Description
Prime Brown is brown flat sack kraft paper. It is produced from pure, brown kraft pulp and consists entirely of virgin fibres. The long and strong fibres, from the Nordic slowly growing softwood forests, give the paper its inherent strength. Prime Brown is produced in compliance with BfR and FDA food packaging norms.
Basic usage
Prime Brown is a packaging paper with focus on strength and runnability. It is recommended for open mouth sacks in the food/feed and chemical industries, where demands are high.
