5–25L Industrial Automatic VFFS Pouch Machine with Online Spout & Screw Cap Inserting

1. Product Overview

This industrial-grade, heavy-duty Vertical Form Fill Seal (VFFS) liquid packaging machinery is meticulously engineered for large-scale bulk applications ranging from 5L to 25L requiring an integrated spout or screw cap. Optimized for thick, multi-layer laminated (composite) films, this advanced single-lane, back-sealing (center sealing) system features a cutting-edge online fitment application system that seamlessly forms the pouch and installs screw caps or spouts in one continuous high-speed process, drastically cutting material costs and manual labor.

The system delivers a fully automated manufacturing loop—including extra-wide roll film bag forming, synchronized online screw cap adding/spout insertion, high-precision volumetric or flow-meter dosing, heavy-flow fluid filling, reinforced thermal sealing, cold cutting, date coding, mark detection, and batch counting. Operating at a stable, high-mass speed of up to 6 bags/minute, it provides an ultra-secure, leak-proof turnkey solution for institutional catering, bag-in-box (BIB) supply chains, liquid egg processing, edible oils, and industrial fluid bulk packaging.

3. Technical Features

• Innovative Online Screw Capping / Spout System: The machinery automatically punches, aligns, and seals plastic screw caps or spouts online directly during the continuous roll film bag-making cycle. This eliminates the need for expensive pre-made spouted bags, significantly lowering packaging material overhead and eliminating manual insertion labor.

• Fully Customizable Volume Capacity: Highly adaptable structural framework and film-pulling design, customized precisely to match your required packaging volume boundaries and target film width metrics.

• Reinforced Multi-Blade Heavy-Load Sealing: Specifically calibrated to handle the extreme static weight and hydraulic forces of up to 25kg liquid loads. Combining precise PID temperature control and a constant heat sealing with precise cold cutting method, it employs an advanced multi-seal-blade design that creates ultra-strong, leak-proof fused welds on thick barrier laminates. A safety interlock shuts off filling if the jaws deviate by ±5°C.

• Stepless Height Adjustability: The horizontal sealing assembly permits stepless height adjustments within a designated range, allowing your facility operators to execute rapid changeovers between different bulk pouch sizes and lengths.

• Dual-Option High-Precision Filling Systems: Configured precisely to match the physical flow traits of your specific product:

  1. Pneumatic Cut-off Valve + Float Switch Loop: Regulates consistent fluid levels inside the balance tank (with low-level alarms) and fine-tunes dosing via a mechanical rotary adjustment knob.

  2. Digital Flow Meter + Supply Pump Loop: Allows operators to adjust and input filling volumes digitally directly on the touch screen interface, paired with a micro-adjustment rotary knob for flow optimization.

• Smart Control Architecture: Driven by a premium integrated PLC system and an intuitive HMI touch screen panel for centralized parameter editing, live statistics monitoring, and simplified troubleshooting.

• High-Torque Servo Film Feeding: The heavy-duty film pulling network is driven and monitored by a high-torque servo motor to guarantee silky-smooth web tension under extreme loads, complete with an automated film-shortage safety alarm.

• Heavy-Duty Transmission Main Drive: Synchronized by a premium combination of a servo motor, high-ratio reducer, and large-bore pneumatic cylinders to ensure smooth, zero-slippage mechanical transmission during high-mass operations.

• Class 100 Clean Laminar Flow Hood (Optional): The interior processing environment can be fully enclosed and blanketed with a positive pressure of Class 100 purified air to achieve an ultra-clean packaging zone.

• UV Web Sterilization: Integrated high-intensity UV lamps sterilize the packaging film prior to bag forming. A built-in safety switch automatically deactivates the UV light if the chamber door is opened, protecting operators’ eyes.

• CIP Automatic Cleaning Ready: Fully supports Clean-In-Place (CIP) automatic circulation loops. The entire internal manifold interfaces seamlessly with your facility’s existing central CIP infrastructure for effortless sanitation.

• Pinpoint Registration Mark Detection: A high-sensitivity photoelectric sensor tracks color marks on the film in real time, synchronizing the servo system to guarantee precise bag length and complete pattern integrity.

• Rigorous Hygienic Standards: Structural frame components are manufactured from premium SUS304 stainless steel. All internal product-contact piping and feed parts are constructed from medical-grade SUS316L stainless steel, offering superior corrosion, acid, alkali, and absorption resistance.

• Logistics & Utilities: Tracks and displays live pouch counts directly on the main HMI screen. Standard configuration includes a built-in air blow gun for daily maintenance and a dedicated electronic scale communication socket.

4. Optional Configurations

• Integrated Class 100 Clean Laminar Flow Hood: Creates a positive-pressure, ultra-clean environment inside the machine for strict hygienic processing of dairy or pasteurized bulk liquids.

• Customized Screw Cap or Spout Tooling: Tailored application heads designed around your specific closure geometry, diameters, and thread specifications.

• Servo Rotor Pump: Positioned on the filling pipeline after the balance tank; highly recommended for handling high-viscosity bulk materials (such as dense pastes, sauces, fruit purees, or creams).

• Product Supply Feed Pump: Placed before the balance tank to transfer material automatically from your main storage; tailored based on specific product characteristics.

• Multi-Language HMI Touch Screen: Localized operating system interface language customized to your global factory operators’ preferences.

5. Product FAQ

Q1: What is the main financial advantage of the online screw capping system?

A: Traditional bulk liquid packaging requires buying expensive pre-made bags that already have spouts welded onto them. Our machine builds the bag directly from standard roll film and welds the plastic spout/screw cap online in real-time. This reduces your raw packaging material costs by up to 30–50% and completely eliminates the need for manual bag feeding, delivering an immense return on investment (ROI).

Q2: How does the machine secure heavy bulk pouches up to 25L against leaking at the spout?

A: A 25L liquid pouch suffers heavy hydraulic stress, especially around the rigid plastic spout interface. Our system utilizes precise ultrasonic or customized heavy-duty thermal weld matrices with PID control around the spout flange, combined with a multi-seal-blade design for the pouch’s back and horizontal seals. This creates a deeply fused bond between the laminated film and the spout, ensuring 100% leak-proof security under heavy drop and shipping tests.

Q3: Can the same machine adjust to handle both a 5L pouch and a 25L pouch?

A: Yes. The machine features an adjustable horizontal sealing unit with stepless height adjustment, and accommodates wide web profiles (730–810mm film width for 5–12L setups, and 810–970mm width for 10–25L setups). By changing the film roll and adjusting the digital filling parameters on the HMI touch screen, you can smoothly move between bulk sizing.

Q4: Is the digital Flow Meter system better for bulk institutional packaging?

A: Yes, highly recommended. When dealing with high volumes up to 25L, the Flow Meter + Supply Pump configuration allows operators to change batch targets instantly on the HMI screen (e.g., from 10,000ml up to 25,000ml) with a strict accuracy of ±0.5%. It removes the downtime of adjusting mechanical rotary dials and ensures fast, continuous filling.

Q5: Can this machine be integrated with an automated box loader for Bag-in-Box (BIB) production?

A: Absolutely. This machine is the ideal cornerstone for high-capacity Bag-in-Box (BIB) packaging lines. Once the pouches are formed, online-spouted, filled, and cut, they can be flawlessly transferred via a discharge conveyor directly into automated carton-erecting and box-loading systems for commercial distribution.
