It delivers up to 150 BPM with multi-axis servo control and PLC-driven accuracy, ensuring consistent seal quality and minimal downtime across every production run. Ideal for snack food, grain, condiment, and pharmaceutical packaging lines that demand reliability at scale.\u003c\/p\u003e\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Keypack Intelligent (kunbupack) KP Series is a continuous vertical form-fill-seal machine built for modern high-speed packaging environments. Available in three models — \u003cstrong\u003eKP-420\u003c\/strong\u003e, \u003cstrong\u003eKP-520\u003c\/strong\u003e, and \u003cstrong\u003eKP-620\u003c\/strong\u003e — the series covers a wide range of bag widths from 80 mm to 300 mm, making it adaptable to diverse product formats and production scales.\u003c\/p\u003e\n\u003cp\u003eAt its core, the KP Series uses a \u003cstrong\u003eSiemens PLC control system\u003c\/strong\u003e paired with a full servo drive architecture (5 servo motors per model) and a large-format color touchscreen HMI. This combination delivers exceptional control precision, intelligent fault diagnostics, and the ability to store up to 100 product recipes — so changeovers are fast and repeatable without manual re-tuning.\u003c\/p\u003e\n\u003cp\u003eThe machine's center-mounted fill tube and naturally counter-balanced sealing jaw system enable smooth, vibration-free operation even at maximum throughput. A stainless steel 304 frame, vacuum pull belt, short film path, and no-tool changeover former all contribute to a machine that is as easy to maintain as it is powerful to operate. The integrated intelligent temperature controller ensures precise heat sealing for both lap seal and fin seal bag styles, producing clean, flat, and aesthetically consistent seals every time.\u003c\/p\u003e\n\u003cp\u003eThe KP Series supports full automation: from metering and feeding, through bag forming, filling, date printing, gas flushing (optional), and finished product conveying — all completed automatically with integrated counting.\u003c\/p\u003e\n\u003ch2\u003eModel Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eKP-420\u003c\/th\u003e\n\u003cth\u003eKP-520\u003c\/th\u003e\n\u003cth\u003eKP-620\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBag Width Range\u003c\/td\u003e\n\u003ctd\u003e80–200 mm\u003c\/td\u003e\n\u003ctd\u003e120–250 mm\u003c\/td\u003e\n\u003ctd\u003e150–300 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBag Length Range\u003c\/td\u003e\n\u003ctd\u003e80–300 mm\u003c\/td\u003e\n\u003ctd\u003e120–350 mm\u003c\/td\u003e\n\u003ctd\u003e150–400 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax.

Actual throughput depends on four variables: bag size (larger bags on the KP-520\/KP-620 run at 130\/110 BPM max), product flow characteristics (sticky, irregular, or heavy granules require slower fill cycles), filler discharge speed (the weigher or volumetric filler must keep pace with the VFFS), and film type (thicker or stiffer films need longer sealing dwell time). For most granule snack applications, 100–130 BPM is a realistic sustained production rate. We recommend sharing your product sample and target bag size so we can confirm the achievable speed for your specific application.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: How long does it take to change over from one bag size or product to another, and does it require tools or specialist technicians?\u003c\/strong\u003e\u003cbr\u003eThe KP Series is designed for fast, tool-free changeovers. The forming tube and former collar are quick-release components that swap without spanners or special tools. Sealing jaw width adjustments are servo-controlled via the HMI — no mechanical re-spacing required. Film width and bag length parameters are recalled instantly from the stored recipe library (up to 100 recipes), so the machine re-configures itself electronically. For a trained operator switching between two pre-stored recipes with the same film width, a full changeover typically takes 15–30 minutes. Switching film width (e.g., KP-420 from 80 mm to 200 mm bags) requires a former swap and film re-threading, which adds time but remains a single-operator task.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: At high speeds, how does the KP Series maintain consistent seal quality and prevent seal failures or film jams?\u003c\/strong\u003e\u003cbr\u003eSeal integrity at high speed is maintained through three interlocking systems. First, the servo jaw actuation ensures the sealing jaws close with precisely controlled force and timing on every cycle — unlike cam-driven jaws, servo jaws self-correct their position and are monitored by the auto reset detection system, which stops the machine and alerts the operator if jaw position drifts. Second, the intelligent temperature controller continuously monitors and adjusts sealing bar temperature in real time, compensating for heat loss at high cycle rates to keep the seal window consistent. Third, the vacuum pull belt maintains constant, calibrated film tension throughout the forming and sealing zone, preventing film slip or misregistration that causes wrinkled or weak seals. Together, these systems allow the KP Series to sustain high-speed operation without sacrificing the seal quality required for retail-ready packaging.\u003c\/p\u003e","brand":"Keypack Intelligent Technology Co., Ltd.","offers":[{"title":"Default Title","offer_id":43888923705422,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/5182\/4718\/files\/G420_2e0991aa-f2f9-4172-b813-9b5cf2f384d0.jpg?v=1781250528","url":"https:\/\/shkpack.com\/hi\/products\/high-speed-vffs-packaging-kpseries","provider":"Keypack Intelligent Technology Co., Ltd.","version":"1.0","type":"link"}
