LLDPE toy application
Problem Phenomenon
LLDPE toys are more bite-resistant than LDPE, but cost more, with excellent low-temperature performance
Cause Analysis
LLDPE has excellent toughness, puncture resistance and low-temperature performance, suitable for bite-resistant toys; elongation at break of 400-700% provides excellent durability; cost is higher than LDPE
Solution
①Choose LLDPE for durable toys; ②choose LDPE for cost-sensitive cases; ③prefer LLDPE for low-temperature environment toys; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The durability advantage of LLDPE toys is clear; make graded selection by usage intensity and cost; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
