PET how long can the bottle embryo be filled with PET hot filling bottle after long time? What are the conditions for preservation of the bottle embryo?
Bottle embryos should be kept in a constant temperature and humidity environment, preferably within a month. Otherwise, it will produce bottle embryo deformation and oxidation.Resulting in tensile, blow molding, there will be a risk of cracking.
Injection molded bottles should be placed for 24 hours to 48 hours to release and ease the bottle embryo in injection and cooling, as well as the release of film stress.
The most important thing is that after blowing the finished products, especially the gas bottle, such as cola, will increase the leak rate, while dropping the experiment, more likely to drop the risk of leakage.
The northern weather is relatively dry, the injection bottle embryos need to wet about four days, and then pull out for eight hours, while the South can directly blow bottles.
