PET bottle drop test rupture
Problembeschreibung
PET bottle body ruptures in 1.2m or 1.5m drop tests, not meeting product standards.
Ursachenanalyse
Insufficient or unevenly distributed bottle wall thickness, stress concentration points in bottle body design, material IV too low or recycled material ratio too high.
Lösung
Optimize bottle shape to reduce stress concentration; increase wall thickness (bottom and shoulder); use high-IV raw material ≥0.80; optimize gate position.
Wichtigste Erkenntnis
PET bottle drop performance is the comprehensive result of bottle shape design, material selection, and process.
