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