Stack collapse of PET bottles during transportation
Problem Phenomenon
Empty PET bottles collapse during transportation and stacking, and the bottle bodies are crushed and deformed.
Cause Analysis
The bottle structure design is unreasonable and axial pressure-bearing strength is insufficient; bottle walls are too thin; storage temperature is on the high side and PET softens.
Solution
Optimize the bottle body by adding axial reinforcing ribs; increase wall thickness; control storage temperature ≤40°C; optimize the number of stacking layers.
Key Takeaway
PET bottle stacking performance is a comprehensive reflection of bottle design and storage management.
