Powder Metering Vertical Form-Fill-Seal Machine

Keypack Intelligent Powder Metering Vertical Form-Fill-Seal Machine is a PLC-controlled VFFS Machine engineered for accurate, continuous packaging of free-flowing powdered materials. It delivers stable output from 5 to 100 bags/min across six model configurations, with integrated auger filler and intelligent temperature-controlled sealing. Ideal for food powder packaging, dairy powder packaging equipment, pharmaceutical powder packaging, and chemical powder packaging machine applications.

Product Overview

The Keypack Intelligent (Kunbupack) Powder Filling Machine is a fully automatic Vertical Form-Fill-Seal Machine that integrates screw metering (auger filler), bag forming, filling, sealing, date printing, gas flushing or exhaust, finished product conveying, and automatic counting into a single continuous workflow. Driven by a PLC servo control system and pneumatic control system, the machine operates through an extra-large touchscreen HMI that stores multiple product packaging parameter sets — enabling fast changeover without manual resetting when switching between powder types or bag formats.

Available in six models — KL-320, KL-420, KL-520, KL-620, KL-820, and KL-1250 — this Vertical Packaging Machine covers a wide range of bag sizes from (L) 60 mm up to (L) 800 mm and production speeds from 5 to 100 bags/min, making it scalable from mid-volume to high-volume powder packaging lines. Each model is configurable with compatible weighing systems, auger filler systems, and conveying systems based on the specific powder material and production requirements.

The machine supports pillow-type bags and hanging-hole bags, and uses either a single-belt or dual-belt film pulling system for fast, stable, low-friction film transportation. A built-in fault display system assists operators in rapid troubleshooting to minimize production downtime.

Key Features and Machine Characteristics

• PLC Servo Control + Pneumatic System + Touchscreen HMI: The core drive control architecture combines a PLC servo system, pneumatic control, and an extra-large touchscreen interface to deliver high control precision, operational reliability, and intelligent automation across the full packaging cycle.
• Intelligent Temperature Control for Sealing: An intelligent temperature controller maintains accurate sealing temperature throughout production, ensuring neat, flat, and consistent seals on every powder packaging bag — reducing seal defects and material waste.
• Multi-Parameter Touchscreen Storage: The touchscreen HMI stores packaging parameters for multiple product types. When switching between powders or bag formats, operators can recall saved settings instantly without reconfiguration, reducing changeover time on the powder packaging line.
• Integrated Full-Process Automation: When paired with compatible auger filler and conveying systems, the machine automatically completes powder metering, feeding, bag forming, filling, sealing, gas flushing or exhaust, date printing, finished product conveying, and counting in a single uninterrupted workflow.
• Single-Belt or Dual-Belt Film Pulling: Both single-belt and dual-belt film transportation options are available, providing fast, stable, low-friction, and low-wear film feeding — suitable for sustained high-speed VFFS machine operation.
• Fault Display and Diagnostics: A built-in fault display system identifies machine status in real time, helping operators locate and resolve issues quickly to minimize unplanned downtime on the powder filling line.
• Safety Guard Enclosure: Equipped with safety guards that meet industrial safety management requirements for automatic packaging equipment environments.
• Flexible Bag Format Support: Supports pillow-type bags and hanging-hole bags, with customization available based on specific packaging format requirements.

Application Areas

• Food Powder Packaging: Milk powder filling and sealing for dairy production lines; protein powder portioning for sports nutrition brands; spice powder and seasoning packaging for food manufacturers; flour and starch packaging for bakery and food processing; instant drink powder and coffee powder packaging for beverage producers; milk tea powder packaging for ready-to-drink mix lines.
• Pharmaceutical and Nutritional Powder Packaging: Medicinal powder filling for pharmaceutical packaging lines; nutritional supplement powder packaging for nutraceutical producers; fine powder materials requiring dust-controlled, precise auger filler metering.
• Chemical Powder Packaging: Detergent powder packaging for household and industrial cleaning product lines; chemical powder packaging machine applications for industrial powder materials requiring sealed, labeled, and counted output.
• Automatic Powder Packaging Lines: Turnkey integration as a Vertical Form Fill Seal Machine within end-to-end packaging lines requiring Powder Filling Machine, Auger Filler, Automatic Powder Filler, and Vertical Packaging Machine capabilities in a single footprint.
