Keypack Intelligent Bottom Film Horizontal Flow Wrapping Machine WS-800 is a wide-format servo flow wrapping machine designed for high-efficiency packaging of regular-shaped products. It delivers 5-20 meters per minute packaging speed with 790mm maximum film width capacity, triple-servo motor control, and PLC automation with bilingual interface. Ideal for bakery products, confectionery items, instant noodles, daily necessities, hardware tools, and tray-packed produce requiring pillow bag or back seal bag packaging.
Product Overview
The WS-800 is an advanced automatic flow packing machine engineered for manufacturers requiring versatile horizontal packaging solutions across food processing, consumer goods, and industrial sectors. This bottom film flow wrapper combines precision servo technology with intelligent PLC control to accommodate oversized products up to 100mm in height, making it suitable for cookies, bread loaves, mooncakes, chocolate bars, instant noodle packs, hardware tool kits, and boxed or tray-packed items.
As a professional horizontal flow wrapping machine, the KL-800XDSF features a streamlined transmission system that enhances operational reliability while simplifying maintenance procedures. The machine supports multiple bag formats including back seal bags, pillow bags, and perforated bags, with optional gas flushing capability available upon request. Keypack Intelligent (Kunbupack) flow wrapping systems are built with software-driven control architecture, enabling seamless function adjustments, performance optimization, and future technology upgrades without hardware replacement.

Key Features and Machine Characteristics
1. Triple-Servo Motor Control with PLC Automation
Three independent servo motors synchronize film feeding, sealing, and cutting operations with digital precision. Bag length parameters are programmed directly into the PLC system and executed instantly without manual trial runs or mechanical adjustments. This servo flow wrapping machine architecture eliminates empty running cycles, reducing film waste by up to 70% during changeovers and saving valuable production time during format transitions.
2. Fiber-Optic Automatic Product Detection
Integrated fiber-optic sensing system continuously monitors product presence on the infeed conveyor. The automatic flow packing machine initiates wrapping cycles when products arrive and enters energy-saving standby mode when the line is empty, preventing empty bag production and conserving packaging film during upstream delays, batch transitions, or production pauses.
3. Self-Diagnostic Fault Display System
Real-time diagnostic module displays fault codes, error descriptions, and troubleshooting guidance directly on the bilingual HMI touchscreen. Operators can identify mechanical issues, sensor faults, or temperature deviations without specialized training, minimizing downtime and eliminating the need for external technical support during routine operations.
4. High-Sensitivity Photoelectric Color Mark Tracking
Precision photoelectric eye detects printed registration marks on pre-printed film with sub-millimeter accuracy. Seal and cut positions are digitally adjustable via the control panel, ensuring consistent brand alignment on printed packaging, reducing film waste from misregistration errors, and maintaining professional package presentation across high-speed production runs.
5. Independent PID Temperature Control
Dual-zone sealing system features independent PID temperature regulation for longitudinal and end seals. This adaptive temperature control accommodates diverse packaging films including polyethylene (PE), polypropylene (PP), laminated structures, and compostable substrates without manual recalibration, ensuring reliable seal integrity across material transitions and different film thicknesses.
6. Positioning Stop Function
Automatic jaw-return mechanism activates during machine stops, retracting the sealing bar to the open position. This prevents film adhesion to heated sealing surfaces, eliminates material waste during production pauses or changeovers, and protects packaging film from thermal damage during maintenance intervals or cleaning cycles.
7. Simplified Transmission System
Streamlined mechanical design with fewer moving parts and accessible service points increases operational reliability and reduces wear on critical components. Modular construction enables rapid cleaning procedures, simplified maintenance schedules, and faster replacement of consumable parts without specialized tools or extended downtime.
8. Software-Driven Control Architecture
All machine logic, motion control, and diagnostic functions are software-based, enabling remote parameter updates, feature enhancements, and performance optimization without hardware replacement. This future-proof design ensures long-term compatibility with evolving production requirements, Industry 4.0 integration capabilities, and emerging automation standards.
