If PET information contains moisture, even if it is low, if it is low, if it reaches an impact on the article, it will still cause a series of problems. The material comes from the network. When storage, the PET bottle blank will absorb the humidity to the environment, and the full value can be as high as 0.s.

Generally, the water content of PET material particles is generally maintained between 0.3 (1000 ~ 3000 ppm) content, and it is necessary to reach the product function, it is necessary to drop the water content of PET information to 0.

The moisture in the bottle blank will also be similar to the plasticizer, enhance the stretching function of the bottle blank, and reduce the response effect, heating the process in the process Or will absorb more heat, make the blow molding of the bottle blank, and compared to a small diameter bottle blank,China plastic lotion pump head Factory the large diameter bottle blank is more affected by moisture.

And compared with the bottle embryo in time or fully automatic molding blower, the bottleblasts stored in a period of time may also have gravity orientation, so if you use semi-automatic two-step method to blow bottle, the bottle storage time is still Try not to have been too long.

According to the characteristics of PET, the solid PET is easy to absorbs the humidity in the air. Blowing equipment for blowing PET bottles generally Divided into two-step blowing machine and one-step blow molding machine, can also be divided into semi-automatic blow molders and automatic blow molders.

If you have any questions, please contact me to delete.Analysis of the quality of PET bottle embryo blow products PET bottle embryo is very common in life, more than a drink bottle. These two kinds of blowing machines currently have a good share in the market, if these two You can choose, so much better
