Product Overview

The Keypack Intelligent (Kunbupack) Powder 3-Side Seal Bag VFFS Packaging Machine KL-300F is a vertical form-fill-seal system engineered specifically for automated powder packaging with three-side seal bag formation. This machine combines precision metering, reliable bag forming, and secure sealing in a single integrated platform designed for regulated production environments. Equipped with a PLC servo drive system and large-format touchscreen interface, the KL-300F maximizes control precision and operational reliability across diverse powder applications.

The full stainless steel 304 body ensures durability and compliance with food-grade and pharmaceutical hygiene standards, while the intuitive touchscreen interface enables operators to store packaging process parameters for multiple products. This allows instant product changeovers without manual reconfiguration, reducing downtime and improving production flexibility. Standard features include color mark detection for accurate bag positioning, ribbon date coding for traceability, and sponge air exhaust for optimal bag quality and product preservation.

This machine integrates seamlessly with metering systems and conveying equipment tailored to powder characteristics, automating the complete packaging workflow: metering, filling, three-side seal bag forming, gas flushing or evacuation, date printing, and counting. Safety protection features meet enterprise safety management requirements, ensuring operator protection during high-speed operation.
