Bio-based barrier to replace aluminium
Purpose and goal
Today, a thin layer of aluminium is used as a gas barrier in many packaging products. From a sustainability perspective, a green alternative based on renewable materials is desirable. The purpose of the project is to apply a thin layer of bio-based material to paperboard, in order to, together with a biofilm, be able to replace energy-intensive aluminum foil as a gas barrier.
Expected results and effects
By creating a new application for Swedish forest raw materials and developing a biobased renewable barrier material suitable to replace energy-demanding aluminum foil, we can take an important step to move Sweden towards bio-based socioeconomics. In addition, through pilot scale trials, we want to identify and address those issues which challenge upscaling of the renewable coating into full scale industrial production.
Planned approach and implementation
The project will be carried out by Iggesund Paperboard/Holmen AB, RISE and Tallriksfabriken as project partners. In addition, subcontractors will be engaged. These companies and subcontractors cover the entire value chain from material provider, to machine supplier, coating expertise, renewable barrier material expertise and analyses (RISE), producer (Iggesund/Holmen) and converter (Tallriksfabriken).
