Stahl

Printing & packaging solutions

Manufacturers look for a competitive edge to entice consumers to buy their product. The shelf appeal of printed packaging can be a key differentiator. In the mere seconds of decision-making, a pleasing appearance can convince shoppers to pick up one product over the other options. Yet proper packaging can also increase product durability and convenience. Stahl's packaging coatings business unit offers a variety of printing and packaging solutions that enhance products and production alike.

Outstanding looks and qualities that enhance product experience

For producers that look for technical performance or aesthetic enhancing of product packaging, Stahl's packaging coatings business unit offers best-in-class polymer solutions for the printing and packaging industry. Our range of polyurethanes and acrylics for flexible packaging are used as binders for inks and printed onto films. Our polymer resins allow even for complex, multilayer food packaging structures that can withstand exposure to conditions like cooking and freezing. At the same time, these resins are designed to be safe, friendly in use and of high quality with many aesthetic options. These properties help ensure an optimal consumer experience with packaging that enhances the product experience.

Performance in production without compromise

Our resins for printing and packaging systems go beyond meeting the stringent demands for the (food) packaging segment with exceptional properties that improve the production process. These technologies enable formulators to develop inks for continuous high-speed printing, free of issues like webbing, sticking or wear and tear of equipment. Specially engineered to allow alcohol solubility minimizes the damage to flexo printing plates. Gravure printing is also possible by using the appropriate solvent blends. This ensures consistent high-performance printing, with long pot life and excellent chemical resistance.

Food contact approved binders and crosslinkers for printing & packaging

Part of our binders and crosslinkers portfolio for packaging is even compliant with the Swiss Ordinance (SR 817.023.21) for food packaging. They are suitable for varying sorts of packaging and coatings, such as packaging films (BOPP, PETR, PE-film, a.o), aluminum packaging, lamination foils, paper and plastic labels, paper and corrugated board, ink receptive coatings (such as gravure, flexo, flexo-UV, digital and inkjet printing), primers, overprint varnishes, mar-resistant matt coatings and soft-touch coatings.

Your partner in printing & packaging technology

We often work with our partners to create tailor-made solutions for custom requirements that meet exactly our customer’s demands. We use sophisticated processes to produce resins free of metallic catalysts. Our resins are tin-free, and thus suitable for the most demanding regulations in the packaging industry. At Stahl's packaging coatings business unit, we fully understand the importance of packaging solutions that ensure high-speed printing of materials that never deviate in looks. Long pot life and excellent chemical resistance ensures your packaging is consistent in its looks and performance. For consumers, that makes your product a recognizable, reliable and easy choice. Our team is ready to assist you in finding the right formulations and resins for your product.
