Product Introduction
This product is StarColor® water-based flexographic ink specially developed for high-temperature packaging and printing scenarios. Using water as the dispersion medium, it boasts advantages such as environmental protection, low VOC, low migration, low odor, and non-toxicity. It is widely suitable for harsh application scenarios like high-temperature heat sealing, baking, and cooking bags, and can still maintain excellent color stability and adhesion during high-temperature treatment at 150–180°C. With food-grade safety certification and environmental protection characteristics, it not only safeguards consumers' health but also helps enterprises build a sustainable brand image.
Key Features
High Heat Resistance
Adopting an advanced heat-stable resin system, it maintains vivid colors and clear patterns after continuous treatment at 150–180°C for 30–60 minutes, preventing ink deformation, fading, or peeling. Compared with ordinary water-based inks, its thermal stability is improved by 40%, providing reliable protection for high-temperature processing packaging.
Food-Grade Compliance
Strictly adhering to international food contact material safety standards, it has passed FDA testing. From raw material selection to production process control, harmful substances such as bisphenol A and formaldehyde are eliminated throughout the process to ensure the safety of food packaging.
Eco-Friendly Water-Based Ink
Using water as the core solvent, the volatile organic compounds (VOCs) emission is nearly zero, far below the limits of the EU REACH Regulation and RoHS Directive. Free of heavy metals and harmful solvents, printing waste can be naturally degraded, helping enterprises meet global environmental regulations and reduce their carbon footprint.
Fast Drying & High Transfer
With optimized drying formulas and rheological properties, the ink cures rapidly in ordinary hot air or infrared drying equipment, with a 30% improvement in drying efficiency. Combined with precise flexographic printing processes, the ink transfer rate is as high as 95%, effectively reducing ink waste and improving production efficiency.
Excellent Print Sharpness
Through nanoscale pigment dispersion technology and polymer resin compounding, it maintains excellent printing clarity in high-temperature environments. Even for fine text below 0.1mm and gradient colors, it can accurately reproduce design details, avoiding pattern blurring or color bleeding caused by high temperatures.
