VFFS Powder Packaging Machine Medium Bags
Keypack Intelligent VFFS Powder Packaging Machine is a vertical form-fill-seal machine designed for high-precision powder sachet packing and filling operations. It delivers automated powder packaging at speeds of 5-80 bags per minute with PLC servo control system and intelligent temperature control for consistent, reliable bag forming and sealing. Ideal for milk powder, instant coffee, starch, seasoning powder, pharmaceutical powder, and chemical powder packaging applications requiring accurate metering and dust-free filling.
Product Overview
This vertical packaging machine combines advanced servo-driven technology with pneumatic control systems and large touchscreen interface to create a complete powder sachet packing solution. The Keypack Intelligent (Kunbupack) VFFS Machine integrates automatic metering, material feeding, bag forming, date printing, gas flushing (or air evacuation), and finished product conveying into a single automated packaging line with automatic counting functionality.
Available in five models (KL-420, KL-520, KL-620, KL-820, KL-1250) to accommodate different bag size requirements and production capacities, this powder packaging machine offers versatile solutions for small to large-scale powder filling operations. The intelligent temperature controller ensures precise heat sealing for beautiful, flat, and secure bag seals across various film materials. The touchscreen can store multiple product packaging parameters, allowing quick changeover between different products without resetting process parameters.
Equipped with comprehensive safety protection meeting enterprise safety management requirements, this vertical form-fill-seal machine features fault display systems that help operators quickly identify and resolve issues, minimizing downtime. The machine can produce pillow bags and bags with hanging holes according to customer requirements. Single-belt and double-belt film pulling systems ensure fast, stable film transport with minimal friction and material waste.
