Industrial Continuous & Intermittent Vertical Form Fill Seal (VFFS) Machine
The ZSYAN SY-VFFS Series Vertical Form Fill Seal Packaging Machine is a heavy-duty industrial bagging platform engineered for pillow, gusseted, and block bottom pouch packaging from 10g to 5000g at speeds up to 100 bags per minute. Equipped with dual servo-driven film pull belts, pneumatic horizontal sealing jaws, and high-sensitivity photoelectric eye mark tracking (±1mm accuracy), it delivers hermetic seal integrity across laminated film, pure PE, and recyclable barrier substrates. Constructed with food-grade SUS304 stainless steel and driven by a 7-inch color PLC touchscreen with 99 recipe presets, it seamlessly couples with combination weighers, auger fillers, and piston dosing systems.
Engineering Advantages & Technical Highlights
Precision-machined in Zhongshan, Guangdong with industrial-grade European standard electrical components.
Dual Servo Film Pulling System
Synchronous servo pull belts maintain constant film tension, preventing film slipping and ensuring exact ±1mm bag length registration even at high line speeds.
Continuous & Intermittent Motion Modes
Selectable intermittent jaw motion for standard pouches or continuous box-motion sealing for high-speed pillow bags up to 100 bags/min.
Tool-Less Former Changeover
One-piece stainless steel forming collar allows rapid changeover between different bag widths and pouch styles in under 10 minutes.

Material Suitability & Application Boundaries
Our engineering laboratory verifies physical handling tolerances to prevent jamming, breakage, or product degradation.
✅ Factory-Verified Ideal Applications
- Dry Free-Flowing Granules: Rice, grains, seeds, pet kibble, sugar, salt, dried beans (paired with multihead weigher).
- Fragile Puffed Snacks: Potato chips, extruded snacks, popcorn, pretzels with nitrogen flushing.
- Frozen Food Products: Frozen dumplings, chicken nuggets, frozen peas, shrimp, ice cubes.
❌ Unsuitable Products & Alternative Systems
- Extremely Sticky Non-Flowing Pastes: Without heated auger/piston assist (use our dedicated SY-L piston series).
- Aerated Sub-Micron Fine Powders: Without de-aeration screw (requires our closed-loop auger VFFS machine).
Turnkey Packaging Line Integration Workflow
Seamlessly pair with upstream feeding and downstream end-of-line case packing equipment.
Film Web Unwinding
Motorized reel shaft feeds film with auto tracking sensor alignment.
Collar Pouch Forming
One-piece stainless collar folds flat film into vertical cylinder.
Vertical Lap Sealing
Heated seal bar forms airtight longitudinal back seam.
Dosing & Horizontal Seal
Product drops from weigher while cross-seal jaws cut and hermetically seal.
Takeaway Conveyor
Pouch exits via incline belt to metal detector and checkweigher.
Frequently Asked Questions (FAQ)
Direct answers from our senior packaging machinery engineering team.
Q What bag types can this VFFS machine produce?
Standard pillow pouches, side-gusseted bags, quad-seal box pouches, and pouches with Euro-slot hanging punches or nitrogen gas flushing.
Q Can it run 100% recyclable mono-material PE films?
Yes. We offer low-inertia constant heat seal bars and specialized Teflon anti-stick coatings optimized specifically for 100% recyclable mono-material PE films.
