Bottom Film Horizontal Flow Wrapping Machine KL-250

Keypack Intelligent Bottom Film Horizontal Flow Wrapping Machine KL-250 is a servo-driven automatic flow packing machine designed for high-speed horizontal packaging of regular-shaped products. It delivers 5-25 bags per minute with three-servo motor control and fiber-optic sensing technology for precise pillow bag formation. Ideal for food manufacturers packaging biscuits, bread, chocolate, mooncakes, and instant noodles, as well as daily necessities and industrial parts requiring reliable horizontal flow wrapping solutions.

Product Overview

The Keypack Intelligent (Kunbupack) Bottom Film Horizontal Flow Wrapping Machine KL-250 is an advanced servo flow wrapping machine engineered for automated packaging applications across food, industrial, and consumer goods sectors. This horizontal packaging machine features a three-servo motor system integrated with PLC control, enabling instant bag length adjustment without manual calibration or idle running. The one-step setup process reduces film waste and setup time compared to conventional flow wrappers.

Equipped with fiber-optic automatic sensing, this automatic flow packing machine detects product presence and initiates packaging cycles automatically, entering standby mode when no material is present to optimize efficiency and prevent empty bag production. The built-in self-diagnostic system displays fault codes clearly on the control panel, enabling rapid troubleshooting and minimizing production downtime.

High-sensitivity photoelectric color mark tracking with digital sealing position input ensures accurate seal placement for consistent package quality. Independent PID temperature control for each sealing zone adapts to various packaging materials including polyethylene, polypropylene, and laminated films. The simplified transmission system design delivers reliable operation with reduced maintenance requirements, while software-based control architecture allows convenient function adjustments and technology upgrades.

Available in two configurations—KL-250XDSF and KL-250XBSF—this bottom film flow wrapper accommodates different product heights and bag length requirements. The machine supports back seal bags, pillow bags, and perforated bags, with optional gas flushing capability based on customer requirements.

Key Features and Machine Characteristics

• Three-Servo Motor System with PLC Control: Bag length is set and cut instantly without adjustment or idle running, achieving one-step setup that saves time and reduces film consumption. The servo-driven system provides precise motion control for consistent bag formation across production runs.
• Fiber-Optic Automatic Sensing: Intelligent material detection automatically initiates packaging when products are present and enters standby mode when no material is detected, preventing empty bag production and optimizing operational efficiency for intermittent feeding applications.
• Self-Diagnostic Fault Detection: Built-in diagnostic system displays fault codes and error messages clearly on the PLC interface, enabling rapid troubleshooting and minimizing downtime. Operators can identify and resolve issues quickly without specialized technical knowledge.
• High-Sensitivity Photoelectric Color Mark Tracking: Digital input of sealing and cutting positions with precision color mark detection ensures accurate seal placement for professional package presentation. This feature is particularly valuable for pre-printed film applications requiring precise registration.
• Independent PID Temperature Control: Each sealing zone features dedicated PID temperature regulation, providing optimal heat distribution for diverse packaging materials including PE, PP, PET, and multi-layer laminated films. Temperature stability ensures consistent seal strength across varying production conditions.
• Positioning Stop Function: Machine stops at a preset position to prevent knife sticking and film waste, extending blade life and reducing material costs. This feature also facilitates safe maintenance and cleaning procedures.
• Simplified Transmission System: Streamlined mechanical design with fewer moving parts delivers reliable operation, easier maintenance, and reduced spare parts inventory requirements. The robust construction ensures long-term performance in demanding production environments.
• Software-Based Control Architecture: All control functions are software-implemented, allowing convenient function adjustments, parameter optimization, and seamless technology upgrades. This future-proof design maintains competitiveness as packaging requirements evolve.
• Multiple Bag Format Capability: Supports back seal bags, pillow bags, and perforated bags to accommodate different product protection and presentation requirements. Gas flushing option available for modified atmosphere packaging applications requiring extended shelf life.
