How VFFS machines work and what they produce
A VFFS (vertical form fill seal) machine forms bags from a flat film roll, fills them with product, and seals and cuts them — entirely automatically. The VFFS process: flat film from a roll is fed over a forming shoulder that wraps it into a tube around a vertical fill tube; a longitudinal fin seal or lap seal joins the film edges to form a continuous tube; a cross-sealing jaw creates the bottom seal of the next bag while simultaneously creating the top seal of the previous bag and cutting the bags apart; product is dispensed through the fill tube (open at the top) into the bag cavity before the cross seal closes. The result is a filled and sealed bag produced at high speed from a roll of flat film. VFFS machines produce a wide range of bag styles: pillow pouch — the standard flat-sided bag; gusset bag — a bag with side gussets for better stability; block-bottom bag — a bag with a flat bottom that stands upright; quad-seal bag — a bag with four vertical seals and a flat bottom, used for premium coffee and pet food. VFFS machines are used across a wide range of applications: snacks (crisps, popcorn, puffed snacks) — typically with a multihead weigher above; nuts, seeds, dried fruit — multihead weigher; frozen vegetables and frozen food portions — multihead weigher or linear weigher; ground coffee and whole bean coffee — auger filler or linear weigher; powders (flour, spices, protein powder, dry chemicals) — auger filler or volumetric cup filler; liquids and pastes (sauces, dairy products) — piston or pump filler; granular products (sugar, rice, pulses) — cup filler or multihead weigher; sachets (single-serve portions of sugar, tea, spices) — auger filler in multi-lane configurations.
Film materials, speed, and sourcing
VFFS machines run on a wide range of packaging films, which must be selected to match the product requirements. Common VFFS films: PE (polyethylene) — basic barrier for snacks, frozen food, grain; standard, low cost. OPP/LDPE (oriented polypropylene/polyethylene laminate) — better moisture barrier and stiffness; standard for biscuits, confectionery. PA/PE (nylon/PE laminate) — high oxygen barrier; for coffee, meat, and oxygen-sensitive products. PP/EVOH/PE — premium oxygen barrier for long shelf life applications. Metallised films — printed metalised OPP or PET laminates for premium snack packs. Compostable PLA films — available for sustainable packaging initiatives. The film roll width determines the bag circumference; the film must run consistently on the VFFS machine's forming system. Output speed of VFFS machines: for dry granule applications with a multihead weigher, 30–100 bags per minute is typical for a standard machine; sachet machines in multi-lane configuration can produce several hundred sachets per minute; liquid VFFS at lower speeds due to fill time constraints. Key VFFS machine suppliers: Ishida and Hayssen (US/Japan), ILAPAK (Switzerland), Rovema (Germany), and a large number of Chinese manufacturers for standard food packing applications at competitive pricing. When sourcing, specify: product type and consistency, dosing method (multihead weigher, auger, piston, pump), target bag style, bag dimensions (width, length, gusset depth), film type, required output speed, sealing jaw type (standard or rotary), and TTO integration if coding on film is required.
Frequently asked questions
What is the difference between a fin seal and a lap seal on a VFFS machine?
The longitudinal (vertical) seal on a VFFS pillow bag is made by joining the two edges of the flat film tube. In a fin seal (also called a flat seal or fin weld), both film edges are folded together and sealed face-to-face, creating a fin that projects outward from the bag. In a lap seal, one film edge overlaps the other and the inside surface of one edge is sealed to the outside surface of the other, creating a flat profile. Fin seals are more common and easier to produce; lap seals are preferred for clear bags where the seal visibility matters or for certain film types that require a lap seal for structural reasons.
Can a VFFS machine produce stand-up pouches?
A standard VFFS machine produces pillow pouches that do not stand up. To produce stand-up (doypack-style) pouches on a VFFS machine, specialised attachments are needed: a gusset insert creates a bottom gusset that when filled and sealed forms the stand-up base; or a block-bottom forming system creates a flat bottom for a stable standing bag. Specialist block-bottom bag machines (also called FFS block bottom machines) are purpose-built for high-quality standing bags for coffee, pet food, and premium snacks. A standard premade-pouch machine (pre-formed doypack filler) is an alternative approach for stand-up pouches without modifying a VFFS machine.
What film roll width do I need for my bag size?
For a pillow pouch VFFS machine, the required film roll width = (bag circumference / 2) + seal overlap allowance. Bag circumference = (bag width × 2) + (bag gusset depth × 2 if gusseted). For a 100mm wide flat pillow bag, film width = (100mm × 2) / 2 + 10mm overlap = 110mm. For a 100mm wide bag with 20mm side gussets, film width = ((100 + 40) × 2) / 2 + 10mm = 150mm. The machine manufacturer should confirm the exact film width calculation for their specific forming collar geometry.
