Product Definition

The Large Scale Automatic Liquid Vertical Packaging Machine for Max Bag Length 400mm is a specialized vertical form-fill-seal packaging system engineered specifically for large-format liquid and paste products requiring substantial bag dimensions. The machine performs three core functions in a single continuous operation: forming large bags from flat rollstock film, filling them with precisely measured liquid or paste product, and sealing them ready for distribution.

The machine operates on the vertical principle – film is drawn from a roll, formed into a large tube around a filling tube, sealed vertically, filled with liquid or paste from above through a precision dosing system, and sealed horizontally at the bottom and top to create finished bags. With a maximum bag length of 400mm, the machine is specifically designed for large-format liquid packaging applications such as institutional foodservice soup bags, bulk sauce packaging, large cosmetic containers, and industrial liquid detergent packaging.

The machine handles a wide range of viscosities from pure liquids to high-viscosity pastes, with the squeeze exhaust packaging method ensuring proper filling and sealing across different product characteristics. The robust construction and imported electrical and pneumatic components ensure reliable operation even under demanding production conditions, while the independent seal design provides superior sealing integrity essential for liquid packaging.

Technical Specs

Operational Simplicity

The Large Scale Automatic Liquid Vertical Packaging Machine for Max Bag Length 400mm is designed with the operator in mind, ensuring minimal training requirements and maximum ease of use even for large-format packaging operations.

The machine features a multi-language touchscreen HMI that provides clear, user-friendly operation with real-time production status visibility. Operators can monitor production parameters, adjust settings, and access diagnostic information through intuitive interfaces, with language options supporting diverse international workforces. The PLC centralized control system streamlines all machine functions into a single, accessible control point, reducing the complexity of machine operation.

The film feeding mechanism features a humanized design that simplifies film loading and changeover. Operators can easily thread new film rolls without complex procedures, reducing setup time and minimizing film waste during changeovers. This user-friendly design is particularly valuable for large-format film rolls, which can be heavier and more challenging to handle.

The squeeze exhaust packaging method provides consistent filling performance across a wide range of product viscosities, reducing the need for operator adjustments when switching between different liquid products. The machine's ability to handle diverse viscosities without complex reconfiguration simplifies product changeovers and reduces operator intervention.

Parameter adjustments for bag length, bag width, filling volume, and sealing temperature can be made directly through the touchscreen interface without requiring mechanical changes. Multiple product recipes can be stored and recalled, enabling rapid changeovers between different products and bag configurations with consistent quality across every production run.

The simple, clean mechanical structure reduces operational difficulty and simplifies maintenance. The robust construction ensures stable operation with minimal operator attention, while the independent seal design and imported components provide reliable performance that requires less frequent adjustments compared with conventional designs.

Rejection Rate & Quality Control

The Large Scale Automatic Liquid Vertical Packaging Machine for Max Bag Length 400mm is engineered to minimize product defects and maximize packaging yield through multiple quality control mechanisms, which is particularly critical for large-format liquid packaging where product and material costs are significant.

The machine features excellent sealing performance with clear, rapid seals that maintain integrity even with liquid and paste products. The independent seal design ensures consistent seal quality across different products and operating conditions, preventing leaks that would lead to package rejection and product waste. This is particularly important for large-format liquid packaging where seal failure could result in significant product loss and potential contamination of surrounding packages.

The squeeze exhaust packaging method ensures proper filling and sealing across different product viscosities, with the exhaust mechanism removing air from the bag before sealing to prevent premature spoilage and ensure proper bag shape. This method also reduces the risk of seal contamination from product residue that could compromise seal integrity.

The imported electrical and pneumatic components provide reliable, consistent performance that minimizes defects caused by component variability or failure. The robust construction ensures stable operation that maintains consistent quality across extended production runs, reducing the risk of quality drift that could lead to rejects.

The PLC control system and fault tracking alarm system continuously monitor machine performance, detecting irregularities in sealing temperature, film tension, and filling accuracy. The system provides immediate alerts for operational issues, enabling operators to correct problems before they result in rejections.

The machine's stable operation with low noise indicates consistent mechanical performance that contributes to reliable packaging quality. The compact, vibration-resistant design ensures that components maintain proper alignment even during high-speed operation, preventing defects caused by mechanical misalignment.

The user-friendly design simplifies changeover procedures, reducing the risk of operator errors that could lead to rejects during product transitions. Stored recipes ensure consistent parameter settings across changeovers, maintaining quality standards even when switching between different products.

Automation & Smart Control

The Large Scale Automatic Liquid Vertical Packaging Machine for Max Bag Length 400mm features a sophisticated control architecture that ensures reliable, intelligent operation for demanding large-format liquid packaging applications.

The PLC centralized control system provides comprehensive management of all machine functions including film feeding, filling, sealing, and cutting operations. This centralized approach simplifies operation and troubleshooting while enabling coordinated control of all machine functions for consistent, reliable performance.

The multi-language touchscreen HMI provides intuitive operation and real-time production monitoring. Operators can view production status, adjust parameters, and access diagnostic information through the user-friendly interface, with multiple language options supporting international workforces and diverse market requirements.

The integrated fault tracking alarm system provides immediate alerts for operational issues, enabling rapid response to problems before they cause significant downtime or defects. The system monitors critical parameters including sealing temperature, film tension, and filling accuracy, providing early warnings that enable proactive maintenance and quality control.

The machine can be optimally combined with multiple forms of filling systems, providing flexibility for different liquid products and packaging requirements. The control system coordinates with these filling systems to ensure precise dosing and synchronized operation, maintaining consistent fill weights across all packaging runs.

The independent seal design with imported electrical and pneumatic components provides reliable, consistent sealing performance controlled by the automation system. The sealing parameters can be precisely adjusted through the PLC, ensuring optimal sealing quality for different film types and product characteristics.

The squeeze exhaust packaging method is integrated with the automation system, with filling parameters automatically adjusted to ensure proper exhaust and filling across different product viscosities. This integrated approach ensures consistent packaging quality with minimal operator intervention, reducing the potential for human error and improving overall production efficiency.
