Description
Biodegradable food packaging uses biopolymers such as PLA and starch blends that degrade via hydrolysis and microbial action under controlled conditions.
Technical
Polylactic acid undergoes hydrolytic cleavage of its ester bonds, producing lactic acid and eventually CO₂ and H₂O, while starch blends are enzymatically broken down into glucose and other sugars. The degradation rate is strongly temperature‑dependent, with optimal composting temperatures around 58 °C for PLA and 25–35 °C for starch composites. Moisture and oxygen availability further modulate the microbial consortia responsible for complete mineralization.
