Continuous packaging solution for free-flowing food products
Streamline your production with a high-speed packaging machine designed for precision and flexibility, ideal for sealing various bag types quickly without compromising on quality. Perfect for operations needing consistent output and adaptability to different product sizes.

The FLEX L packaging machine from KRONEN, in partnership with GKS Packaging B.V., offers seamless integration into industrial production lines for food manufacturers. It specializes in packaging a wide range of products, including vegetables, fruits, meat, and vegan items, using a vertical form-fill-seal process that ensures high-speed, continuous operation. With an adaptable design, the FLEX L accommodates various bag sizes from 75 mm to 350 mm in width and unlimited lengths, perfect for tailoring to specific product needs such as pre-packaged lettuce, fruit snack packs, and pet food pouches.
Capable of processing up to 50 bags per minute—or 70 with the servo-driven FLEX L Servo version—this machine supports high-capacity throughput, ideal for large-scale operations. It features advanced automation with Allen Bradley PLC systems, allowing flexible integration with existing line components, including weighing and labeling systems. Energy-efficient, the machine consumes minimal power and air, with a modular construction facilitating easy maintenance and rapid component replacement or upgrades.
Robust and precise, the FLEX L uses servo-driven film transport to ensure exact bag lengths and integrates seamlessly into production lines. Its hygienic design allows quick cleaning, while accessories like gas flushing and printing systems enhance its versatility. Suitable for processing all conventional film types, the machine is a reliable solution for ensuring product integrity and extending shelf-life in the food packaging industry.
