Small VFFS Packaging Machine for 3/4 Side Seal, Back Seal & Shaped Bags
Keypack Intelligent KL-300 Vertical Form-Fill-Seal Machine (VFFS Machine) is engineered for precise, high-speed automatic packaging of granules, powders, and liquid/paste materials across food, pharmaceutical, and chemical industries. It delivers a packaging speed of 20–40 bags/min with weighing accuracy ≤±1%, powered by a PLC servo drive system and large touchscreen control. Ideal for sauce packaging, milk powder filling, candy and snack packing, pharmaceutical granule dosing, and chemical powder packaging.
Product Overview
The KL-300 is a fully automatic Vertical Packaging Machine designed to handle the complete packaging cycle — metering, bag forming, filling, sealing, gas flushing/evacuation, date printing, and counting — in a single integrated workflow. Built with a full 304 stainless steel frame, it meets GMP and food-grade hygiene standards, making it equally suited for food, pharmaceutical, and chemical production environments.
At its core, the KL-300 uses a PLC servo drive system paired with an oversized color touchscreen HMI, delivering exceptional control precision across all packaging parameters. Process parameters are automatically backed up and stored for multiple product profiles — switching between products requires no manual re-entry of settings, dramatically reducing changeover time and operator error.
The machine supports a wide range of bag styles including three-side seal, four-side seal, back seal, shaped/irregular pouches, and stick packs, with compatibility across multiple flexible packaging materials: Paper/PE, PET/AL, Foil/PE, Nylon/PE, tea-leaf filter paper, and more. Keypack Intelligent (kunbupack) KL-300 Vertical Packaging Machine is the reliable choice for manufacturers seeking consistent output, minimal downtime, and flexible format capability.

Key Features and Machine Characteristics
-
PLC Servo Drive Control: The servo motor drive system and large-format touchscreen HMI form the control core, maximizing overall machine precision and repeatability — critical for accurate weighing (≤±1%) across granule, powder, and liquid/paste materials.
-
Multi-Product Parameter Storage: Packaging process parameters are automatically synchronized and stored for multiple SKUs. When switching products, operators simply recall the saved profile — no manual re-configuration required, reducing downtime and human error.
-
Full 304 Stainless Steel Construction: The entire machine body is fabricated from 304 stainless steel, ensuring corrosion resistance, easy cleaning, and compliance with food-grade and pharmaceutical GMP hygiene requirements.
-
Integrated Safety Protection: Built-in safety guarding meets enterprise safety management standards, protecting operators during high-speed continuous operation.
-
Versatile Bag Format Compatibility: Supports three-side seal, four-side seal, back seal, shaped/irregular pouches, and stick packs — enabling one machine to serve multiple product lines and packaging formats without major mechanical changes.
-
Complete Packaging Automation: Automatically completes metering, bag forming, filling, gas flushing/evacuation (vacuum packing compatible), date printing, and counting in a single continuous process, minimizing manual intervention and labor costs.
-
Color Mark Detection + Ribbon Coding: Standard color mark sensor ensures precise film registration for printed packaging films; standard ribbon coder prints batch numbers, expiry dates, and production codes directly on each bag.
