Description
Biodegradable food wrapping materials are engineered from renewable polymers such as PLA, starch, and cellulose nanofibers to provide mechanical strength and barrier properties while enabling controlled degradation under composting conditions.
Technical
These films rely on polymer chains that can be cleaved by hydrolysis and enzymatic action. The inclusion of plasticizers like glycerol and additives such as nano‑clay modulates chain mobility, affecting barrier performance and biodegradability. The overall performance is governed by extrusion temperature, film thickness, and environmental factors such as humidity and temperature.
