Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications
Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and
