Powder Pneumatic Packaging Machine KL-300F

Keypack Intelligent Powder Pneumatic Packaging Machine KL-300F — Precision Powder Filling, Built for Scale

Keypack Intelligent KL-300F is a vertical form-fill-seal (VFFS) powder pneumatic packaging machine engineered for accurate, high-speed dosing of fine and free-flowing powders. It delivers ≤±1% weighing accuracy at 20–40 bags/min with a full stainless steel 304 body and PLC servo-driven control, meeting the strictest food, pharmaceutical, and chemical production standards. Ideal for spice powder filling, milk powder packaging, pharmaceutical powder dosing, and industrial chemical packaging lines.

Product Overview

The KL-300F is a cost-effective, stable, and durable vertical packaging machine  designed to automate the complete powder packaging process — from metering and bag forming to filling, sealing, date printing, and counting — in a single compact unit. Built on a full SUS304 stainless steel frame, the machine is dust-proof and easy to clean, making it compliant with GMP and food-grade production environments.

At its core, the KL-300F uses a PLC servo drive system paired with an oversized color touchscreen HMI, giving operators precise control over every packaging parameter. Process recipes for multiple products can be stored directly on the touchscreen and recalled instantly — eliminating re-setup time when switching between SKUs. The machine supports a wide range of bag styles and packaging films, making it a flexible, all-in-one powder filling machine for small-to-mid-scale production.

Keypack Intelligent (kunbupack) KL-300F can be paired with a matched metering screw feeder (dosing screw) and pneumatic conveying system to form a fully automated powder packaging line, completing metering, bag forming, gas flushing or evacuation, date coding, and counting without manual intervention.

Machine Specifications

Key Features and Machine Characteristics

• PLC Servo Drive System with Large Touchscreen HMI — The servo-driven control core maximizes overall machine precision and repeatability. The oversized touchscreen provides intuitive operation and real-time monitoring, reducing operator training time.
• Multi-Product Recipe Storage — Packaging parameters for multiple products are stored on the touchscreen and can be recalled instantly when switching products, eliminating re-calibration downtime and improving line efficiency.
• Full SUS304 Stainless Steel Body — Dust-Proof & Durable — The all-stainless construction is corrosion-resistant, dust-proof, and easy to sanitize, meeting food-grade and pharmaceutical GMP requirements. Stable and durable for long-term continuous operation.
• Metering Screw Feeder (Dosing Screw) Integration — Compatible with matched dosing screw / metering screw feeder systems for volumetric or gravimetric powder filling, ensuring consistent fill weights across high-speed runs.
• Safety Guards & Compliance — Equipped with safety protection covers that meet enterprise safety management standards, reducing operator risk on the production floor.
• Economical & Cost-Effective — The KL-300F delivers industrial-grade VFFS performance at an accessible price point, making it an ideal entry-level or secondary-line vertical packaging machine for growing operations.
• Automated Full-Process Packaging — Automatically completes metering, bag forming, filling, gas flushing/evacuation, date printing, and counting in one continuous cycle, minimizing labor and maximizing throughput.
• Color Mark Detection + Ribbon Coding — Standard color mark sensor ensures precise film registration; standard ribbon coder prints production dates, batch numbers, and expiry dates directly on each bag.

Application Areas

The KL-300F powder filling machine is optimized for fine, dry, free-flowing powders across food, pharmaceutical, and chemical industries. Specific applications include:

Food & Beverage:

• Milk powder: automatic volumetric filling into back-seal sachets for retail and foodservice
• Milk tea powder / instant beverage powder: high-speed sachet packaging for single-serve formats
• Spice powder filling: chili powder, cumin, turmeric, and blended seasoning powders into 3-side or 4-side seal bags
• Starch: corn starch, tapioca starch, and modified starch dosing into pillow bags
• Coffee powder: fine-grind coffee filling into foil/PE or PET/AL laminate sachets
• Condiment powder: salt, sugar, MSG, and seasoning blends into back-seal or 3-side seal packets

Pharmaceutical & Nutraceutical:

• Pharmaceutical powder: API and excipient powder dosing into unit-dose sachets under GMP conditions
• Herbal medicine powder: traditional Chinese medicine (TCM) granule and powder filling into filter paper or foil sachets
• Nutritional supplement powder: protein powder, probiotic powder, and vitamin powder sachet packaging

Chemical & Industrial:

• Chemical powder packaging: detergent powder, pigment powder, and fine chemical filling into sealed laminate bags
• Agricultural powder: pesticide powder and fertilizer micro-dosing into sealed sachets for retail distribution

Note: The KL-300F is designed for dry, free-flowing powders with low moisture content. It is not recommended for highly hygroscopic, sticky, or coarse granular materials without additional customization. Please consult Keypack Intelligent for material suitability assessment.
