Product Highlights

The L50N packaging machine is engineered to excel across multiple dimensions of performance, reliability, and adaptability, providing a comprehensive solution for diverse packaging needs.

Versatile and Adaptable Performance

This machine demonstrates exceptional versatility, capable of handling a wide array of products including powders, liquids, granules, tablets, and viscous sauces through the use of interchangeable metering pumps. Its design allows for quick and straightforward adjustments, enabling a seamless transition between different product types and bag styles. This flexibility significantly reduces production downtime and enhances overall operational efficiency, allowing manufacturers to respond swiftly to varying market demands and production schedules.

High-Speed and Precision Operation

Engineered for efficiency, the equipment achieves impressive speeds of up to 100 cuts per minute while maintaining exceptional metering accuracy within a range of ±1–3%. This ensures consistent bag dimensions, superior sealing integrity, and precise cut quality batch after batch. The integration of stepper motor control guarantees smooth and controlled bag movement throughout the packaging cycle, while the specialized rotary cutters provide clean, accurate separations without film fraying or residue, contributing to a polished final product.

Durable and Hygienic Construction

Built to withstand the rigors of continuous industrial use, the machine features a construction centered on 304 stainless steel for all components that come into contact with the product. The frame is welded for maximum stability, and the exterior boasts a brushed finish for both aesthetics and durability. Transparent acrylic safety covers, equipped with door detection switches, provide optimal operator protection while allowing for visual monitoring of the process. This design not only safeguards personnel but also ensures full compliance with international food safety and hygiene standards. Furthermore, key sealing components are modular, extending the machine’s service life and greatly simplifying maintenance and part replacement procedures.
