LLDPE heavy-duty packaging bag
Problem Phenomenon
LLDPE heavy-duty packaging bags rupture on drop, seal strength is insufficient, transport losses are high
Cause Analysis
LLDPE heavy-duty packaging film requires impact resistance and seal strength; mLLDPE or LLDPE/LDPE blend improves toughness; film thickness and sealing process are verified against drop standards
Solution
①Use mLLDPE or blended film for heavy-duty packaging; ②determine film thickness by drop test; ③sample-check seal strength batch by batch; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The reliability of LLDPE heavy-duty packaging bags is verified by drop testing; material upgrade plus seal sampling provides double insurance; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
