Contradiction between shelf life and degradation of PLA packaging materials
문제 현상
The packaging is required to have a shelf-life function but also needs to degrade under certain conditions.
원인 분석
The time coordination between the functional period and the degradation period (no degradation within the shelf life, premature degradation).
해결 방법
Control the degradation initiation timing through material design (barrier layer, additives).
핵심 요약
The dual requirements of PLA function and degradation are a technical challenge.
