Granule Back Seal VFFS Packaging Machine KL-300K
Keypack Intelligent Granule Back Seal VFFS Packaging Machine KL-300K is a high-precision vertical form-fill-seal machine designed for automated granular product packaging. It delivers 20-40 bags per minute with ≤±1% weighing accuracy, powered by PLC servo drive system and 304 stainless steel construction. Ideal for food, pharmaceutical, and chemical industries requiring reliable back seal or center seal bag packaging solutions.
Product Overview
The KL-300 Vertical Packaging Machine is a fully automatic back seal VFFS machine engineered for granular material metering and packaging. This servo-driven system integrates advanced PLC control with a large touchscreen interface, enabling precise bag formation, filling, sealing, and coding in one continuous operation. Built with full 304 stainless steel body, the machine ensures durability and compliance with food-grade and pharmaceutical standards. It supports multiple film types including Paper/PE, PET/AL, Foil/PE, Nylon/PE, and tea-leaf filtering paper, making it versatile across snack packaging, pet food packaging, tea packaging, coffee bean packaging, and seed packaging applications.
Equipped with Keypack Intelligent (Kunbupack) servo drive technology, the KL-300 offers synchronized process parameter backup, allowing operators to store and recall packaging parameters for multiple products without reconfiguration. The machine features color mark detection, standard ribbon date coding, and sponge air exhaust as standard functions. It can be paired with corresponding metering systems and conveying systems to automatically complete product weighing, bag making, gas flushing or air evacuation, date printing, and counting throughout the entire packaging process.
