Siegwerk has signed a contract to purchase Allinova, a specialty chemicals company with a portfolio including water-based dispersions, wax emulsions and adhesives.
Allinova is said to have “high technical competence”, especially in the formulation and production of water-based dispersions. Its product portfolio ranges from polymer dispersions to release agents and repellents.
Siegwerk says the acquisition represents a significant milestone in its global growth strategy, extending beyond converters into papermill and film manufacturing operations.
In April 2024, Siegwerk established a new global business unit dedicated to functional coatings for “sustainable” packaging innovations in line with a circular economy. The unit serves as a cross-divisional hub for circular solutions, adding specialized functional coating technologies to the company’s conventional coating offerings.
Earlier this year, the company introduced its nitrocellulose (NC) free ink series for surface printing on polyethylene (PE) and polypropylene (PP) packaging solutions, developed to meet packaging design guidelines such as those from RecyClass and CEFLEX. Apparently, the solutions utilize a set of proprietary, self-developed polyurethane binders as a replacement for nitrocellulose, said to have excellent printability and high heat and mechanical resistance.
More recently, Henkel Adhesive Technologies unveiled a new “fully recyclable” heat seal coating suitable for direct-contact packaging, enabling customers to adopt paper-based designs for products such as food, pharmaceuticals and home care. Henkel says the coating can be applied using flexographic and rotogravure technologies, expected to maximize strength at high machine speeds.
