How long can I blow hot-filled PET bottles after PET bottle embryo injection? What are the preservation conditions of bottle embryos?

You look like a producer, not a polymer major. Injection molded bottle blank should be left standing for 24 ~ 48 hours to release and relieve the stress of bottle blank during injection, cooling and demoulding.

Bottle embryos should be kept in a constant temperature and humidity environment, and it is best to use them within one month. Otherwise the bottle embryo will be deformed and oxidized.

Lead to stretching, blow molding, and there is a danger of bursting.

Most importantly, the finished products after blowing, especially the bottles with gas, such as cola, will increase the air leakage rate, and at the same time, the experiment will be lost, which is more likely to lead to the risk of dripping.
