Applicability of industrial softwood bark for CNF production and barrier films

Description

This study focused on mechanical fibrillation of the cellulose-rich bark residues into CNF and for barrier film testing. CNF films were prepared with varying polyphenolic (lignin and tannin) content and their properties were compared. According to the results fibrillation time of bark residue could be decreased significantly compared to a wood-based kraft pulp. Also, higher consistency in nanocellulose production was possible to achieve when softwood bark pulp is used instead of softwood kraft pulp. Bark-based CNF films produced functional barrier films with good oxygen, water vapor and grease barrier. The films had also clear antimicrobial properties.
