PC water bottle food container
Problem Phenomenon
【Problem Phenomenon】Food containers need transparency, heat resistance and safety
Cause Analysis
PC transparent and heat resistant used for space cups, baby bottles and water dispenser barrels; but bisphenol A concerns restrict infant products; select compliant grades；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
Food containers select compliant PC; infant products evaluate alternatives (Tritan/PPSU); heat resistance verification；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PC water bottles transparent and heat resistant, infant products pay attention to bisphenol A；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence；Include this case in the defect archive as a reference for troubleshooting similar problems in the future
