Sun Chemical has expanded its nitrocellulose-alternative ink portfolio for flexible packaging, addressing supply issues, rising costs, and sustainability concerns linked to nitrocellulose (NC). The new inks are designed to be fully compatible with recycling processes, aligning with RecyClass and CEFLEX guidelines, and offer converters a smoother transition to NC-free systems while maintaining press stability and supply continuity.
Portfolio expansion details
The expanded portfolio includes NC-alternative inks, coatings, primers, and adhesives optimized as a complete system for both flexo and gravure printing. Key products include SunSpectro SolvaCycle for surface printing, SunStrato DuraCycle, SunStrato Duratort, and SunStrato Duralam for lamination printing, and SunUno SoliCycle, a multipurpose option for both surface and lamination applications.
Supply-chain and compliance benefits
Sun Chemical states that the modular system, based on polyurethane (PU) concentrates, enables a smooth transition from NC/PU inks to NC-free alternatives, reducing risks from supply chain volatility. The inks also help lower eco-modulated Extended Producer Responsibility (EPR) fees and support compliance with plastic tax requirements by ensuring quality recyclate availability.
What buyers should watch
Importers and converters should evaluate the total cost of goods benefits, including potential savings on regulatory costs and EPR fees. The inks' compatibility with recycling design guides and end-of-life requirements may also help meet evolving packaging sustainability regulations in Europe and other markets.
Industry context
Last summer, Toyo Ink Europe launched its Steraflex GIO flexographic printing ink for label substrates, emphasizing migration safety. More recently, Mondi added white inks for brown materials to its digital printing range for corrugated board, with water-based formulations approved for food safety by Swiss Quality Testing Services (SQTS).
