{"product_id":"vffs-machine-kl520","title":"Vertical Form-Fill-Seal Packaging Machine KL520","description":"\u003cp\u003eKeypack Intelligent KL-520 Vertical Form-Fill-Seal Machine is a high-performance VFFS Machine engineered for precise automatic metering and packaging of irregular lumps, granules, powders, and liquids. It delivers 30–80 bags\/min with PLC servo control, pneumatic systems, and a large touchscreen HMI, ensuring stable output and consistent seal quality across demanding production environments. Ideal for food packing machine applications, powder packing machine lines, and liquid packing machine configurations in food, nutraceutical, and industrial packaging.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Overview\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe Keypack Intelligent KL-520 is a versatile Vertical Packaging Machine Single Unit designed to handle a wide range of material types — from free-flowing granules and fine powders to irregular solids and semi-liquid products. As a fully integrated Automatic Metering Packaging Machine, the KL-520 combines metering, feeding, bag forming, filling, sealing, date printing, gas inflation or deflation, finished product conveying, and automatic counting into one continuous automated process.\u003c\/p\u003e\n\u003cp\u003eThe machine supports pillow bag and hang-hole bag formats, and can be paired with compatible metering systems (screw measurement or weighing measurement) and conveying systems based on the specific properties of the packaged material. With a bag-making size range of (L) 80–350 mm × (W) 80–250 mm and a packaging speed of 30–80 bags\/min, the KL-520 Vertical Form-Fill-Seal Machine is well-suited for both mid-scale and high-throughput packaging lines.\u003c\/p\u003e\n\u003cp\u003eKeypack Intelligent (Kunbupack) Vertical Packaging Machine systems are built around a PLC servo drive core, pneumatic control architecture, and an oversized touchscreen interface — delivering a control platform that prioritizes accuracy, reliability, and ease of operation. The touchscreen stores packaging parameters for multiple product types, enabling rapid changeover without manual re-configuration.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features and Machine Characteristics\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety-compliant design:\u003c\/strong\u003e Equipped with comprehensive safety protection devices that meet enterprise-level safety management requirements for automatic packing machine installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntelligent temperature control:\u003c\/strong\u003e Precision thermal controller maintains accurate sealing temperature throughout operation, producing clean, flat, and visually consistent seals — a critical requirement for food packaging machine and powder packing machine applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePLC servo + pneumatic + touchscreen control core:\u003c\/strong\u003e The integrated drive system maximizes control precision, operational reliability, and intelligent automation across the full packaging cycle — from filling to finished product discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully automated packaging process:\u003c\/strong\u003e When configured with appropriate metering units, the KL-520 Back-Seal Vertical Packaging Machine automatically completes metering, feeding, bag forming, filling, sealing, date printing, inflation or deflation, product conveying, and counting — with no manual intervention required between cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-product parameter storage:\u003c\/strong\u003e The touchscreen HMI stores packaging process parameters for multiple product types.
