KHS InnoPET Plasmax 20QS coating machine for small PET bottles

KHS Plasmax has released the InnoPET Plasmax 20QS coating machine for small PET bottles.

The machine is designed to produce bottles with volumes ranging from 100 to 350 mL, with a glass interior coating that enables beverage producers to reduce material costs and achieve a longer shelf life for sensitive beverages.

The reduced-volume coating chambers enable the machine to achieve an output of up to 48,000 PET bottles/h, equivalent to 330 million bottles annually.

The Plasmax coating, a wafer-thin interior coating of pure glass, results in a lighter-weight bottle, which saves up to 30% on materials and cuts PET processing costs, according to the company.

The glass coating enables the production of preservative-free beverages, and KHS Plasmax has developed a FreshSafe-PET logo to communicate this feature to consumers.

The machine is capable of running both the standard Plasmax process for products containing water, acid, fat and alcohol, in addition to the Plasmax process for applications with a high pH and carbonated beverages. The interior glass coating primarily protects sensitive beverages such as juice, wine, beer and carbonated beverages from loss of quality and preserves the flavour and the freshness of the product. The glass layer is virtually unbreakably bonded with the PET, and the bottles can be completely recycled.
