The fundamental difference: the form of your product.
Both machines wrap products in film — but their physical methods are opposite.
Vertical form-fill-seal machine (VFFS) Drop products from above into a vertically formed film pocket. Suitable for loose products: powders, granules, bulk snacks. Vertical product = gravity works for you.
Horizontal wrapping machine (flow pack) Delivers a fixed-shaped product on a horizontal conveyor belt, and a film wraps it as it moves—like caramel wrapping. The product does not fall, is not compressed, and does not shift from its position. Suitable for single shaped items: cookies, chocolate bars, bread, cakes, soap.
One of the most expensive questions when buying a machine is this simplest one: Is my product loose or shaped? Answer wrong, and an expensive machine will ruin your product every day.
Comparison table
| Criteria | Vertical Form Fill Seal | Flow pack (horizontal) |
|---|---|---|
| Product form | Loose: powder, granule, bulk | Individual & shaped: cookies, bars, bread |
| Normal speed | 40-120 bags/min | 100-300 packs/min |
| Fragile product protection | simple — product fall | High — no fall distance |
| Packaging format | Pillowcase/back seam 20 g-5 kg | Triple-sealed packaging by product size. |
| Filler | auger / cup / multihead | none — product has already been counted/shaped |
| Product count | by weight or volume | Follow the number (feeder or manual arrangement) |
| Powder compatibility | yes | not practical |
The speed figure is a typical industry range; the actual figure is determined by the product, film, and initial setup.
When VFFS wins
Your products are loose and sold by weight — 500 g of rice, 200 g of snacks, 50 g of spices, 1 kg of sugar. No other machine provides uniform bags at film costs as low as VFFS. For powders and granules, the filling configuration is described in Automatic powder packaging machine and Automatic granule packaging machine.
When the flow pack wins
Your product is in a fixed, fragile state. Three classic examples:
- Cookie — drop cookies from above into the bag (VFFS) and spend your weekends counting broken cookies. Flow pack sends cookies stacked on a belt, with film wrapping without any surprises. Specific example: cookie packaging machine.
- Bar chocolate and shaped snacks — The flow pack speed of 100–300 packs per minute easily outperforms VFFS for lightweight single-piece products.
- Bread and cake — no other machine is as gentle with the flow pack's delicate texture; the film seals without compressing the product.
Flow pack is also an option when packaging needs to closely follow the product's shape (less air, less film) — thin film packaging that adorns bakery shelves.
Common assumptions of both sides
“I can pack cookies in a VFFS machine with a soft chute.” Yes, with a drop adjuster and reduced speed — but you're paying for VFFS speed to get a lower output than a flow pack. At low volumes it's worth it; at high volumes it never is.
“The flow pack can fill powder using a funnel.” It technically exists, but a vertical seal moving with a dusty product is a source of pushback rates — a vertical powder machine solves this better and more cheaply.
“One flexible machine is better than two specialized machines.” For SMEs, yes—a semi-automatic all-purpose machine is often sufficient. For full-scale manufacturers, a dedicated machine running at full speed almost always outperforms an all-purpose machine running at half speed. Phased upgrade calculations included.

The answer in 3 questions
- Loose product (weighted by weight) or solid-shaped product (counted by piece)? — Loose → VFFS; shaped → flow pack.
- Does the product break when dropped from 30–50 cm? — Yes → flow pack.
- Target units/min above 150? — if the product is formed, use a flow pack; if loose, use a VFFS with a multihead scale or a multi-lane stick pack.
Frequently Asked Questions (FAQ)
Can one row have both machines?
J: It's possible and common — cookie production lines often have flow pack for primary packaging and VFFS for large family-size refill bags. Plan the layout and power requirements for both from the outset.
What is the actual speed of the flow pack?
J: 100–300 packs per minute for automatically sorted products; with manual sorting, speed is limited by human hands (typically 30–60 pieces). Infeed is often the most expensive part of a flow pack line—not the machine itself.
Are flow pack and VFFS films the same?
J: Most structures are the same (BOPP/PE, PET/PE), but flow packs often use reversible films (outer laminated sealant) for cold sealing at high speeds. The cost per package is low due to minimal film usage.
Which one is for the mixed nut snack?
J: Mixed nuts are a bulk product — VFFS with a multihead. See Snack food packaging machine and flow wrapping machine for those two classes.
