Contradiction between shelf life and degradation of PLA packaging materials
ظاهرة المشكلة
The packaging is required to have a shelf-life function but also needs to degrade under certain conditions.
تحليل الأسباب
The time coordination between the functional period and the degradation period (no degradation within the shelf life, premature degradation).
الحل
Control the degradation initiation timing through material design (barrier layer, additives).
الخلاصة الأساسية
The dual requirements of PLA function and degradation are a technical challenge.
