HuiZhou StarColor Water Based Ink

【Product Overview】 This water-based gravure high-temperature resistant ink is a high-end environmentally friendly material specially developed for packaging under special working conditions. It uses a special modified resin with a high glass transition temperature to ensure that the ink film maintains excellent physical stability during high-temperature heat sealing or hot filling processes, without sticking, discoloration, or peeling. 【Main Application Scenarios】 Coffee Packaging: Coffee bean bags and drip coffee bags that require high-temperature heat sealing. Hot-filled Foods: Condiments, heat-sealed composite bags on automated packaging lines. Aluminum Foil Packaging: Chocolate, pharmaceuticals, and flexible packaging requiring heating. Retort Packaging: Food bags that undergo light retorting or pasteurization. 【Core Technological Advantages】 Excellent Heat Resistance: The ink layer can withstand instantaneous heat sealing temperatures of 180°C - 220°C without anti-blocking or ink shadowing. Superior Adhesion: Adhesion is strengthened for high-requirement substrates such as treated PET, nylon (BOPA), and aluminum foil. Color Stability: Utilizing heat-resistant pigments, the hue remains constant under high temperatures, without yellowing or fading. Extremely Low Solvent Residue: The pure water-based system ensures no chemical residue inside the packaging, fully complying with food contact safety and hygiene standards. Excellent Printability: Compatible with medium- and high-speed gravure printing machines, exhibiting excellent light-screen transfer and producing smooth and delicate results in large-area solid printing. 【Technical Parameter Reference】 Heat Resistance: ≥ 200°C (Heat-sealing test) Fineness: ≤ 5 microns Viscosity: 18-28 seconds (Zahn 4# cup) Drying Speed: Compatible with 150-220 m/min Production Line Packaging Recommendation: 20kg industrial-grade drum
