Traditional beer is packed in glass bottles, which easily get exploded or broken, dangerous to consumers. Most of the complaints come from this hard solving headache. PET beer bottles have many advantages as low weight, high intensity, good tenacity, hard to be broken, convenient transportation, etc. PET beer bottle is simple to carry, and safe. Therefore, the world beer market began to transfer their gaze to PET bottles, in particular of Europe and Russian Federation.

Highly efficient lift spray nozzles are adopted, cleaning sufficiently and saving water as well. Long-tube filling valves are adopted, with CO2 fully exchanging with air inside PET bottles to decrease the rising of oxygen effectively. Level and pressure of filling cylinder are separately controlled by simulated level sensor and precision control valve.
