Taboo 1: Direct Contact with Hydrophobic Substrates Technical LimitationsWater-based inks use water as a solvent, featuring high surface tension (typically >40 mN/m), making them difficult to wet non-polar polymers like PE and PP. Direct printing often results in insufficient adhesion (cross-cut test <3B) and ink film shrinkage. For untreated PE films, adhesion test results often…

Against the dual backdrop of global carbon neutrality goals and the booming e-commerce economy, the corrugated packaging industry is undergoing profound technological transformation. As a cutting-edge technology in printing, water-based inkjet has revolutionized environmental standards and production efficiency, reshaping industry competition dynamics. This article delves into the core advantages, practical applications, and future development trends…

I. Compatibility of Water-Based Inks with Screen Printing Screen printing’s adaptability to water-based inks is validated through optimized parameters and environmental benefits: ‌Mesh permeability‌: ≥85% on 400-mesh nylon screens at 25°C, comparable to solvent-based inks. ‌Viscosity‌: 12,000–18,000 cps (rotational viscometer, 25°C) ensures smooth ink transfer. ‌Surface tension‌: 32–38 mN/m balances substrate adhesion and mist control.…

I. Industry Trends and Environmental DemandAs global environmental regulations tighten (e.g., EU REACH, US EPA standards), traditional solvent-based inks are being phased out due to high VOC emissions and toxicity. Water-based inks, renowned for their low pollution and non-toxic properties, are emerging as the mainstream choice in the printing sector. Market data reveals the global…
