing, packaging surfaces are often cold, moist, or uneven. These conditions can especially affect code adhesion and readability.
High throughput, frequent product changes, and strict hygiene requirements add complexity to marking operations.
Coding must remain consistent across materials like cartons, PET bottles, and foil lids, while fitting seamlessly into clean-in-place workflows.

Continuous Inkjet Printer

Continuous Inkjet systems are well suited for dairy environments. They deliver sharp, moisture-resistant codes even on cold or wet surfaces. The printers handle varying materials and product formats with minimal adjustments, supporting quick changeovers. Their robust design and unique Safe Clean Station make them a reliable choice in hygiene-critical areas.

CO2 Laser Coder

CO₂ laser coders produce high-contrast, permanent marks on common dairy substrates without consumables.
 
With no moving parts in the print process, CO₂ lasers offer high uptime in
dairy production.
 
For stable, high-volume formats, they deliver clean & elegant codes with minimal maintenance—ideal for dairies seeking long-term reliability and hygienic operation.

Vision System

Vision systems verify the presence, position, and quality of each code in real time. They help ensure compliance and reduce manual checks, especially when multiple SKUs are running on the same line. Integration into existing automation supports traceability and streamlines audits.
