The most common packaging decision - after “what machine type” - is VFFS (vertical form-fill-seal) versus pre-made pouch (doypack) machines. They solve the same problem differently, and the wrong choice costs either margin per pack or shelf presence. Here is the comparison with real numbers.
How They Work
VFFS machines form bags from a roll of laminated film, fill, and seal in one vertical motion. The machine makes the bag - you only buy film.
Pre-made pouch machines pick up ready-made pouches (stand-up, flat, spouted, zippered), open them, fill, and seal. The pouch is made elsewhere - you buy finished packaging.
Cost per Pack: The Decisive Math
Film for a VFFS-made pillow bag costs $0.02-0.08 per pack depending on size and laminate. A pre-made stand-up pouch costs $0.08-0.30 per pack. At 100,000 packs per month, that difference alone is $6,000-22,000 per month.
Machine price partially offsets this: VFFS + weigher combos run $15,000-40,000; doypack machines run $20,000-60,000 - a difference the film costs will erase within months at volume. Pre-made pouches only win the cost fight at low volumes or where the pouch format itself is required (spouted pouches, zipper pouches, premium stand-up).
Speed and Labor
| VFFS | Pre-made Pouch | |
|---|---|---|
| Typical speed | 40-120 bags/min | 20-60 pouches/min (rotary: up to 80) |
| Changeover | Quick (new former) | Longer (pouch magazine adjustments) |
| Staffing | 1 operator | 1-2 operators |
| Failure modes | Film breaks, sealing drift | Pouch jams, mis-opened pouches |
VFFS wins raw speed and changeover speed; doypack machines win on gentle product handling and pack appearance consistency.
Shelf Presentation
This is where pre-made pouches earn their premium: stand-up pouches with zippers, spouts, matte finishes and shaped silhouettes sell in retail environments that flat pillow bags cannot enter. If your distribution is retail shelves, weight the format against the cost. If your distribution is wholesale, food service or B2B sacks, VFFS pillow bags are the industry standard for good reason.
Product Fit
Choose VFFS when:
- Product is dry and free-flowing or dosable (snacks, coffee, grains, powders, pet food)
- Volume is high and margin per pack is thin
- Bags ship in cases, not on retail shelves
Choose pre-made pouch when:
- Format is part of the brand (stand-up, zipper, spout, shaped)
- Product is delicate (pre-made pouches fill with less drop impact)
- Volume justifies $0.08-0.30 per pack packaging
A Third Option: Hybrid
Many Chinese factories build VFFS machines that produce “looks-like-premade” bags: gusseted, quad-seal, and box-motion designs with premium printing. They cost more than plain VFFS and less than doypack lines, and for many food brands they hit the presentation/cost sweet spot.
How to Decide in One Week
- Calculate your monthly pack volume and multiply by the film vs pouch cost difference
- Check your channel: retail shelf means lean doypack or premium VFFS; wholesale/B2B means VFFS
- Ask 3 factories from the packing machine directory to quote both configurations for your product
- Request the video test on your actual product for both
