Poor transparency of PLA blow bottles
Fenómeno del problema
After PLA '2079851475616104457, the bottle body is foggy and the transparency is not enough.
Análisis de la causa
During the stretching process, PLA crystallizes and the haze increases; the preform heating temperature is high.
Solución
Control the preform heating temperature in the amorphous region; stretch quickly.
Conclusión clave
The transparency of PLA bottles is restricted by crystallization.
