The Sustainability Imperative
Packaging brands face pressure from consumers, retailers, and regulations to reduce environmental footprint. Flexo printing offers multiple pathways to significantly reduce impact while maintaining quality and efficiency.
Water-Based Inks
Modern water-based flexo inks match solvent inks in color intensity, adhesion, and rub resistance on most substrates. VOC emissions drop 90–95%, eliminating explosion-proof installation requirements and simplifying compliance. LISHG's extended hot-air drying achieves complete evaporation at 200–250 m/min.
LED UV Technology
LED UV replaces mercury arc lamps: energy consumption drops from 5–10 kW to 1.5–3 kW per unit, lamp life increases from 1,500 to 50,000 hours, no mercury disposal, no ozone generation. Annual energy savings: €15,000–25,000 per machine.
Heat Recovery Drying
LISHG heat exchanger ovens recover 60–70% of drying heat from exhaust air. For an 80 kW drying system, that's 48–56 kW recovered — approximately €40,000/year in energy savings in European markets.
