1–5L Large-Volume Automatic Laminated Film Liquid Packaging Machine

1. Product Overview

This industrial-grade, heavy-duty Vertical Form Fill Seal (VFFS) liquid packaging system is meticulously engineered for large-volume applications ranging from 1L to 5L. Optimized for multi-layer laminated (composite) films, this machine provides maximum seal integrity, superior oxygen isolation, and exceptional puncture resistance, making it the perfect turnkey solution for high-barrier liquid and viscous products.

The equipment features a robust single-lane, back-sealing (center sealing) architecture that fully automates the comprehensive production flow—including roll film bag forming, precision volumetric or flow-meter dosing, product filling, secure thermal sealing, cold cutting, synchronized date coding, registration mark detection, and automated batch counting. Delivering a highly stable and structural output of up to 15 bags/minute, it offers bulk fluid manufacturers unparalleled sealing strength, pinpoint metering accuracy, and effortless changeovers.

3. Technical Features

• Reinforced Multi-Blade Heat Sealing System: Specially calibrated for heavy bulk packages, utilizing smart PID temperature control and constant heat sealing with a precise cold cutting method. Features an advanced multi-seal-blade design to boost seal strength and eliminate channel leaks in thick laminated films. A built-in safety safety system halts filling and triggers an alarm if the sealing temperature fluctuates beyond ±5°C.

• Flexible Stepless Height Adjustability: The horizontal sealing unit features stepless height adjustment within a specified range, allowing operators to rapidly change package specifications and film lengths without major mechanical tear-downs.

• Dual-Option Intelligent Filling Systems: The filling mechanism can be customized to match your product’s unique physical characteristics:

  1. Pneumatic Cut-off Valve + Float Switch Type: Regulates consistent fluid levels within the balance tank (with low-level alarms) and fine-tunes volume via an intuitive mechanical adjustment rotary knob.

  2. High-Precision Flow Meter + Supply Pump Type: Allows direct digital input and adjustment of the filling volume on the touch screen, complete with a micro-adjustment rotary knob for flow optimization.

• Smart Control Interface: Driven by an integrated PLC architecture and an intuitive HMI touch screen panel for unified parameter setup, live statistics tracking, and simplified troubleshooting.

• Servo-Driven Web Tension Control: The film feeding system is driven and monitored by a high-torque servo motor, ensuring ultra-smooth film pulling. Equipped with an automated film-shortage safety alarm.

• Heavy-Duty Transmission Main Drive: Synchronized by a premium combination of a servo motor, structural reducer, and pneumatic cylinders to ensure smooth mechanical transmission under heavy liquid loads.

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

• UV Film Sterilization: High-intensity UV lamps irradiate and sterilize the film prior to pouch forming. An automated interlock shuts off the UV lamp instantly if the chamber door is opened to ensure operator safety.

• CIP Automatic Cleaning Ready: Supports Clean-In-Place (CIP) automatic circulation loops, interfacing seamlessly with your facility’s central CIP infrastructure for teardown-free sanitation.

• Registration Mark Eye-Mark Detection: A high-sensitivity photoelectric sensor tracks color marks on the film in real time, synchronizing the servo system for millimeter-accurate bag length and complete pattern integrity.

• Rigorous Hygienic & Structural Standards: Structural frame parts are built from premium SUS304 stainless steel. All fluid-contact pipelines and feed parts are crafted from medical-grade SUS316L stainless steel (acid, alkali, and corrosion-resistant).

• Logistics & Utilities: Displays live pouch counts on the HMI. Includes a built-in air blow gun for routine maintenance and a dedicated electronic scale communication socket.

4. Optional Configurations

• Integrated Class 100 Clean Laminar Flow Hood: For facilities requiring strict ultra-clean or aseptic processing environments.

• Servo Rotor Pump: Placed post-balance tank on the filling pipeline; highly recommended for handling high-viscosity bulk materials (pastes, heavy oils, purees, and thick sauces).

• Product Supply Feed Pump: Positioned upstream to automate fluid transfer from bulk storage to the machine’s balance tank, selected based on your specific product layout.

• Multi-Language HMI Touch Screen: Custom localized user interface text tailored to your regional operators’ habits.

5. Product FAQ

Q1: How does this machine ensure seal security for heavy packages up to 5L?

A: Packaging 1L to 5L of liquid puts immense stress on film seams. To prevent ruptures and leaks, our machine utilizes a specialized multi-seal-blade design combined with high-pressure pneumatic cylinders and precise PID thermal control. This applies deep, uniform multi-layered weld seals across laminated composite films, providing the extreme packaging strength and gas-tight sealing required for bulk shipping.

Q2: What are the benefits of the alternative Flow Meter filling configuration?

A: For large-volume changes (e.g., switching from a 2L batch to a 5L batch), the Flow Meter + Supply Pump system allows operators to type the desired volume directly into the HMI touch screen. This completely eliminates manual mechanical tuning, cuts changeover downtime down to seconds, and maintains a strict dosing accuracy of ±0.5%.

Q3: Can the same machine handle different pouch sizes and volumes?

A: Yes, easily. The machine accommodates film widths from 350mm to 620mm. It features an adjustable horizontal sealing unit with stepless height adjustment, allowing you to change both the length and width of the bags smoothly to accommodate any fluid volume within the 1000ml to 5000ml range.

Q4: Is this bulk liquid filler compatible with automatic CIP systems?

A: Yes. To fulfill international food safety and chemical safety criteria, all product-contact piping and valves are engineered from medical-grade SUS316L stainless steel, which resists corrosive cleanings, acids, and alkalis. The entire fluid manifold is CIP-ready, docking directly with your factory’s automated cleaning loop for hands-free flushing.

Q5: Can it fill thick or viscous products like industrial sauces, oils, or pastes?

A: Absolutely. While the standard pneumatic valve configuration is built for free-flowing liquids, you can seamlessly add our optional servo rotor pump. This positive-displacement configuration effortlessly moves dense, high-viscosity materials into the multi-layer pouches without clogging or dripping.
