Abstract

Cellulose nanofibrils were produced from various biobased raw materials by grinding and high pressure homogenization. Films were produced by Erichsen lab-scale coater from banana, sugar beet, hemp, softwood and hardwood pulps and plasticized with 30 wt% of sorbitol. Water vapor transmission, grease penetration, oxygen transmission and mechanical properties including tensile strength and strain were measured and compared against each other. All films had high water vapor transmission rates varying between 20-24 g*mm/m2/day. Due to high number of polar hydrogen bonds in CNF, the films were impermeable to grease. All films had excellent oxygen barrier properties (
