With its new KHS InnoPET Plasmax 20QS development, the KHS Group company now offers a coating machine specially designed to produce bottles with volumes ranging from 100 to 350 ml.
Beverage producers can now process small format polyethylene terephthalate (PET) bottles particularly economically.
This glass interior coating, unique in the market, enables beverage producers to reduce material costs and achieve a longer shelf life especially for sensitive beverages.
“With our new development, we provide a solution that gives beverages bottled in small, economically attractive PET formats a longer shelf life,” says MD Joachim Konrad.
To date, especially small bottle formats of up to 350 ml had high volume-related gas permeability due to the adverse surface to volume ratio, which resulted in a relatively short best-before date versus glass bottles and cans.
Fast throughput
The sister model – the KHS InnoPET Plasmax 20Q – is intended for bottle formats of up to 1.5 L.
The new KHS InnoPET Plasmax 20QS is designed for formats with a maximum volume of 350 ml.
With the reduced-volume coating chambers and when compared with the Plasmax 20Q, this system can achieve a 20% higher output of up to 48,000 PET bottles per hour (output of 330 million bottles annually).
This adaptation makes operation with small bottle formats considerably more economical.
With Plasmax coating, a wafer-thin interior coating of pure glass, the bottles are in total lighter.
This saves up to 30% on materials and cuts PET processing costs.
Previously, material costs comprised an estimated 70% of bottle production.
