EVENT REVIEW PETplanet Insider Vol. 26 No. 10/25 www.petpla.net 42 Advances in PET packaging promise lighter bottles and lower costs KHS featured various new developments related to PET at drinktec 2025: The company presented the premium LITE PET bottle with Husky, the InnoPET FreshSafe QuadBlock monobloc line and low-labour AutoReel label storage. InnoPET FreshSafe QuadBlock monobloc line The InnoPET FreshSafe QuadBlock monobloc production line is claimed to offer improved energy efficiency, a smaller production footprint, lower maintenance costs and improved recyclability and sustainability. The FreshSafe QuadBlock integrates several core manufacturing processes into a single, monobloc machine that combines stretch blow moulding, labelling, filling, and barrier coating and thus streamlines the production process and boosts overall efficiency, as well as reducing the risk of cross-contamination. The machine incorporates InnoPET Plasmax barrier technology, which applies a thin glass layer inside the PET bottles, protecting the contents from oxygen ingress and carbon dioxide loss. This barrier coating extends the shelf life of carbonated beverages, which is particularly helpful for products that require long-term storage. The coated bottles remain fully recyclable, so they can be reprocessed and reused, which is an increasingly important factor in today’s environmentally conscious market. No blower unit The system labels the bottles when they are dry, which eliminates the need for a blower unit and consequently cuts energy consumption. This design also reduces the number of conveyor drives by 60%, which helps to improve sustainability and availability. The streamlined container conveying segments and end-to-end neck handling further boost efficiency and space-saving capabilities, making it an attractive option for production environments with spatial constraints. The system’s modules operate in common mode, which enables simplified handling and less human labour. Although the FreshSafe QuadBlock is a single unit, its modular design and construction enables the modules to be serviced independently, which means that parallel maintenance can be undertaken without halting production. The FreshSafe QuadBlock delivers finished PET bottles that are coated, labelled, filled and capped, ready for packing and palletizing. The system’s ability to produce lightweight PET bottles with optimum stability allows for material savings and thus reducing the overall cost of production. The seamless integration with downstream packers and palletisers is designed to ensure a smooth, efficient, end-to-end production chain.
