Composting Degradation Management of PLA Products
Problem Phenomenon
The product's degradation behavior does not match the claims.
Cause Analysis
PLA requires industrial composting conditions to fully degrade; it degrades slowly in the natural environment.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Clarify the degradation condition claims; ②Verify by standard testing; ③Manage customer expectations; ④Select suitable applications.; After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PLA degradation is conditional; claims and verification must match.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
