The project ran between June 2022 and June 2024.
In the project, materials were designed for press molding which in tests met the requirements to be recycled as paper. The product design (paper tube cap) was proven in consumer tests with prototypes meeting the market’s eligibility requirements for functionality. The developed fiber cap more than halved the environmental load measured as CO2 equivalents compared to conventional alternatives.
The fiber cap was included as one essential part of a paper tube concept that was presented at the Interpack fair in Dusseldorf May 2023 together StoraEnso and AISA. It attracted a lot of attention. For the commercialization of tube applications, brand owners highlight the need for an all-paper fiber system solution and request a paper fiber tube neck to offer a tube solution that is fully recyclable.
Participants
