UV Flexo Inks With Heat Resistance
Our water-based screen inks are specifically designed for paper screen printing, delivering sharp, crisp results while meeting the core needs of a wide range of printers, from commercial packaging manufacturers to DIY craftspeople. Unlike solvent-based paper inks, which can release irritating fumes and damage delicate paper fibers, our water-based formulas balance sustainability, print quality, and ease of use.

Product Introduction
✅ Extreme Temperature Resistance: Withstands -40℃ (frozen storage) to 200℃ (instant heat sealing) - no peeling, fading, or blistering. Passes 100+ cycles of -40℃→200℃ temperature shock tests .
✅ Food-Grade & Eco-Compliant: Meets FDA 21 CFR 175.300 (food contact) and EU 10/2011 (plastic packaging) - safe for direct food packaging (e.g., snack bags, ). Heavy metal-free (Pb/Cd/Hg <10ppm) and low VOCs (<5g/L).
✅ Strong Adhesion on Multi-Substrates: Bonds tightly to PE, PET, BOPP, aluminum foil, and recycled plastics - no primer needed for most materials. Adhesion strength ≥4B (ISO 2409), even after 72h immersion in hot water (60℃).
✅ Fast UV Curing & High Efficiency: Dries in 3-5 seconds under 80W/cm UV lamps - compatible with high-speed flexo presses (up to 300m/min). No solvent evaporation, reducing production downtime.
FAQ:
1: Can this ink resist 220℃ instant heat sealing (e.g., for coffee capsule lids)?
Yes-we offer a custom FH-220 version (220℃ max) for high-temperature heat sealing. It's used by Starbucks for coffee capsule lids, passing 220℃/2s heat tests with no ink peeling.
2: Do I need a special UV lamp to cure these inks?
No-compatible with standard mercury or LED UV lamps (80-120W/cm). For fastest curing (3s), use LED UV lamps (395nm wavelength) - we can provide lamp parameter recommendations for your press.
3: Is the ink compatible with water-based overcoats (for extra protection)?
Yes-all series work with water-based, UV-curable, or solvent-based overcoats. We recommend our matching UV overcoat (OC-100) for enhanced abrasion resistance (scratch test >1000 cycles).
4: Can you customize PMS colors for small-batch orders (e.g., 5kg)?
Yes-minimum custom color order is 5kg. Provide your PMS code, and we'll deliver a sample within 3 business days for color approval. Bulk orders (≥50kg) get 10% discount.
