How the vertical process works

Each bag passes through the same sequence of stations; see how a VFFS machine works for the station-by-station cycle. The dosing unit releases a portion in time with film movement and cross-sealing; the timing depends on the selected machine.

  • Unwind the roll film.
  • Form the film around the tube and make the back seal.
  • Release the measured product through the tube.
  • Cross-seal, cut and discharge the bag.
  • Film unwinding and tension control, with a registration sensor when the film is printed
  • Forming shoulder and forming tube, which set the bag width
  • Longitudinal back seal made as a fin or lap seal
  • Film pulling by belts, with servo drives on selected configurations
  • Product discharge from the weigher or filler into the forming tube
  • Transverse jaws that seal the top of one bag and the bottom of the next, with a knife to separate them
  • Optional devices such as gas flushing, date coding, hole punching, gusseting or a degassing valve applicator
  • Discharge conveyor to checkweighing, metal detection or secondary packaging

Choose the dosing system for the product

The dosing unit usually decides whether a VFFS project works. It is chosen from the product's flow, piece size, stickiness and the fill tolerance you need, and it must be matched to the bagger's tube size, drop height and cycle timing.

For weighed pieces, the multihead weigher selection guide explains combination weighing, compares 10 and 14 heads, and shows how product release, cleaning and the VFFS filling window belong in the same configuration review.

For powder projects, the auger filler guide explains how screw tooling, powder flow and bulk-density changes affect dosing, and provides a sample-testing checklist before the head is matched to the bagger.

For liquids, gels and sauces in single-serve packs, compare the stick pack and sachet families to select the pump-dosed route.

Review the failure risk with the dosing choice
Product conditionDominant failure mode & prevention
Fragile chipsBreakage during transfer: review drop height and low-drop handling with the representative product.
Fine seasoning powderPowder in the seal: review dust extraction and the timing of filling and jaw closure.
Granules with changing bulk densityA fixed cup volume gives a changing fill weight: check representative batches before selecting volumetric dosing.

  • Pieces: multihead weigher.
  • Fine powders: auger filler.
  • Uniform free-flowing granules: volumetric cups; check bulk-density variation.
  • Multihead (combination) weigher: irregular pieces such as chips, nuts, candy, frozen food, kibble and coffee beans. Configurations for sticky dates and gummies use dimpled or coated contact surfaces, selected for the product.
  • Auger filler: fine or poorly flowing powders such as coffee powder, seasonings, baking mixes, soy products and detergent powder. Screw tooling and dust control depend on the powder.
  • Volumetric cup filler: free-flowing, uniform granules where volume tracks weight closely. It is simpler than a weigher but sensitive to changes in bulk density.

Bag styles and film

The bag style fixes the forming set and the jaw design. Film structure then decides the sealing temperature, pressure and dwell time the jaws must deliver, so send the film specification together with a reel sample.

For bags supplied ready-made, compare the premade pouch route below. A stand-up appearance alone does not identify how a bag is made.

  • Pillow bag: back seal plus top and bottom seals, the most common VFFS format
  • Gusseted bag: side gussets for more volume and a squarer shape
  • Quad-seal (stabilo) bag: four corner seals for coffee beans; confirm the finished base geometry with the bag drawing
  • Vacuum brick-pack routes for rice and grains require a separately confirmed vacuum and forming scope
  • Block-bottom and hole-punch bag options on the frozen prepared-dishes configuration
  • Film structure, sealing layer and any paper-based or recyclable laminate matched to the jaw temperature and dwell settings

Gas flushing, vacuum, washdown and difficult products

Nitrogen flushing is available on selected configurations for chips, coffee, nuts and pet food. The residual oxygen you achieve depends on the film barrier, bag volume, seal integrity and flushing arrangement, so it has to be measured on a trial rather than assumed.

Cleaning requirements must be reviewed for the quoted configuration. State whether you dry-clean, wipe or wash the equipment, identify the cleaning agents and describe the room temperature and moisture. Confirm product-contact materials, enclosure protection and access for cleaning in the quotation.

Some products need design choices beyond the dosing unit. State these at the start, because they change materials, extraction and cleaning access.

For storage conditions and the role of oxygen protection, read why nuts go bad and how nitrogen-flushed bags protect them.

For a flushing project, use the nitrogen flushing packaging setup guide to compare vertical bags with stick packs and premade pouches, define residual-oxygen sampling, and prepare the film, output and gas-use checklist.

  • Roasted coffee: degassing valve placement and aroma protection; see coffee packaging machines for bean, ground and instant formats
  • Fine powders: dust extraction near the jaws, since powder in the seal area causes leaking bags
  • Sticky or frozen products: anti-stick contact surfaces, condensation and low room temperatures
  • Detergents and other chemicals: corrosion-resistant construction on selected detergent configurations
  • Fragile snacks: drop height and product breakage between weigher and bag

What determines the configuration

Output depends on bag length, fill weight, how quickly the product settles, the film and the seal time. Use each configuration’s speed at its stated conditions; we confirm the output for your product and film in the quotation.

For motion selection, the continuous motion VFFS machines page shows how to tell a servo description from film that keeps moving during cross-sealing, and which product, film and output conditions to confirm.

  • Product name, physical form, bulk density and piece size
  • Target fill weights and the acceptable tolerance for each
  • Bag style, width and length for every format you plan to run
  • Film structure and reel specification
  • Required output in good bags per minute, and hours per day
  • Number of products and how often you change over
  • Gas flushing, vacuum, valve, coding or inspection requirements
  • Room conditions such as humidity, temperature, dust and washdown
  • Utilities available on site, including power, compressed air and nitrogen

Upstream and downstream equipment

A VFFS system usually includes a product elevator or feeder, the weigher or filler on a support platform, the bagger and a take-away conveyor. Checkweighers, metal detectors, cartoners and case packers may follow. Agree which of these units are in the quotation and who is responsible for each interface.

For single-serve portions in narrow packs, a multi-lane stick pack machine is usually a better fit than a vertical bagger. Retail pouches with zippers or spouts belong to the premade pouch route.

What LINEVO supplies as a VFFS manufacturer

LINEVO quotes VFFS equipment directly, with the dosing unit, bag tooling and auxiliary equipment specified for the project. Use the configuration pages to identify a starting route, then send the product, pack, film and required good output. The reply identifies the routes worth comparing or the details still needed.

Where material behavior is uncertain, agree whether a sample test is needed and which questions it should answer. Confirm sample quantity and shipping instructions before sending anything. Record the product, film, settings and observations with the result.

For a United States project or another export destination, our engineering team reviews plant voltage, phase and frequency, line interfaces and start-up needs. We define pre-shipment checks, documentation, installation and training arrangements, remote or on-site support, and spare parts in the project quotation.

Questions buyers ask about VFFS machines

Is a collar-type pouch packing machine the same as a VFFS machine?

Yes, for roll-film VFFS machines. Collar type refers to the forming collar, or shoulder, that turns flat film into a tube around the forming tube. Premade pouch configurations fill ready-made bags through a separate picking and opening process.

Can I buy a VFFS machine directly from LINEVO?

Yes. LINEVO is the manufacturer and quotes directly. Send the project brief; the team replies with questions and the routes worth comparing, and says whether a sample test is needed before the quotation.

Can one machine pack both powders and pieces?

Only if a second dosing unit is included or swapped in. An auger filler and a multihead weigher are different machines, so running both is a project decision rather than a setting.

How many bag widths can one machine make?

Each forming set makes one bag width, while bag length is adjusted within the machine's range. Extra widths need extra forming sets, which should be listed in the quotation.

Is nitrogen flushing standard?

Nitrogen flushing is an option on selected configurations, including the chips configuration linked below. Define the nitrogen supply, target residual oxygen and measurement method for the project.

Should I choose VFFS or premade pouches?

Choose VFFS when the proposed pack is to be formed from a film reel. Compare premade pouch filling when bags arrive ready-made, particularly for specified zipper or spout features. Compare the actual pack, format changes and quotation scope before deciding.
