SYB/SJYB-ⅢSD-F Automatic Laminated Film Double-Head Liquid Packaging Machine

1. Product Overview

The SYB/SJYB-ⅢSD-F is a heavy-duty, high-speed, fully automatic Vertical Form Fill Seal (VFFS) liquid packaging machinery explicitly engineered for laminated films (composite films). Designed for premium liquid and viscous products that demand strict high-barrier properties, superior oxygen resistance, and exceptional packaging strength, this system delivers industrial-grade security against leaks and spoilage.

Featuring an advanced dual-head filling architecture, the machine seamlessly automates the continuous production cycle—including roll film bag forming, high-precision volumetric metering, filling, back-sealing (center sealing), cold cutting, date coding, registration mark detection, and batch counting. Operating at an optimized capacity of up to 90 bags/minute, the SYB/SJYB-ⅢSD-F ensures pinpoint dosing accuracy and perfectly sealed, retail-ready pouches with flawless pattern integrity.

3. Technical Features

• Optimized Nylon/Laminated Film Heat Sealing: Specially engineered for thick and heavy-duty composite films (such as Nylon laminates). It features a multi-seal-blade design that drastically enhances seal strength and prevents channel leaks. The adjustable horizontal sealing unit offers stepless height adjustment, enabling rapid, toolless changeover between different package specifications.

• Advanced Thermal Control & Cold Cutting: Utilizing intelligent PID temperature control, the system employs a constant heat sealing and precise cold cutting method. If the sealing head temperature deviates by even ±5°C from the normal range, a built-in safety interlock triggers an automatic alarm and halts filling immediately.

• Class 100 Clean Laminar Flow Hood (Optional): The filling and forming zones can be fully enclosed and protected by a Class 100 positive-pressure purified air system, ensuring ultra-hygienic processing.

• Smart PLC & HMI Interface: Controlled via a fully integrated PLC architecture and an intuitive HMI touch screen interface for real-time monitoring and parameter editing.

• Servo-Driven Film Feeding System: Driven by a premium servo motor, the film pulling system ensures silky-smooth web tension. It comes equipped with an automated film-shortage alarm and an external web-guiding device for flawless tracking.

• High-Torque Main Drive Transmission: Powered by a heavy-duty combination of a servo motor, precision reducer, and reliable pneumatic cylinders, guaranteeing stable mechanical synchronization.

• Intelligent Volumetric Filling System: A pneumatic cut-off valve regulates product supply into the balance tank, where a float switch monitors fluid levels (complete with a low-level safety alarm). Filling volumes are easily fine-tuned via an adjustable rotary dial.

• UV Film Sterilization: Integrated high-intensity UV lamps sterilize the packaging film prior to forming. A safety interlock automatically shuts off the UV light if the chamber door is opened to protect operators’ eyes.

• CIP Automatic Cleaning Ready: Fully supports Clean-In-Place (CIP) automatic circulation. The machine seamlessly interfaces with the client’s existing central CIP infrastructure for effortless sanitation.

• Pinpoint Registration Mark Detection: A high-precision photoelectric sensor reads eye-marks on the film in real time, synchronizing the servo motor to guarantee perfect bag-length accuracy and graphics alignment.

• Independent Dual-Lane Control (A & B Positions): Lanes A and B feature independent production control units, allowing operators to run or configure separate packaging parameters for maximum operational flexibility.

• Rigorous Hygienic Standards: Structural frame components are manufactured from premium SUS304 stainless steel. All product-contact piping and parts are constructed from medical-grade SUS316L stainless steel (acid, alkali, and corrosion-resistant).

• Production Logistics: Live production counts are accurately tracked and displayed directly on the touch screen. The unit also 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 (For strict aseptic requirements)

• Servo Rotor Pump (Installed post-balance tank; highly recommended for highly viscous pastes, oils, and thick sauces)

• Product Supply Feed Pump (Installed pre-balance tank to automate material transfer from storage; supports automated gravity-feeding configurations)

• Multi-Language HMI Touch Screen Interface (Customized to regional language preferences)

• Flexible Lane Configurations (Available in single-head filling or dual-head filling setups)

• Fully Customized Tooling & Engineering Tailored to Your Factory Layout

5. Product FAQ

Q1: What makes the “F Type” different from standard liquid packaging machines?

A: The SYB/SJYB-ⅢSD-F (F Type) is specifically reinforced for laminated and multi-layer composite films (like Nylon/PE). Standard liquid machines often struggle to seal thicker barrier films consistently. The F Type features an advanced multi-seal-blade design and a heavy-duty mechanical structure to deliver the intense pressure and precise thermal sealing required for high-barrier packaging, ensuring absolute protection against oxygen and leakage.

Q2: Can this machine handle highly viscous products, and how is the accuracy maintained?

A: Yes. While the standard volumetric gravity-filling system is perfect for free-flowing fluids, we offer an optional servo rotor pump for thick or viscous materials (such as heavy sauces, creams, or oils). The machine locks in a high dosing accuracy of ±0.5% – 1% via a precision cylinder-driven flow control valve and an intelligent balance tank level switch.

Q3: How does the multi-seal-blade design and adjustable horizontal sealing unit benefit our production?

A: Thick laminated films require specialized thermal profiles. The multi-seal-blade design applies multiple distinct sealing bars to create a flawless, ultra-strong back seal. Additionally, the horizontal sealing unit features stepless height adjustment, meaning your operators can change pouch lengths and product specifications rapidly without needing to replace expensive mechanical tooling, significantly reducing changeover downtime.

Q4: Can Lanes A and B run different products or parameters at the same time?

A: Yes. The SYB/SJYB-ⅢSD-F is built with independent production control units for Position A and Position B. You can adjust the filling volumes, sealing speeds, or specific packaging parameters for each lane independently via the HMI touch screen. This unique feature ensures that if one lane requires maintenance or a roll change, the other lane can continue running, preserving factory throughput.

Q5: Is the system compatible with existing factory Clean-In-Place (CIP) systems?

A: Absolutely. Hygiene is a paramount priority for high-barrier liquid filling. All product-contact components are manufactured from premium SUS316L stainless steel which is highly resistant to acids and alkalis. The system fully supports integration with automatic CIP circulation cleaning loops, allowing you to sanitize the entire internal feeding pipeline without tearing down the machinery.
