PP Film Application
Problem Phenomenon
【Problem Phenomenon】Packaging films require transparency and heat resistance or high strength
Cause Analysis
BOPP biaxially oriented film is transparent and high-strength for packaging; CPP cast film has good heat sealability; PP film is a major packaging material; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
Select stretching-grade PP for BOPP; select copolymer material for CPP heat sealing; select the process according to transparency and heat-sealing needs; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PP film BOPP is transparent and high-strength, CPP has good heat sealing; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
