Description
Plant‑based biodegradable packaging uses renewable polymers such as PLA, starch blends, cellulose nanofibrils, and lignin to create moisture‑resistant, thermally tolerant films that reduce environmental impact.
Technical
These materials rely on hydrolytic chain scission (PLA, starch) and oxidative degradation (lignin) to break down. Their performance is governed by glass transition temperatures, melting points, and barrier properties that are sensitive to temperature and humidity. Chemical additives like glycerol, citric acid, and nano‑silica modify plasticizer migration, water uptake, and mechanical strength.
