The Keypack Intelligent KL600 Vertical Form-Fill-Seal Machine is a servo-driven VFFS Machine engineered for precise back-seal bag forming across a wide range of flexible packaging films. It delivers a packaging speed of 4–15 bags/min with a maximum fill volume of 5,000 cc, supporting OPP, PE, PVC, OPP/CPP, OPP/PE, and PET/VMPET/PE materials. Ideal for food, powder, granule, and liquid packaging lines requiring stable, continuous automated operation.
Product Overview
The Keypack Intelligent (Kunbupack) KL600 Vertical Packaging Machine is designed for automatic measuring, bag forming, filling, sealing, date printing, gas flushing or evacuation, and finished product conveying — completing the full packaging process in a single continuous workflow. Driven by a PLC servo system paired with a pneumatic control system and a large touchscreen HMI, the KL600 achieves high control accuracy, operational reliability, and intelligent automation suitable for demanding production environments.
With a film roll width range of 220–560 mm and bag size range of L 150–480 mm × W 100–250 mm, this vertical form-fill-seal machine accommodates a broad variety of packaging formats. The belt-driven film feeding mechanism ensures fast, smooth film transport with low friction and minimal material waste, supporting long-term continuous production. The machine features both heat-seal and cold-seal dual modes, providing effective moisture and leak resistance for sensitive products.
The touchscreen control system stores packaging parameters for multiple product types, enabling rapid product changeover without reconfiguration. An integrated fault display system assists operators in identifying and resolving machine issues promptly, minimizing unplanned downtime.
