Tiivistelmä
The main objective of the present study was to analyze the best approach on how to coat paperboard trays at the pressing stage. The coating gives the paperboard enhanced barrier and mechanical properties.
The whole process chain of the barrier coating development was studied in the research. The methodology applied includes obtaining the optimum temperature at which good adhesion and bonding is formed between paperboard and skin film. Evaluation of mechanical properties after the coatings; such as cracking, curling and barrier properties was performed.
