CASSPAK is the next generation of bio-based foams for sustainable packaging, made from 100% cellulose for the protection and cushioning of fragile goods. Using 0% detergents and non-hazardous processing, the major input for the production of CASSPAK foams is the brown (knot reject) residual streams of the paper and pulp industry. With advanced nanocellulose expertise and breakthrough cellulose foaming technology, CASSPAK foams are the future in sustainability of the packaging industry. These bio-based foams are light weight with good mechanical strength and are an excellent alternative that will replace fossil-based ones, like expanded polystyrene (EPS). As CASSPAK foams are made of 100% cellulose fibres, they can be thrown directly into the compost and do not create pollution or accelerate climate change. Alternatively, the foams can be recycled back into the process, becoming a truly circular product and further adding to the world’s conversion to a bio-based social economy.
The aim of the project will be to validate that the CASSPAK foam technology, in laboratory conditions, is a viable bio-based foam packaging solution. Ecological, economical and social sustainability of CASSPAK foams will be taken into consideration at all stages of the project.
Goals for the project are:
- Optimise the raw material addition and foaming processes without reducing functionality.
- Chemical composition of the raw materials and finished CASSPAK foams.
Participants
Cass Materials AB, Domsjö AB, Borregaard AS and HJ Freezing Solutions ApS.
Budget & time plan
The project’s total budget is 810 000 SEK and the project runs during six months – between July and December 2023.
