It delivers stable output across a wide bag-width range of 50–600 mm with multi-axis servo and PLC control, ensuring consistent seal quality and minimal film waste. Ideal for food, pharmaceutical, and chemical production lines requiring flexible, fully automated vertical form-fill-seal packaging.\u003c\/p\u003e\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Keypack Intelligent (kunbupack) Vertical Form-Fill-Seal Machine is a fully automatic back-seal vertical packaging machine designed to handle a broad spectrum of materials — from free-flowing granules and fine powders to viscous liquids and irregularly shaped solids. Compatible with pillow bags and gusset bags, this VFFS machine integrates metering, film forming, filling, sealing, date printing, gas flushing\/vacuum, and finished-product conveying into a single continuous process. The system supports film widths from 320 mm to 1,250 mm and bag sizes from 50×60 mm up to 600×800 mm, making it one of the most versatile vertical packaging machines available for mid-to-large format applications.\u003c\/p\u003e\n\u003cp\u003ePowered by a PLC servo system combined with a pneumatic control system and an oversized color touch-screen HMI, the machine achieves exceptional control accuracy and reliability. Recipe storage allows operators to switch between multiple product packaging parameters instantly — no re-programming required when changing SKUs. A built-in fault-display system identifies and guides rapid troubleshooting, minimizing unplanned downtime on your packaging line.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilm Width:\u003c\/strong\u003e 320 mm – 1,250 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBag Width:\u003c\/strong\u003e 50 mm – 600 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBag Length:\u003c\/strong\u003e 60 mm – 800 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Materials:\u003c\/strong\u003e Liquids, powders, granules, irregular solids\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e 220 V, 50\/60 Hz, 3.0 kW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressed Air Pressure:\u003c\/strong\u003e 6–8 kg\/cm²\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Consumption:\u003c\/strong\u003e 0.3 m³\/min\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBag Types:\u003c\/strong\u003e Pillow bag, gusset bag, hang-hole bag\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl System:\u003c\/strong\u003e PLC + multi-axis servo + pneumatic control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHMI:\u003c\/strong\u003e Large-format color touch screen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilm Drive:\u003c\/strong\u003e Single or dual belt film-pulling system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKey Features and Machine Characteristics\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Axis Servo \u0026amp; PLC Control:\u003c\/strong\u003e The drive core combines a PLC servo system, pneumatic control system, and oversized touch-screen HMI to maximize control precision, reliability, and intelligence — delivering consistent speed packaging performance shift after shift.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntelligent Temperature Controller:\u003c\/strong\u003e Precise sealing-temperature management ensures every seal is flat, clean, and aesthetically consistent — critical for food-grade and pharmaceutical packaging standards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull-Process Automation:\u003c\/strong\u003e Automatically completes metering, film feeding, bag forming, filling, date printing, gas flushing (or vacuum), finished-product conveying, and piece counting in one continuous cycle — zero manual intervention required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Recipe Touch-Screen Storage:\u003c\/strong\u003e Store packaging parameters for multiple products on the HMI.

It is compatible with both pillow bags (back-seal) and gusset bags. Switching between bag formats requires a tooling changeover; hang-hole punching is available as an optional add-on module for retail-ready packaging.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What types of materials can this machine handle, and do I need a different metering system for powders vs. granules?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes — the metering system is selected based on your material type. For free-flowing granules (candy, nuts, frozen food), a multi-head combination weigher is recommended. For fine powders (milk powder, starch, seasoning), an auger screw filler provides accurate volumetric dosing. For liquids and sauces, a liquid pump filler is used. The machine platform is the same; only the metering head changes, making it a flexible solution for multi-product facilities.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: How long does it take to change over to a different product or bag size?\u003c\/strong\u003e\u003cbr\u003e\nA: Changeover time depends on whether you are switching bag size, film width, or material type. For parameter-only changes (same bag format, different fill weight), the HMI recipe storage allows instant recall of saved settings — typically under 5 minutes. For physical format changes (different bag width or film roll), mechanical adjustments are required and typically take 20–40 minutes with a trained operator.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What are the installation requirements, and is on-site commissioning support available?\u003c\/strong\u003e\u003cbr\u003e\nA: The machine requires a 220 V \/ 50–60 Hz power supply (3.0 kW) and a compressed air supply at 6–8 kg\/cm² with a consumption rate of 0.3 m³\/min. A flat, level floor space sufficient for the machine footprint plus operator access clearance is needed. Factory acceptance testing (FAT) is completed before shipment.
