Transparent glass barrier coating for Pet bottles
Ensure the longevity of sensitive beverages and liquid foods with glass barrier coating, combining superior product protection with the lightweight benefits of PET bottles for optimal preservation of quality and taste.

Applies Internal Glass Barrier Coatings
The InnoPET Plasmax series from KHS Group offers innovative PET bottle coating machines designed to extend the shelf life of sensitive liquid products. The Plasmax 12D, 20Q, and 20QS models specialize in applying a high-quality silicon oxide (SiOx) glass barrier coating to the interior of PET bottles, safeguarding contents like juices, wines, and detergents from gas infiltration while maintaining crystal-clear bottle appearance.
These machines are highly efficient, with the InnoPET Plasmax 12D processing up to 12,000 bottles per hour and the 20Q and 20QS models managing up to 40,000 and 46,000 bottles per hour, respectively. Their designs support continuous, high-speed production, integrating seamlessly with existing bottling lines through advanced PLC control systems.
The barrier coating process uses low media consumption technology, ensuring a sustainable, resource-conscious operation. Furthermore, the barrier is 100% recyclable, aligning with environmental standards and facilitating bottle-to-bottle recycling. Available coatings cater to various product pH levels without imposing additional temperature loads or internal pressure on filled containers.
Customizable options and engineering support are available to tailor the machines to specific production needs, ensuring optimal performance and integration within diverse industrial settings. With minimal maintenance requirements and optional CIP systems, the InnoPET Plasmax series promises reliable, long-term operation and ease of use.
