The Grand Machinery Vertical Form Fill Seal Machine turns roll-stock film into perfectly sealed, retail-ready pouches at up to 90 bags per minute — one machine handling powders, granules, and small solids around the clock. Precision servo-driven motion, hygienic 304 stainless steel construction, and CE-certified engineering come as standard, backed by one trusted partner from sample testing to after-sales support.
The Grand Machinery VFFS range offers three models—the GM320B, GM520B, and GM720B—designed to handle varying film widths, speeds, and capacities from small batches to large-format packaging.
The GM720B Vertical Form Fill Seal Machine (VFFS) features a robust 304 stainless steel body, and supports a maximum dosing range of 4000 ml and packaging speeds up to 50 bags/min, making it ideal for various large-format packaging applications. GM720B VFFS is an advanced packaging solution designed for high efficiency and precision.
The GM520B is a high-capacity Vertical Form Fill Seal (VFFS) machine designed for efficient automated packaging, delivering a speed of 5-60 bags/min. It accommodates a max film width of 520 mm, a measuring range up to 2000 ml, and bag dimensions of 80-400 mm in length and 80-250 mm in width, built with a durable 304 stainless steel frame.
The GM320B Vertical Form Fill Seal machine (VFFS) is designed for automated packaging, offering a flexible packaging speed of 5-90 bags/min depending on the material. It accommodates a max film width of 320 mm, a measuring range of 50-800 ml, and bag lengths from 50-200 mm with widths from 50-150 mm, built with a durable 304 stainless steel structure.

Five engineering decisions set our machines apart — and all of them show up directly in your bottom line: less film waste, fewer stoppages, lower labor cost per bag.
Independent servo drives on film pull, sealers, and cutter deliver ±0.5 mm sealing position accuracy and 30% less film waste than cam-driven machines.
Quick-release forming collars and memory-stored recipes cut SKU changeover time to under 10 minutes.
Open-frame design, sloped surfaces, and IP65-rated washdown options meet the strictest food-safety audits.
Ethernet and OPC-UA connectivity for remote monitoring, OEE dashboards, and predictive maintenance alerts.
In-house design, testing with your actual product and film before shipment, and a 24-month warranty.
The working process of vertical form fill seal machine is elegantly simple: flat film enters, a finished sealed pouch exits, and every step in between is synchronized by servo motion for repeatable accuracy. Here is how each cycle unfolds:
Roll stock film is fed from the unwind station with an automatic tension control system and photocell registration, keeping printed artwork perfectly centered on every single pouch.
Film is drawn around a forming collar and sealed at the bottom by the horizontal sealer, creating the bag body — pillow, gusseted, or quad-seal — to match your product and shelf presentation.
Your chosen dosing system — multihead weigher for granules, auger filler for powders, or volumetric cups — releases the precise target weight directly into the open pouch.
The vertical sealer closes the pouch airtight; an optional date coder prints batch and expiry data inline, and the finished bag is cut and discharged, ready for case packing — a complete cycle your vertical form fill seal machine repeats up to 90 times per minute.

Straight answers from our engineers for vertical form fill machines. If your question isn’t covered below, our technical team responds to all inquiries within 12 working hours.
Our vertical form fill seal machines pack free-flowing and non-free-flowing products across three main solid categories: powders (flour, milk powder, spice blends, protein powder), granules (sugar, salt, rice, coffee beans, pet food kibble), and small solids (candy, nuts, hardware). Flowable liquids and pastes are covered by a dedicated piston-filling configuration, explained further below. Tell us your product’s bulk density and target weight, and we’ll recommend the right dosing system.
It runs all heat-sealable laminated films, including PET/PE, PET/AL/PE, OPP/CPP, and recyclable mono-material structures. Supported bag styles include pillow bags, gusseted bags, quad-seal bags, stick packs, and pouches with hole punches or Euro-slot openings — change styles simply by swapping the forming collar and sealing jaws.
Speed depends on the model and dosing system: the GM320B runs 5–90 bags per minute, the GM520B covers 5–60 bags per minute, and the GM720B reaches up to 50 bags per minute on large-format bags. Filling accuracy is typically ±0.5–1.5% depending on product characteristics, validated during Factory Acceptance Testing before shipment.
Yes. Our automatic vertical form fill seal machine connects upstream to conveyors, elevators, and product feeders, and downstream to checkweighers, metal detectors, nitrogen flush systems, and case packers. We provide a full line layout drawing and synchronized PLC handshaking so the whole line runs as one seamless system.
Every machine ships with remote video commissioning and operator training, and optional on-site engineer installation is available worldwide. Critical spare parts are stocked for same-week dispatch, and our engineering team provides lifetime technical support with a 24-month machine warranty.
Each vertical form fill seal machine is offered with four dosing platforms: multihead weighers for free-flowing granules and snacks, auger fillers for fine or aerated powders, volumetric cup fillers for uniform products on a tighter budget, and piston fillers for liquids. The deciding factors are your product’s flow behavior, target weight, and accuracy requirement — describe your product, and our engineers will specify the right system and verify it with sample tests before production.
Yes. With an optional piston or peristaltic filling module, the GM series seals sauces, dressings, oils, and other flowable products into leak-proof pouches. For fine powders that tend to bridge or stick inside the filler, we recommend an auger filler with agitator — we’ll match the filling technology to your product’s density and moisture content.
Absolutely. For oxygen-sensitive products such as roasted coffee, nuts, and snacks, an integrated nitrogen flush system displaces oxygen inside the pouch before sealing, extending shelf life without additives. Flush parameters are saved within each product recipe and switch automatically during changeover.
All GM models run on single- or three-phase power — 220 V, 380 V, or 415 V, 50/60 Hz selectable — and need a clean compressed air supply at approximately 0.6 MPa. Footprint varies by model and dosing system; configurations with a multihead weigher require extra headroom for the weigher hopper. A detailed installation drawing is included with every quotation.
Yes — thermal transfer or inkjet coders mount after the sealing station to print expiry dates, batch numbers, and traceability codes on every pouch. Coder settings are stored within each recipe, so codes update automatically whenever an operator recalls a saved product setup.
We encourage it. Send us your product and film samples, and our lab will run filling and sealing trials to verify speed, weight accuracy, and seal strength — you’ll receive a video report before we start production. For larger projects, you are welcome to attend Factory Acceptance Testing before shipment.
