Short storage period of PLA pellets
Problem Phenomenon
The quality of PLA pellets decreases after storage for more than 6 months.
Cause Analysis
PLA slowly degrades at room temperature (hydrolysis and thermal degradation), and the storage period is limited.
Solution
First-in, first-out management; sealed moisture-proof storage; use near-expiry products after verification.
Key Takeaway
PLA shelf life management is a supply chain concern.
