Meeting China's growing demand for PET bottles


Atlas Copco's innovative ZD 40 bar compressor installed at Nestlé's Pure Life bottling facility in Shanghai

Whilst the adoption of PET bottling in China is comparatively recent when compared with other markets, this industry is now expanding at double digit figures of approximately 15% per year. The increase in demand for bottle grade PET parallels the growth in China's beverage industry which is increasing output at an average of 20% per year, the fastest growing category in the food market creating a very positive outlook for PET.

To meet this increasing beverage demand in China, Nestlé Pure Life mineral water used an additional Atlas Copco ZR 315 VSD FF and 40S30 booster, to ensure a constant supply of oil-free compressed air and maintain production capacity at all times including during unscheduled shutdowns. The new installation will not only increase efficiency but also create energy savings of up to 35% by continuously adapting the speed of the main drive motor to precisely match the air output to the air demand.

Compressed air is an essential resource in PET packaging and total absence of oil or pollutants is a crucial requirement. Atlas Copco's ZD 40 bar compressor is a combination of oil-free screw and piston technologies, endorsed by ISO 9001 quality assurance certification and is ISO 14001-certified for its environmental management. Throughout the entire compression, air is never in contact with oil. By uniting the two compression technologies, the ZD 40 bar compressor is highly effective on a large scale. 

The application of ZD 40 bar compressor is not limited to PET bottles. The technology can also be applied to other blow-molding markets where high pressure applications are required such as textile, automotive industries and robotics.
