Poor transparency of PLA blow bottles
Problem Phenomenon
After PLA '2079851475616104457, the bottle body is foggy and the transparency is not enough.
Cause Analysis
During the stretching process, PLA crystallizes and the haze increases; the preform heating temperature is high.
Solution
Control the preform heating temperature in the amorphous region; stretch quickly.
Key Takeaway
The transparency of PLA bottles is restricted by crystallization.
