PET Bottle Insufficient Top Load Strength
Fenómeno del problema
Bottles deform after stacking, collapsed bottles.
Análisis de la causa
Unreasonable wall thickness distribution (locally too thin), insufficient stretch orientation, excessive lightweight design; insufficient blowing pressure leads to insufficient orientation.
Solución
①Optimize wall thickness distribution (lamp zone adjustment); ②ensure high-pressure blowing orientation; ③top load test monitoring; ④verify top load while lightweighting.
Conclusión clave
Lightweighting forces top load management.
