Overview of Vertical Form-Fill-Seal Packing Machine (VFFS)
Vertical Form-Fill-Seal (VFFS) machines are the industry standard for high-speed, efficient packaging (hardware, furniture fittings, and small parts). These versatile systems transform a continuous roll of film into sealed pouches, fill them with product, and complete the process in one seamless vertical workflow.
How Our VFFS Packing Machine Works: Step-by-Step Breakdown
Automatic VFFS packing machines operate in continuous or intermittent cycles (tailored to your product type) to turn flat film into ready-to-ship pouches:
VFFS packing machines operate in continuous or intermittent cycles (tailored to your product type) to turn flat film into ready-to-ship pouches:
Step 1: Film Unwinding: Roll stock (PE, PP, laminates, paper film) feeds from a reel with customizable widths—compatible with eco-friendly films (e.g., paper-based materials) for sustainable hardware/furniture fitting packaging.
Step 2: Tube Forming: Film wraps around a forming tube/collar, creating a vertical tube (sealed longitudinally at the back) to contain products like small screws or furniture connectors.
Step 3: Bottom Sealing: Heated jaws seal the pouch bottom, creating a secure base before filling—critical for preventing hardware parts (e.g., sharp screws) from puncturing the pouch.
Step 4: Product Filling: Dosing systems (multihead weigher, auger, or our vibratory bowl counting machine) drop precise amounts into the tube. For hardware packaging: 100 screws (counted via upstream vibratory feeders) are deposited into the pouch with 99.9% accuracy.
Step 5: Top Sealing: Jaws seal the pouch top—simultaneously forming the bottom seal for the next pouch to maximize speed (no downtime between cycles).
Step 6: Cutting & Finishing: A precision knife cuts the pouch; optional add-ons (like our heat transfer printing machine) add batch codes, part numbers, or tear notches (ideal for retail hardware pouches). Gas flush (N2) is available for moisture-sensitive products (e.g., potato chips).
Step 7: Ejection: Finished pouches exit via conveyor—ready to be sent to our case sealing machine or palletizing robot for backend packaging.
Core Applications
Our VFFS machine excels in packaging the small parts central to our clients’ businesses:
Hardware Packaging: Pack screws, nuts, bolts, and washers into retail-ready or bulk pouches—paired with our automatic screw packing machine for end-to-end screw packaging lines.
Furniture Fittings Packaging: Seal furniture connectors, dowels, and hinge screws into kits (e.g., 5 dowels + 10 screws per RTA furniture pouch)—ensuring no missing parts (critical for customer satisfaction).
Granules & Powders: Handle non-hardware products (e.g., construction adhesives, snack mixes) with auger or multihead weigher dosing systems.
