Pharmaceutical packaging: first compostable stick pack made of biobased raw materials

During the K’2022 Novamont (Novara, Italy) launched the first stick pack for a powdered multivitamin and multimineral supplement made of a paper laminate and Mater-Bi bioplastic film which is compostable and recyclable together with household food waste.

A highly innovative application, which arises from the will of DSM Nutritional products to offer a highly sustainable product without compromising the quality and stability of the product.

This packaging solution is the result of Novamont's collaboration with Ticinoplast (Pogliano Milanese), SAES Coated Films (Roncello), and Gualapack (Castellazzo Bormida), an entirely Italian industrial chain that has been engaged in intensive joint research and development for years. This association is based on the companies’ respective expertise in biodegradable materials, functional materials, and the transformation of these materials for the packaging sector, focusing in particular on regenerating resources and decarbonising production processes.

Unlike conventional packaging – employing PET, aluminium and PE – the new packaging is made of paper and film in Mater-Bi – the Novamont bioplastic produced from raw materials of agricultural origin. This means it is compostable in accordance with standard EN 13432, with a biobased raw material content of over 65 %.

The water-based biodegradable coating technology Coathink® from SAES Coated Films provides a high water vapour and oxygen barrier, necessary for optimum preservation of the powdered product and its micronutrient content throughout its shelf life. The pack is compatible with traditional automatic packaging lines thanks to its excellent sealability properties. The innovative pack not only guarantees shelf life and productivity similar to traditional laminates, but also solves the difficulties of recycling small packaging made from non-separable laminated materials.
