Description
Compostable packaging such as PLA, paper, and starch blends can be used in cooking up to moderate temperatures while maintaining sustainability.
Technical
PLA degrades thermally by chain scission producing lactic acid, paper wraps absorb moisture leading to hydrolysis of cellulose, and starch blends undergo gelatinization and enzymatic hydrolysis releasing glucose. These processes alter barrier properties and structural integrity, limiting their use to specific temperature and time windows.
