Control of the biodegradation rate of PLA products
Problem Phenomenon
PLA products degrade too fast or too slowly in compost or soil.
Cause Analysis
The degradation rate of PLA is affected by the environmental temperature and humidity, microbial activity, and the characteristics of PLA itself (crystallinity, molecular weight, additives).
Solution
Adjust the degradation rate by blending and adding degradation accelerators or inhibitors; control the crystallinity of the product.
Key Takeaway
The regulation of the PLA degradation rate is the key to achieving a balance between functionality and environmental protection.
