Water-soluble nanocrystalline cellulose films with highly transparent and oxygen barrier properties

Nanoscale. 2016 Jan 14;8(2):973-8. doi: 10.1039/c5nr07647a.

Abstract

By mixing a guar gum (GG) solution with a nanocrystalline cellulose (NCC) dispersion using a novel circular casting technology, we manufactured biodegradable films as packaging materials with improved optical and mechanical properties. These films could act as barriers for oxygen and could completely dissolve in water within 5 h. We also compared the effect of nanocomposite films and commercial food packaging materials on the preservation of food.
