Stretch blow molding with integrated coating for Pet bottles
Enhance product longevity and quality by integrating stretch blow molding with a unique interior coating, providing superior oxygen and CO2 protection for sensitive beverages such as juices and wines.

Coats and Forms PET Bottles
The InnoPET FreshSafe stretch blow molding coating unit block from KHS Group is a state-of-the-art solution that combines stretch blow molding with integrated coating technology, ideal for those in the beverage, food, and non-food sectors. It features a sophisticated process where PET bottle interiors are lined with a thin layer of SiOx glass coating. This enhances product freshness and significantly extends shelf life, making it an optimal choice for sensitive products like juices and wines.
With a production capability of up to 40,000 bottles per hour, it is designed for high-speed continuous operations, serving bottlers of beer, soft drinks, and more. The system is PLC-controlled for seamless integration into existing production lines and supports 100% bottle-to-bottle recycling, aligning with sustainability goals. Its energy-efficient approach minimizes operating costs by optimizing motor control and reducing rejection rates. Additionally, the InnoPET FreshSafe block offers gentle bottle handling via active mandrels and Touch-grip grippers, along with an efficient cleaning and maintenance process, ensuring minimal downtime. Customizable features include quick-change systems for various bottle neck diameters, enhancing flexibility and adaptability in production.
