In 2026, the global packaging and printing industry faces dual pressure: stricter food safety regulations and brand sustainability demands on one side, and increasing press speeds requiring superior drying, adhesion, and color performance on the other.

For years, many converters believed that switching to water-based ink meant sacrificing gloss or productivity. StarColor has changed that perception through advanced resin synthesis and formulation innovation. Today, our water-based flexographic inks are trusted across food packaging, labels, and flexible packaging applications.

1. Advanced Food Safety Protection

Food and pharmaceutical packaging leave no room for compromise. Solvent-based inks carry VOC concerns, while UV inks may present photoinitiator migration risks.

• Photoinitiator-Free Formula: Eliminates migration risks associated with UV systems.
• Regulatory Compliance: Conforms to FDA 21 CFR 175.300 and EU REACH SVHC standards.
• Low Odor Technology: Ideal for odor-sensitive packaging such as coffee, tea, dairy, and frozen foods.

Technical Data: In third-party migration testing (40°C for 10 days), overall migration levels remained below detectable limits under standard testing protocols.

2. Strong Adhesion on Plastic Films

Water-based inks were traditionally limited to paper substrates. StarColor’s hybrid acrylic–polyurethane resin technology significantly improves wetting on low surface energy films.

• Adhesion Performance: Achieves ASTM D3359 5B rating on properly corona-treated PE, PP, and BOPP films.
• Post-Processing Resistance: Excellent flexibility during die-cutting, lamination, and hot stamping without cracking or delamination.

3. High-Speed Press Compatibility

Modern narrow-web presses frequently exceed 200 m/min. Drying efficiency is critical for stable output.

• Optimized Evaporation Curve: Controlled drying behavior reduces plate clogging while enabling rapid substrate drying.
• Energy Efficiency: Requires 10–15°C lower drying temperatures compared to traditional water-based inks, reducing operating costs.
• Low-Foam System: Maintains stability in high-speed circulation systems, minimizing downtime.

4. High-Impact Color Performance

• High Pigment Concentration: Nano-dispersion technology improves color strength by approximately 20%, allowing thinner ink films and faster drying.
• Enhanced Gloss: Smooth film formation delivers near-UV gloss appearance.
• Pantone Matching & Custom Shades: Ensures brand color consistency across batches.

5. Genuine Sustainability Commitment

• Ultra-Low VOC Content: VOC levels below 1%, improving workplace safety.
• Carbon Footprint Monitoring: Production processes are monitored to support customer ESG reporting.

Case Study: Food Packaging Converter Upgrade

Background: A leading frozen food packaging converter previously used solvent-based inks and faced regulatory pressure, odor complaints, and export restrictions.

Solution: Full transition to StarColor water-based flexo ink series.

Results:

• Successfully passed international retail compliance audits, securing export contracts valued at over $1,000,000 USD.
• Press speed increased from 200 m/min to 300 m/min.
• Drying energy consumption reduced by 15%.
• Customer complaint rate reduced by 90%, with excellent performance at -18°C frozen storage conditions.

“StarColor inks solved our compliance concerns and exceeded expectations in print performance. They are now our strategic solution for premium food packaging.”
