The Utility Bill and the Footprint Decide the Total Cost

What a turnkey sachet line actually includes

"Sachet line" is rarely one machine. A complete line is a vertical form-fill-seal or multi-lane unit, a product feeder, a printer for lot codes, a checkweigher, a metal detector, a cartoner or collar, and a case packer — plus the air, power, and water that run them. The quotation that prices only the former and sealer has priced a third of the cost. Read the scope before you read the speed.

Utilities: air, power, water

Compressed air is the silent cost. A multi-lane sachet line at 18,000/hr draws 600–900 NL/min at 6 bar; the compressor and its power are yours, not the vendor's. Sealing bars draw 8–15 kW; the printer and checkweigher add more. Water matters only if you clean in place, but most sachet lines are dry and clean by access, not CIP. Budget utilities as a line item, or the operating cost surprises you.

Footprint and layout

A turnkey line is 8–14 m long and needs 2.5–3 m of service aisle on each side. In a cramped hall, that footprint forces a single shift and caps volume; in Cairo we laid the line in an L to fit the hall, which added a transfer but avoided a second-shift lease. The footprint is a capacity decision, not a drawing detail. Confirm the layout against your actual wall positions before signing.

Integration cost often hidden

The gap between "machine delivered" and "line running" is integration: conveyors between stations, electrical panels, PLC handshake, and commissioning. Budget 15–30% of the machine price for this, or the line sits in crates. Require the vendor to quote integration as a line item with a commissioning date, not as "included" in a vague sentence.

Field case: sugar sachet line, Cairo, Egypt

The plant specified a 18,000 sachets/hr sugar line (4 g, 8-lane) for hotel and foodservice. The initial quotation covered only the former and sealer at a low price; utilities, cartoner, and integration were separate. We built the full scope: 8-lane VFFS, auger feeder with agitation, inkjet printer, checkweigher with reject confirmation, cartoner, and a 700 NL/min compressor.

Measured utilities were 15 kW electrical and 700 NL/min air — about 14% of operating cost. The L-layout fit the 11 m available hall without a second shift. Total installed cost ran 38% above the "machine only" quote, but the line started on the committed date and hit 18,000/hr in week two.

Where lines stall

1. Machine-only quotation. A third of the cost is feeder, checker, cartoner, integration. Read the scope.
2. Utilities unpriced. Air and power are 10–15% of OpEx. Budget them or the margin surprises you.
3. Footprint guessed. A line that does not fit runs one shift. Confirm layout against real walls.
4. Integration as "included". Vague integration means crates in the hall. Require itemised integration with a date.
5. No reject confirmation. A checkweigher that rejects but does not confirm lets bad sachets through. Require confirmed reject.

Meeting regional rules

European Union

CE marking; food contact under EU 10/2011. For sugar, average quantity rules apply. Lot-code printing supports traceability expected under food law.

United States

FDA 21 CFR 110 for food contact; NIST Handbook 133 for net quantity. No EU-style average-weight rule, but lot coding is expected.

Southeast Asia

Egypt bridges Africa and the Gulf; for broader SEA (Thailand, Vietnam, Indonesia), halal covers the Muslim market. High ambient heat raises compressor load — size the air supply for summer.

Middle East

Saudi SFDA and GCC anchor conformity; halal (SASO/GSO) mandatory. Summer heat pushes utilities up; budget compressor capacity for 45 °C ambient.

Specification & RFQ checklist

• Require a full-scope line quotation: former, feeder, printer, checkweigher, cartoner, integration.
• Demand utilities (kW and NL/min air) as a stated line item.
• Confirm the layout against your real hall dimensions before signing.
• Require integration itemised with a commissioning date.
• Specify confirmed reject on the checkweigher.
• Confirm CE / FDA / halal scope for your markets.

Questions buyers ask before signing

Why is the real cost 38% above the quote?

Because the quote covered the former and sealer only. Feeder, printer, checkweigher, cartoner, and integration are the rest. Always price the line, not the machine.

How much air and power do I need?

At 18,000 sach/h, about 700 NL/min air at 6 bar and 15 kW. That is ~14% of operating cost. Size the compressor for summer ambient or it stalls.

Will it fit my hall?

A line is 8–14 m long with service aisles. Confirm the layout against real walls; a bad fit caps you at one shift. In Cairo, an L-layout avoided a second-shift lease.

Is integration really 30%?

Between 15 and 30% of machine price, and it is the gap between crates and a running line. Require it itemised with a date, or it slips.
