LLDPE Creep Deformation
Problem Phenomenon
LLDPE container deforms after stacking
Cause Analysis
Limited rigidity and creep accumulation; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
Stacking limitation; structural reinforcement; grade selection; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; Change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
Stacking deformation relies on structure and grade; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a troubleshooting reference for subsequent similar problems
