Choosing a Single-Sachet Wet Wipes Machine: What I Check Before I Quote
Earlier this year a converter in Saudi Arabia asked me a question I get almost every week:
“Send me your best price for a single-sachet wet wipes machine.”
I didn’t send a price. I sent back eleven questions.
Not because I was being difficult — because at that point, a price would have been meaningless. Two machines that both make “single-sachet wet wipes” can differ by 40% in landed cost and by a factor of three in cost per sachet once you run them for a year.
This article is the checklist I actually use. I’ve written it for the buyer, not for my own sales pitch. If you read it and decide to buy from someone else, that’s a fine outcome — you’ll at least buy the right machine.
First: what “single sachet” actually has to do
A single-sachet line is doing four jobs at once, and machines are usually good at two or three of them, not all four:
- Cutting and folding the nonwoven to a consistent size
- Dosing the lotion accurately onto each individual wipe
- Forming and four-side sealing the sachet
- Discharging in a way your downstream packing can handle
Most quotation sheets only tell you about job 3. The money is in jobs 2 and 4.
The six specifications that decide your real cost
- Rated speed vs. sustained speed
Every quotation shows a rated speed. Ask a different question:
“What is the speed you will guarantee during factory acceptance testing, running my material, for a continuous 4-hour run, and what waste rate do you accept at that speed?”
A machine rated at 600 sachets/min that runs stably at 450 with a 2% reject rate is a better machine than one rated at 800 that you can only run at 400.
Put the guaranteed sustained figure in the contract. If a supplier won’t write it down, that tells you what you need to know.
- Lotion dosing accuracy — the number that quietly eats your margin
This is the specification buyers underestimate most.
Lotion is a recurring cost; the machine is a one-time cost. If your target is 2.5 g per wipe and your dosing system varies by ±8% instead of ± e.g. 3%, you are overdosing on average to avoid dry sachets — and paying for that overdose on every single unit, forever.
Ask for:
- Dosing method (pump type, and whether it compensates for viscosity and temperature)
- Stated accuracy at your target weight, not at a convenient weight
- Whether accuracy holds at your lowest planned dose
At high volume, a few percent of lotion can outweigh the entire price difference between two machines within the first year.
- Changeover time between sachet sizes
Almost nobody puts this in a quotation, and almost everybody suffers from it.
If you plan to serve restaurants, hotels, and airlines, you will be running multiple sachet sizes and multiple print designs. Ask:
“How long does a full size changeover take, how many parts change, and do I need a technician or can a trained operator do it?”
A machine with a 20-minute tool-free changeover and one that needs 2 hours and a mechanic are different businesses, not different machines. If you’re doing short runs for many customers, changeover time may matter more than top speed.
- Nonwoven and film compatibility — with your material
Machines are commissioned with the supplier’s house material. Your spunlace may be a different GSM, a different composition, a different roll width, a different tension behaviour.
Send your actual material — nonwoven and packaging film — for the factory acceptance test. If your film is laminated aluminium foil for barrier reasons, say so early; sealing parameters and sealing jaw design differ from PE-based film.
For markets where the sachet carries Arabic and English printing on the same face, confirm the registration/eye-mark system handles your artwork before ordering film.
- Utilities and market conformity — the two cheapest mistakes to avoid
These cost nothing to check and a great deal to fix afterwards:
- Voltage and frequency. Saudi Arabia and several neighbouring markets run at a different frequency from mainland China. A motor and control package built for 50 Hz will not simply “work a bit slower” — it affects output, heating control, and warranty. Specify your exact supply on the purchase order, not in a chat message.
- Conformity documentation. For Saudi Arabia, imports fall under the SABER platform and SASO requirements, and your certificate of conformity has to be arranged before shipment arrives. Confirm in writing who is responsible for it — you, the supplier, or your agent. This is a very common cause of demurrage on first orders.
- Lotion formulation. If your formulation contains alcohol, confirm import treatment with your customs broker before you finalise the recipe. Rules vary and change; verify, don’t assume.
- Spare parts and the first twelve months
Ask for a written list of:
- Wear parts, with expected replacement interval and unit price
- Which parts are standard branded components and which are supplier-proprietary
- Lead time for a proprietary part, air freight, worst case
A machine where the critical parts are standard, catalogue-available components is worth a premium over one where every failure means a four-week wait for a custom part.
The eleven questions I asked
For anyone who wants the short version, this is what I actually sent:
- Target output per shift, and shifts per day
- Sachet dimensions and wipe fold pattern
- Nonwoven type, GSM, and roll width
- Lotion formulation, viscosity, and target dose per wipe
- Packaging film structure and print design
- Number of SKUs and expected changeovers per week
- Available factory floor space and ceiling height
- Power supply: voltage, phase, frequency
- Compressed air availability
- Who handles conformity documentation and customs clearance
- Who installs and trains, and what the operator’s technical level is
Nine of these eleven change the machine recommendation. Two of them change the price by more than the machine costs.
Why I no longer quote bare machines
I used to send equipment prices. Then I watched enough first-time buyers land a perfectly good machine and lose three months to something that was never on the quotation — a frequency mismatch, a conformity document nobody owned, an operator who had watched one demonstration.
The machine was never the hard part.
So a quotation from us now separates four things, priced individually so you can see and choose:
- Equipment — the machine, tested with your material
- Installation and commissioning — on your floor, with your utilities
- Operator training — until your team can run a changeover without us
- First-year spare parts kit — the wear parts you will actually need
You can buy only the first item. Some buyers with an experienced engineering team should. But you should be able to see all four line items before you decide.
