Powder High-Speed Packaging Machine G420

The Keypack KL-G420 is a high-speed Vertical Form-Fill-Seal (VFFS) machine designed for continuous automated packaging of free-flowing and fine powder materials at industrial production rates. Driven by a 5-servo multi-axis system with PLC control, the KL-G420 operates at 100–150 bags/min across back-seal, gusseted, and hang-hole bag formats (L: 80–300 mm, W: 80–200 mm). It is suited to powder packaging applications in dairy, instant beverage, food seasoning, animal feed, and nutraceutical manufacturing, where consistent fill accuracy, stable seal quality, and sustained high-speed output are primary operational requirements.

Product Overview

The KL-G420 High-Speed Vertical Powder Packaging Machine is purpose-built for free-flowing and fine powder material packaging, integrating a 5-servo motor system, pneumatic control, and a touchscreen HMI as its core drive and control architecture. The dual film-pulling structure ensures consistent bag formation and stable film feeding at rated speed, while independent electrical and pneumatic control cabinets reduce operating noise, improve sealing integrity, and extend overall machine service life.

Equipped with a Japan Koganei vacuum pump, the KL-G420 achieves rapid and stable film pulling even during sustained high-speed operation. The touchscreen HMI supports storage of multiple product packaging parameter sets, enabling fast format changeover between different powder SKUs with minimal manual intervention. A built-in fault display system provides real-time diagnostics, helping operators identify and resolve issues promptly to minimize unplanned downtime.

The machine automatically completes the full packaging sequence — powder metering, filling, bag-making, gas flushing or nitrogen flushing, date printing, and counting — forming a complete, integrated automated powder packing process. Keypack Intelligent (KunbuPack) VFFS Powder Packaging Machine is designed to interface with upstream auger screw fillers, weighing systems, or volumetric metering units, and downstream conveying systems, supporting turnkey end-to-end powder packaging line configurations.

Key Features and Machine Characteristics

• 5-Servo Multi-Axis Drive System: Delivers high motion control precision across all packaging stages, reducing mechanical wear and supporting stable long-term operation at rated speed — particularly important for consistent powder dosing and seal quality.
• Intelligent Temperature Control: Smart temperature controller maintains accurate sealing temperatures, producing clean, flat, and consistent seals across all supported bag formats and powder film materials.
• Japan Koganei Vacuum Pump: Ensures stable, high-speed film feeding with low vibration — supporting sustained output without performance degradation during continuous powder packing runs.
• Touchscreen HMI with Multi-Recipe Storage: Operators can save and recall packaging parameters for different powder products, enabling fast changeover with minimal manual adjustment and reduced setup time between SKUs.
• Built-in Fault Diagnostics: Real-time fault display system identifies issues promptly, reducing troubleshooting time and supporting continuous, uninterrupted powder filling and sealing production.
• Independent Electrical and Pneumatic Control Cabinets: Separated enclosures reduce electromagnetic interference, lower operating noise, improve sealing performance, and extend machine service life — critical for powder environments where dust ingress is a concern.
• Safety Protection System: Designed in compliance with enterprise-level safety management requirements, supporting safe operation in regulated powder processing and food manufacturing environments.
• Flexible Bag Style Configuration: Supports back-seal bags, gusseted back-seal bags, hang-hole bags, and other formats — configurable per customer production and retail display requirements.
• Full-Process Automation: Integrates powder metering, filling, bag-making, gas flushing/nitrogen flushing, date printing, and counting into a single continuous automated workflow.

Application Areas

• Dairy & Nutritional Powder: High-speed back-seal pouch packaging for milk powder, infant formula base powder, and protein powder — suitable for free-flowing fine powders where consistent dosing accuracy and nitrogen flushing for freshness preservation are required.
• Instant Beverage & Coffee: Automated powder filling and sealing for instant coffee, solid beverage powder, and powdered drink mixes in composite film pouches, supporting high-volume production with stable seal quality.
• Food Seasoning & Condiment Powder: Powder packing for seasoning blends, spice powders, and flavoring agents in back-seal or hang-hole bag formats — suitable where powder flowability is within the auger or weighing system's operating range.
• Animal Feed & Agricultural Powder: Continuous automated packaging for animal feed powder, premix powder, and similar agricultural powder materials in large-format back-seal pouches — verify material bulk density and flowability before deployment.
• Nutraceutical & Health Supplement Powder: Powder filling and sealing for protein supplements, vitamin powder blends, and functional food powders where PLC-controlled precision filling, nitrogen flushing, and date printing are required — verify applicable regulatory requirements before deployment.
• Note on Material Suitability: This machine is optimized for free-flowing and fine powder materials. Highly hygroscopic, extremely fine ultramicro powders, or materials with significant clumping tendency may require additional upstream conditioning or specialized metering systems — confirm material compatibility at the project quotation stage.

Customization and Optional Modules

• Compatible with auger screw fillers, weighing systems, or volumetric cup fillers based on powder material properties and required dosing accuracy.
• Bag style configurable to pillow bags, hang-hole bags, gusseted back-seal bags, and other formats per customer requirements.
• Supports nitrogen flushing module for oxygen-sensitive powder products requiring modified atmosphere packaging (MAP).
• Supports integration into turnkey end-to-end powder packaging lines including upstream powder conveying, downstream labeling, checkweighing, and palletizing systems.
• Packaging film material options: PET/PE, OPP/CPP, OPP/PE, and other composite films — selection based on product barrier requirements and retail packaging standards.
