LLDPE agricultural film application
Problem Phenomenon
LLDPE agricultural film is more puncture resistant and longer-lived than LDPE, but costs more
Cause Analysis
LLDPE's puncture resistance and ESCR are better than LDPE, giving agricultural film a longer service life; but raw material cost and processing difficulty are higher; select comprehensively by planting cycle and cost
Solution
①Choose LLDPE agricultural film for long-cycle planting; ②choose LDPE for short-cycle or cost-sensitive cases; ③configure UV stabilization system by service years; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The life advantage of LLDPE agricultural film needs to be balanced with cost; make economical selection by planting cycle; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
