It delivers 20-40 bags per minute with ≤±1% weighing accuracy, powered by PLC servo drive system and 304 stainless steel dust-proof construction. Ideal for food, pharmaceutical, and chemical industries requiring contamination-free powder sachet filling and back seal bag packaging solutions.\u003c\/p\u003e\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe KL-300F Powder Packaging Machine is a fully automatic back seal VFFS machine engineered specifically for powdery material metering and packaging applications. This servo-driven vertical packaging machine integrates advanced PLC control with a large touchscreen interface, enabling precise bag formation, dust-free filling, sealing, and coding in one continuous operation. Built with full 304 stainless steel body and dust-proof back seal design, the machine ensures durability, hygiene compliance, and contamination prevention for food-grade and pharmaceutical powder packaging.\u003c\/p\u003e\n\u003cp\u003eThe system supports multiple film types including Paper\/PE, PET\/AL, Foil\/PE, Nylon\/PE, and tea-leaf filtering paper, making it versatile across milk powder packaging, seasoning powder packaging, traditional Chinese medicine powder packaging, and chemical powder packaging applications. Equipped with Keypack Intelligent (Kunbupack) precision screw metering technology, the KL-300F offers synchronized process parameter backup, allowing operators to store and recall packaging parameters for multiple powder products without reconfiguration.\u003c\/p\u003e\n\u003cp\u003eThe machine features color mark detection for accurate film registration, standard ribbon date coding for production traceability, and sponge air exhaust for improved bag appearance and powder settling. It can be paired with corresponding auger fillers, vacuum conveyors, and dust collection systems to automatically complete product weighing, bag making, gas flushing or air evacuation, date printing, and counting throughout the entire powder packaging process.\u003c\/p\u003e\n\u003ch2\u003eKey Features and Machine
