It delivers 35–80 bags per minute across a flexible bag size range of L60–300mm × W60–200mm, with consistent fill-weight accuracy for every cycle. Ideal for food processing, chemical manufacturing, agricultural product packaging, and pharmaceutical granule bagging lines.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe KL-422 is a fully automatic double-line weighing and packaging machine purpose-built for granular materials. By running two independent packaging lines in parallel, the KL-422 effectively doubles production output compared to single-line machines — without requiring double the floor space or labor. The machine integrates a high-precision multi-head weighing system with a servo-driven film feeding mechanism and a PLC touch-screen control panel, enabling operators to set, monitor, and fine-tune every packaging parameter from a single interface.\u003c\/p\u003e\n\u003cp\u003eConstructed with food-grade stainless steel on all product-contact surfaces, the KL-422 meets strict hygiene standards for food and pharmaceutical applications. Its modular design supports rapid changeover between bag sizes and product types, minimizing downtime during production shifts. Whether you are packaging free-flowing granules, pellets, seeds, or coarse powders, the KL-422 delivers reliable, repeatable results at industrial scale.\u003c\/p\u003e\n\u003cp\u003eKeypack Intelligent (kunbupack) KL-422 is backed by a full-service support program including factory acceptance testing, on-site installation and commissioning, operator training, and a comprehensive spare-parts supply chain — ensuring your line stays running from day one.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eKL-422\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConfiguration\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDouble Line (Dual Channel)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePackaging Speed\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e35–80 bags\/min (per line;

In standard configuration, both lines are set to the same bag size and product parameters for synchronized high-speed output. However, the machine can be configured to run different bag lengths on each line simultaneously — contact Keypack Intelligent to confirm the specific dual-recipe configuration for your application.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eQ2: Can the KL-422 handle products with irregular granule sizes or mixed granule blends?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. The KL-422's multi-head combination weigher is designed to handle a range of granule sizes and mixed blends, provided the material is free-flowing and dry. For products with significant size variation (e.g., mixed nuts or blended seeds), the weigher head configuration and vibration settings can be tuned during commissioning to maintain target fill-weight accuracy within ±1%.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eQ3: How long does it take to change over the KL-422 from one bag size to another?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eBag-size changeover on the KL-422 is designed for minimal downtime. Adjusting bag width requires repositioning the forming tube and sealing jaws, while bag length is set digitally via the HMI. A trained operator can typically complete a full changeover in 15–30 minutes. Keypack Intelligent provides a changeover guide and operator training as part of the standard commissioning package.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eQ4: What after-sales support and warranty does the KL-422 come with?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe KL-422 includes factory acceptance testing (FAT) before shipment, on-site installation and commissioning support, and operator training. The machine comes with a standard 12-month warranty covering manufacturing defects on mechanical and electrical components. Keypack Intelligent maintains a spare-parts inventory for the KL-422 and offers remote technical support via video call for rapid fault diagnosis. Extended warranty and preventive maintenance contracts are available on request.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Keypack Intelligent Technology Co., Ltd.","offers":[{"title":"Default Title","offer_id":43931219492942,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/5182\/4718\/files\/KL422_3bf73bb1-0456-4031-94bf-a044d49087cb.png?v=1783304751","url":"https:\/\/shkpack.com\/id\/products\/vffs-granule-double-line-packaging-machine-kl422","provider":"Keypack Intelligent Technology Co., Ltd.","version":"1.0","type":"link"}
