The most fundamental choice in bag packaging is machine orientation: vertical (VFFS) or horizontal (HFFS, also called flow wrapper). The wrong choice wastes money on a machine that cannot run your product efficiently — or cannot run it at all.
The Core Difference
Vertical Form-Fill-Seal (VFFS): film is pulled vertically over a forming collar, shaped into a tube, sealed at the bottom, filled from above, then sealed and cut at the top. Gravity helps fill the product.
Horizontal Form-Fill-Seal (HFFS / Flow Wrapper): film is wrapped around the product as it moves horizontally on an infeed conveyor. The product is placed on the film, the film is folded over it, and the ends are sealed and cut.
The physical difference drives everything: VFFS drops product down; HFFS wraps product lying down.
Product Compatibility
| Product type | VFFS | HFFS (Flow Wrapper) |
|---|---|---|
| Powders (flour, spices, milk powder) | ✅ Excellent | ❌ Not suitable |
| Granules (sugar, rice, nuts) | ✅ Excellent | ❌ Not suitable |
| Free-flowing liquids (oil, sauce) | ✅ Good (with piston or pump filler) | ❌ Not suitable |
| Biscuits, crackers (flat, rigid) | ⚠️ Possible but fragile | ✅ Excellent |
| Chocolate bars, soap bars | ⚠️ Possible | ✅ Excellent |
| Baked goods (bread, cakes) | ❌ Will be crushed | ✅ Excellent |
| Solid items (hardware, toys) | ⚠️ With counting feeder | ✅ Excellent |
| Fresh produce (vegetables) | ⚠️ Possible | ✅ Good |
Rule of thumb: if your product flows (powder, granule, liquid), use VFFS. If your product is a solid object that sits flat, use HFFS.
Speed Comparison
| Machine type | Typical speed | Notes |
|---|---|---|
| VFFS (single lane) | 20–120 bags/min | Speed depends on fill time |
| VFFS (multi-lane sachet) | 30–120 sachets/min per lane | Total speed = lanes × per-lane speed |
| HFFS rotary | 40–300 packs/min | Faster because no gravity fill wait |
| HFFS box motion | 60–200 packs/min | Gentler product handling than rotary |
HFFS is generally faster for solid items because the wrapping motion is continuous — there is no “stop and fill” cycle. VFFS speed is limited by how long it takes to fill the bag.
Bag Styles
VFFS produces:
- Pillow bags (most common, lowest cost)
- Gusseted bags (stand-up with a bottom gusset)
- Stick packs and sachets (multi-lane)
- Bags with a bottom fold or top hang-hole
HFFS produces:
- Fin-seal packages (crimped ends, like a candy bar wrapper)
- Lap-seal packages (overlapping seal, uses less film)
- Modified atmosphere packs (with gas flush)
- Tray-ready wraps (shrink-tight around a tray)
Cost Comparison
| Machine | VFFS (auto) | HFFS (auto) |
|---|---|---|
| Entry level | $6,000–$12,000 | $8,000–$15,000 |
| Mid-range | $12,000–$25,000 | $15,000–$35,000 |
| High-end (servo, multi-head) | $25,000–$60,000 | $35,000–$80,000 |
VFFS machines are typically 15–30% cheaper than equivalent HFFS machines because the mechanical architecture is simpler. However, the total line cost may be similar when you add the multihead weigher (VFFS) or product infeed system (HFFS).
How to Decide
Ask these four questions in order:
- Does my product flow? (powder, granule, liquid) → VFFS
- Is my product a solid object? (bar, biscuit, hardware) → HFFS
- Is my product fragile? (chips, cookies, bread) → HFFS (gentler handling) or VFFS with specialized drop handling
- Do I need multi-lane small packs? (sachets, stick packs) → VFFS multi-lane
Still Not Sure?
Get a video test from both a VFFS and HFFS factory with your actual product and film. The cost of a wrong machine is far greater than the cost of a video test. Browse our packing machine directory — filter by VFFS or flow wrapper manufacturers and request tests in parallel.
