ZONESUN ZS-FS220UB Automatic Liquid Sachet Packing Machine with Conveyor Belt | High-Speed VFFS Servo Gear Pump Filler for Sauce & Paste

Overview

The ZONESUN ZS-FS220UB is a high-speed automatic liquid sachet packaging machine using a servo gear pump for precise metering and a side/edge sealing VFFS (vertical form-fill-seal) format. An intelligent automatic control system combined with a variable frequency drive (VFD) bag-pulling motor delivers quieter operation, faster throughput, and reduced energy consumption compared to conventional fixed-speed systems. At 60–90 bags per minute with a dosage range of 10–20 g, the ZS-FS220UB is engineered for efficient, stable packaging of liquids, pastes, and sauces across pharmaceutical, daily chemical, food, and agricultural industries.

Applications

The ZONESUN ZS-FS220UB high-speed vertical form-fill-seal (VFFS) packaging machine is specifically engineered for precise metering and automatic sachet packing across a wide viscosity range—from free-flowing liquids to thick pastes and semi-fluid materials.

• Food & Condiment Packaging: Ideal for portion-controlled, single-serve sachet packaging of ketchup, soy sauce, chili oil, salad dressing, mayonnaise, honey, fruit jam, peanut butter, hot pot seasoning base, and liquid spices.
• Personal Care & Cosmetics: Perfect for retail and sample-size packaging of shampoo, hair conditioner, shower gel, facial cleanser, hand sanitizer, moisturizers, skin lotions, and liquid mask essence.
• Beverages & Functional Drinks: High-speed sachet packing for fruit juice concentrates, liquid energy drinks, liquid tea extracts, herbal drinks, and nutritional liquid supplements.
• Pharmaceutical & Nutraceutical: High-precision dosing for oral liquid medicines, syrup doses, liquid probiotics, and health tonic sachets requiring strict weight accuracy and hygienic sealed packaging.
• Agricultural & Daily Chemicals: Safe, reliable single-dose packaging for liquid pesticide concentrates, liquid fertilizers, herbicides, household liquid detergents, and floor cleaners.

CONTROL PANEL

Adopts an intuitive touch interface with integrated indicators and safety buttons to monitor operation status and adjust packaging parameters in real time.

ROLL FILM HOLDER

Holds the packaging film roll and automatically unwinds it under constant tension in real time to ensure smooth, wrinkle-free bag forming.

FORMING & SEALING

Executes precise vertical heat-sealing on the film tube, smoothly pulls it down for liquid filling, and finally performs horizontal sealing in real time.

CUTTING STRUCTURE

Utilizes high-precision mechanical cutters to instantly cut the sealed film tube in real time, separating it into individual finished liquid pouches.

HOPPER

Stores liquid raw materials and works with level sensors to ensure a steady, continuous, and splash-free fluid supply to the filling pump in real time.

DISCHARGE CONVEYOR

Receives individual finished pouches after cutting and utilizes an inclined belted conveyor with cleated flights to steadily transport them to the collection area in real time.

Key Features

• Servo Gear Pump Metering — Precise & Consistent Dosing: Servo-driven gear pump delivers accurate, repeatable fill volumes for liquids and pastes across the 10–20 g dosage range, maintaining consistent fill weight regardless of product viscosity variation — reducing giveaway and ensuring compliance with fill-weight regulations.
• 60–90 Bags/Min High-Speed Output: Continuous automated packaging at up to 90 bags per minute supports high-volume production targets for single-serve sachet formats, significantly reducing per-unit packaging labor cost versus semi-automatic alternatives.
• VFD Bag-Pull Motor — Quieter, Faster & Energy-Efficient: Variable frequency drive controls bag film pulling speed dynamically, reducing mechanical noise, enabling faster acceleration and deceleration between cycles, and lowering energy consumption compared to fixed-speed motor systems.
• Side/Edge Seal VFFS Format: Vertical form-fill-seal with side or edge sealing produces compact, leak-resistant sachets suitable for single-use liquid and paste products — compatible with standard laminated film rolls used across food, cosmetic, and pharmaceutical sachet packaging.
• Intelligent Automatic Control System: Integrated control system monitors and coordinates film feeding, sealing temperature, bag-pull speed, and pump dosing in real time, enabling stable unattended operation and rapid fault detection without constant operator supervision.
• Wide Bag Size Range (20–145 mm × 20–110 mm): Adjustable bag length and width settings accommodate a broad range of single-serve sachet formats without requiring mechanical tooling changes — enabling multi-SKU production on a single machine.
• Low Power Consumption — 2 kW: Despite high-speed output, the ZS-FS220UB operates at just 2 kW total power draw, keeping energy costs low during extended production shifts.
• Compact Industrial Footprint (900 × 700 × 1720 mm): Slim upright VFFS design minimizes floor space usage while delivering full high-speed sachet packaging capability, suitable for facilities with limited production floor area.

Applications
