KHS SUPREME PET bottle

The KHS SUPREME system is designed to take the protection of oxygen-sensitive beverages up to the next level. It combines the benefits of glass with the handleability of PET by applying KHS’s Plasmax barrier technology.

Suitable for quality-sensitive products such as green tea, the barrier technology provides a thin, transparent layer of silicon oxide that coats the inside wall of PET bottles like glass. Less than 100 nanometres thick, it is designed to protect the sensitive bottle content from oxidation, retaining its taste, colour and quality for lengthy periods of time.

This technology, originally developed for pharmaceutical glass containers, is based on many years of research. The first Plasmax systems were piloted in the food sector back in the early 2000s. Since then, KHS has further developed its Plasmax barrier and this year scaled it up to industrial production speeds of up to 60,000 bottles per hour.

The Plasmax technology is recyclable as the glass coating can be removed by caustic during the recycling process without affecting the quality of the material. The coating is also fully compatible with 100% rPET.

KHS will be presenting its system at interpack in Düsseldorf, Germany, from 7–13 May in Hall 13, Booth A31.
