PBAT thickness reduction
Problem Phenomenon
Insufficient strength after PBAT film thinning, breaking in use, contradiction between cost and performance.
Cause Analysis
PBAT strength is low and thickness demand is large; mechanical properties insufficient after thinning; stress in use conditions; safety margin; cost pressure.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Blend modification to improve strength before thinning; ②evaluate use conditions; ③safety margin design; ④multi-layer structure optimization.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PBAT thinning is a trade-off between cost and performance; modification is the technical support; evaluation ensures safety.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
