Bottom Film Horizontal Flow Wrapping Machine WS-450

Keypack Intelligent Horizontal Flow Wrapping Machine designed for high-speed automatic packaging of regular-shaped products across food, bakery, and industrial sectors. It delivers 5-20 meters per minute packaging speed with three-servo motor control, PLC automation, and photoelectric color mark tracking for precise sealing. Ideal for biscuit packing, bread wrapping, chocolate packaging, mooncake sealing, and instant noodle bundling applications.

Product Overview

The Servo Flow Wrapping Machine represents advanced horizontal packaging technology engineered for consistent, reliable performance in medium to high-volume production environments. This Bottom Film Flow Wrapper integrates three independent servo motors with programmable logic control, enabling precise bag length setting without manual adjustment or trial runs. The system executes bag length parameters immediately upon input, eliminating empty cycles and reducing film waste during format changeovers.

Built by Keypack Intelligent (Kunbupack), this Automatic Flow Packing Machine features fiber optic automatic sensing technology that detects product presence and initiates packaging cycles automatically. When no product is detected, the system enters standby mode, conserving energy and extending component life. The intelligent control platform provides real-time fault diagnostics with clear visual indicators, allowing operators to quickly identify and resolve issues without extended downtime.

This Horizontal Packaging Machine supports multiple bag formats including back-seal bags, pillow bags, and punched bags with optional gas flushing capability based on customer requirements. The simplified transmission system enhances operational reliability while reducing maintenance complexity, making it suitable for continuous production in food processing, bakery operations, confectionery manufacturing, and light industrial packaging applications.

Technical Specifications

Key Features and Machine Characteristics

1. Three-Servo Motor Control with PLC Automation

The servo flow wrapping machine utilizes three independent servo motors synchronized through PLC programming for film transport, sealing, and cutting operations. Bag length is set digitally and executed immediately without adjustment cycles, reducing setup time and film consumption. This servo-driven architecture delivers precise motion control, ensuring consistent package dimensions and seal quality throughout production runs.

2. Fiber Optic Automatic Sensing Technology

Advanced fiber optic sensors detect product presence and trigger automatic packaging cycles. When products are fed into the machine, packaging proceeds automatically; when no product is detected, the system enters standby mode. This intelligent sensing capability reduces energy consumption, minimizes wear on mechanical components, and prevents empty bag formation, improving overall equipment efficiency.

3. Self-Diagnostic Fault Detection System

Built-in fault diagnosis functionality monitors system performance and displays error conditions through an intuitive visual interface. Operators can quickly identify issues such as film tracking errors, temperature deviations, or mechanical faults, enabling rapid troubleshooting and minimizing production interruptions. Clear fault indicators reduce the need for specialized technical knowledge during routine operation.

4. High-Sensitivity Photoelectric Color Mark Tracking

Precision photoelectric sensors detect printed registration marks on film substrates with high sensitivity. Digital input for seal-cut positioning ensures accurate seal placement, maintaining consistent package appearance and preventing misaligned cuts. This tracking system accommodates various film types and print qualities, supporting flexible packaging material selection.

5. Independent PID Temperature Control

Separate PID-regulated heating elements for longitudinal and transverse seals allow precise thermal management across different packaging materials. This independent temperature control accommodates polypropylene, polyethylene, laminated films, and specialty substrates, ensuring hermetic seals without film degradation. Operators can adjust temperature parameters to match specific film characteristics and product requirements.

6. Positioning Stop Function

Automated stopping sequence positions sealing jaws in open configuration during production pauses or emergency stops. This positioning stop function prevents adhesive buildup on cutting blades, eliminates film waste, and protects film from heat damage during idle periods. The feature extends blade life and reduces cleaning frequency, lowering maintenance costs.

7. Simplified Transmission System

Streamlined mechanical design with reduced component count enhances system reliability and simplifies routine maintenance. Accessible drive components and tool-free adjustment mechanisms reduce service time requirements. The simplified architecture minimizes potential failure points, supporting consistent operation in demanding production environments.

8. Software-Based Control Platform

All operational parameters and control logic are implemented through programmable software interface. This architecture supports parameter adjustment, recipe storage for multiple products, and seamless integration of future capability enhancements. Software-based control enables remote diagnostics, production data logging, and integration with factory management systems.

Application Areas

Food Industry Packaging Applications

• Snack foods: Puffed snacks, granola bars, energy bars, and portion-controlled snack packs with optional gas flushing for freshness retention

Daily Consumer Goods Packaging

• Household products: Soap bars, cleaning sponges, household cleaning items, and personal care products requiring protective wrapping
• Retail items: Small consumer goods, promotional items, and multi-pack bundling for retail distribution

Hardware and Industrial Parts Packaging

• Hardware tools: Fastener sets, hand tools, automotive accessories, and small component kits requiring protective packaging and product visibility
• Industrial parts: Electronic components, plastic molded parts, metal stampings, O-rings, gaskets, and precision components requiring dust protection and handling protection

Fresh Produce Packaging

• Vegetable and fruit packaging: Vegetable trays, fruit containers, pre-packaged salad boxes, and fresh produce requiring ventilation through punched bag formats

Product Compatibility Requirements

The horizontal flow wrapping machine accommodates regular-shaped products with consistent dimensions, supporting efficient automated feeding and reliable package formation. Products should have stable geometry, appropriate size for horizontal orientation (max. height 80mm), and compatibility with heat-sealable film materials. The system handles solid products across food, consumer goods, hardware, and industrial categories with predictable shapes and sizes.

Bag Format Options

This automatic flow packing machine supports back-seal bags for standard pillow pack configurations, pillow bags for traditional horizontal wrapping, and punched bags for products requiring ventilation or gas release. Optional gas flushing capability enables modified atmosphere packaging for products requiring extended shelf life or oxidation protection, customizable based on specific customer requirements and product characteristics.
