Fibre-based packaging has a potential to replace a significant share of difficult-to-recycle packaging materials. However, the scope applications for paper, board and molded pulp are still largely limited to products that do not require protection from water, water vapour, oxygen etc. Enabling barrier functionality in fibre-based packaging is key to unlock wider opportunity window for these materials and improve circularity and environmental performance of packaging systems globally.
Åbo Akademi University together with VTT Technical Research Centre of Finland is organizing an advanced course in barrier coating technology. In addition to doctorate level university students, the course is designed for industry professionals who want to increase their knowledge of fundamental aspects of barrier and barrier technology for paper, paperboard and molded pulp materials.
Organizers: Åbo Akademi University and VTT Technical Research Centre of Finland
Time: 28 February to 3 March, 2023
Course venue: Innopoli 1 Otaniemi, Espoo, Finland
