PLA Food Packaging Application
Fenómeno do problema
PLA food packaging deforms due to insufficient heat resistance, or composting condition claims cause controversy
Análise das causas
PLA suits disposable tableware and food packaging; but heat resistance limits hot food applications; industrial composting conditions (above 58℃ humidity) are needed for rapid degradation, and degradation is slow in natural environments
Solução
①Cold food packaging fully leverages PLA advantages; ②Select heat-resistant modified grades for hot food; ③Degradation claims stated per industrial composting conditions; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
PLA food packaging is positioned in cold food disposables; degradation claims must state the industrial composting premise; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
