Food packaging is not just a protective layer but a vital medium for communicating with consumers through intricate designs. However, traditional inks pose significant risks in food packaging, including residue migration, chemical leaching, and color fading after high-temperature sterilization. Zhongzhixing’s specialized water-based ink for food packaging addresses these challenges head-on. Built on the core values of “zero migration, full compliance, and extreme durability,” it ensures healthier packaging, passes stringent safety tests, and aligns with brands’ commitments to consumers, establishing an impenetrable line of defense for food safety.

1. Safety Revolution: Eliminating Contamination at the Source

Direct contact with food demands absolute ink safety. Zhongzhixing adheres to food-grade R&D standards to deliver reliable solutions for food packaging.

• Zero Migration Pledge: Using ultra-low molecular weight resins and inert pigments, Zhongzhixing eliminates the risk of harmful substance migration. Migration levels are far below China’s GB4806.14-2023 standards. Even under extreme conditions like exposure to oils or acidic liquids, no substances leach out, ensuring total consumer safety.
• Global Compliance: The ink meets rigorous certifications, including FDA 21 CFR 175.300, EU 10/2011, GB4806, and ISO 22000 food safety management systems. These credentials unlock access to global markets (EU, North America, RCEP), empowering brands to expand worldwide.
• Zero Harmful Substances: Free from benzene, plasticizers, heavy metals (lead, cadmium, mercury), and other toxins, Zhongzhixing’s ink ensures traceability from raw materials to production, guaranteeing the highest safety standards.

2. Technological Excellence: Conquering Four Extreme Challenges in Food Packaging

• High-Temperature Sterilization Resistance: Withstands 120°C sterilization for 30 minutes, maintaining color stability (ΔE <1.5). This breakthrough solves color fading in labels for liquid milk, canned goods, and other products requiring high-temperature processing.
• Oil Resistance: For oily foods like cooking oils and sauces, Zhongzhixing’s patented “molecular lock” structure prevents ink swelling or peeling. Passes ASTM F719 testing after 72-hour oil immersion, ensuring packaging longevity.
• Freeze-Thaw Stability: Survives 50 cycles of -30°C freezing and thawing without cracking, safeguarding frozen food packaging during cold-chain logistics and storage.
• Humidity Resistance: Maintains integrity in 95% humidity for 30 days—no adhesion or mold growth—ideal for tropical climates and challenging storage environments.

3. Full-Scenario Protection: From Fast Food to Premium Packaging

• Liquid Food Packaging: Milk cartons, juice pouches, and similar products retain vibrant colors post-pasteurization. Migration levels meet infant food-grade standards, offering unparalleled safety.
• High-Fat Product Packaging: Prevents ink “bleeding” in oily environments (e.g., hotpot seasoning bags, nut packaging), ensuring aesthetics and cleanliness even during long-term storage.
• Microwave-Safe Labels: Withstands 130°C instant heat, keeping pre-made meal tray labels odor-free and intact after microwaving, combining convenience with safety.
• Premium Gift Boxes: Combines tactile varnish and anti-counterfeit inks for chocolate boxes, wine labels, and luxury packaging, enhancing safety while delivering opulent visuals and brand value.

Why Choose Zhongzhixing?

• End-to-End Solutions: Offers “ink + printing process + compliance certification” services, delivering pre-compliance test reports within 3 days. This streamlined approach saves time and costs.
• Cost Efficiency: Reduces VOC treatment expenses, lowering total printing costs by 30%. High ROI and cost-effectiveness make it the top choice for food packaging printers.
