Two buyers price the same powder. One sees a pre-made pouch filler quoted 30 to 50 percent below a rollstock stick-pack line and assumes pouches will be cheaper to run.
At 150,000 units a month, that buyer is right. At 1.5 million a month, they are wrong, and the gap runs into six figures.
A per-1000-units range doesn’t tell you which way your own numbers fall, because the machine on the quote and the pack it produces point in opposite cost directions.
The lower-total-cost format depends on monthly volume and product rheology, not the headline machine price. Below a few hundred thousand units a month, capex and pre-made-pouch minimums dominate; above it, film-per-unit and labor-per-unit decide.
Pre-made pouch fillers are the cheaper machine to buy and the more expensive format to run. Industry estimates put an entry-level pouch filler near $80,000, running 30 to 50 percent below a servo-driven rollstock VFFS line that can exceed $150,000.
Vendor benchmarks tier pouch fillers by speed. Below $50,000 buys a semi-automatic machine at 10 to 40 pouches per minute; $50,000 to $150,000 reaches 15 to 70; above $150,000 runs 60 to 150-plus with zero to one operator.
Stick-pack machines don’t publish clean USD tiers. Vendors quote a vague band from several thousand to tens of thousands across 4-to-14-lane configurations, so treat any stick-pack sticker price as illustrative.
Read stick-pack capex per lane instead. A stick line forms the pack from film on the machine, then adds lanes to multiply output. A 6-lane stick line and a $150,000 VFFS line share the same cost physics: costlier to buy, cheaper per pack.
When you run the ROI math, amortize that capex over your real monthly volume, not the quote. At 500,000-plus units a month, a rollstock line pays back in 12 to 18 months against 24 to 36 for a pre-made pouch system. The cheaper machine quietly becomes the expensive choice once volume climbs.
Rollstock film for a stick pack runs $0.005 to $0.010 per unit; a pre-made flexible pouch runs $0.010 to $0.020 — two to four times more. Material is roughly 60 percent of total operating expense, so this line dominates the cost stack at volume.
Roll film saves 18 to 25 cents per thousand units, and aluminum laminate runs about $1.25 a pound on a roll versus $3.40 as a pre-made pouch. Pre-made formats also carry 12 to 15 percent trim waste against the near-98 percent utilization of a form-fill line.
A stick pack pushes the advantage further. Its narrow tube uses 10 to 40 percent less material than a four-sided sachet for the same fill, because it seals fewer edges.
The pouch wins the per-unit math at the other end of the curve. Custom-printed rollstock carries a minimum order of several hundred to about 1,000 kg per design, plus a printing plate for every SKU. Pre-made pouches skip the plate charge and let a brand run small batches across many SKUs.
For a snack brand with 20 SKUs and modest volumes, that flexibility usually keeps pre-made pouches at the lower total cost. Read your per-unit cost at the volume you actually run, not the volume the film salesman quotes.
Throughput sets labor cost per 1000 units, and the spread is wide. A rollstock VFFS line clears more than 200 pouches a minute; a pre-made pouch filler manages 35 to 90. A stick-pack machine runs up to 60 packs per minute per lane, so a six-lane unit lands near 300 a minute.
Labor scales the same way. One operator can tend three to four rollstock machines, while a pre-made pouch operation needs two to three staff, and each extra worker adds $18 to $22 an hour. Across millions of packs, that staffing gap becomes a per-unit line item.
Automation is where this compounds. Moving a manual line at five packs per minute to an automated filler delivered an 800 percent speed gain, cut three full-time staff to one part-time operator, and saved over $100,000 a year. The faster rollstock line reaches that gain on fewer operators.
A rollstock or stick line switches in 12 to 15 minutes against 30 to 45 for a pre-made pouch system, an 85 percent faster transition. Per event, rollstock clearly wins — but the calendar tells a different story the ROI spreadsheet usually misses.
Each daily changeover adds roughly $45,000 in yearly downtime on a form-fill-seal line. A short-run operation switching three or four times a day recovers that with a pouch system’s 10-to-20-minute transitions and no film rethreading.
Changeover is why SKU count is a second axis alongside volume. A high-volume line running one product favors rollstock on every cost driver.
The same volume split across a dozen rotated SKUs can flip the verdict back to pre-made pouches, even above the volume where film and labor say rollstock should win. Count your changeovers per day before you trust a volume-only answer.
The crossover sits between a few hundred thousand and low millions of units a month, and no single number holds, because the threshold moves with product rheology, SKU count, and label complexity. Two credible vendor models bracket it an order of magnitude apart, and that disagreement is the finding.
One model puts the rollstock crossover around 500,000 to 1,000,000 units a year: below it, pouches keep the lower cost; above it, rollstock wins.
A second places the flip at 15 to 20 million units a year. At 10 million units annually, pre-made pouches save about $250,000 over five years; at 50 million, the form-fill line saves $961,500.
The directional rule survives both. Free-flowing powders and high, steady volume push the crossover lower and favor a rollstock stick format. Liquids, viscous fills, low volume, and high SKU counts push it higher and favor pre-made pouches.
A reader can address either side with the matching machine class — a multi-lane stick-pack line for the high-volume powder case, a pre-made pouch filler for the low-volume, multi-SKU case. The choice is set by where your volume lands against the crossover, not by which quote is lower.
Run the numbers as total cost per 1000 units at your monthly volume. That conversion turns two conflicting vendor claims into one defensible decision.
Build the comparison as a worked cost-per-1000-units stack — amortized capex over your monthly volume, plus film per unit, plus labor per unit, plus annualized changeover. The winning format then becomes obvious, and the machine quote tells you almost nothing.
High, steady volume of a free-flowing powder makes a rollstock stick format cheaper once film and labor compound across millions of packs. Low volume, liquids, or a rotating set of SKUs keep pre-made pouches cheaper, because order minimums, slower throughput, and changeover frequency never let the capital pay back.
The cheaper machine rarely makes the cheaper pack, and the cheaper pack rarely comes from the cheaper machine. The only number worth trusting is the one you compute at your own volume.
