Product Overview

The Keypack Intelligent (Kunbupack) Liquid 3-Side Seal Bag VFFS Packaging Machine KL-300Y is a vertical form-fill-seal system engineered specifically for automated liquid packaging with three-side seal bag formation and anti-drip technology. This automatic liquid packaging machine combines precision servo pump metering, drip-free filling, and secure sealing in a single integrated platform designed for viscous liquids, sauces, oils, and beverages in regulated production environments.

Equipped with a PLC servo drive system and large-format touchscreen interface, the KL-300Y vertical packaging machine maximizes control precision and operational reliability across diverse liquid applications. The dedicated liquid pump with servo control ensures accurate dosing without dripping or spillage, maintaining clean bag exteriors and preventing product waste. The full stainless steel 304 body ensures durability and compliance with food-grade and pharmaceutical hygiene standards.

The intuitive PLC touchscreen control enables operators to store packaging process parameters for multiple products, allowing instant product changeovers without manual reconfiguration. This reduces downtime and improves production flexibility when switching between different liquid products such as sauces, condiments, shampoo, engine oil, or health beverages. Standard features include color mark detection for accurate bag positioning, ribbon date coding for traceability, and sponge air exhaust for optimal bag quality.

This VFFS machine integrates seamlessly with liquid metering systems and conveying equipment tailored to liquid viscosity and flow characteristics, automating the complete packaging workflow: metering, drip-free 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 liquid packaging operations.
