Sanitary pants OEM · Shanwei, Guangdong
We have run feminine hygiene lines in Shanwei since 1998. A sanitary pants OEM project here starts at 10,000 pieces per size, and the brief, the sample, the packaging artwork and the export documents stay with one team from first email to loading.
This page is for buyers who already know they want disposable period pants and now need to know what they can change, what it costs to change it, and what has to be decided before a sample is worth making.
Send the six fields below and we will come back with a specification sheet →

Start here
Most enquiries arrive with the phrase "OEM" attached to something that is private label. The three levels are not marketing tiers; they change what the factory has to buy, and that is what changes your minimum.
10,000 pcs per size
The product already exists. You choose the size range and the pack count, and the bag carries your artwork.
Threshold depends on the component
Structure, material, sizing or the printed backsheet changes. This is where a real OEM project begins.
Agreed per project
You bring a positioning and a performance target, and our engineering team builds the sample.
Practical note: A first order rarely starts at level 02. Buyers who test the market at level 01 usually come back for a second order with a changed core or a printed film, because by then they know which size sells. Starting at level 02 without sell-through data means paying for a change you have not yet validated.
Specification
A brief that answers these twelve fields can be quoted in one round. A brief that answers four of them produces a quotation that has to be rewritten twice, and a sample that misses on the detail you cared about most.
| Field | What we need from you | Our reference |
|---|---|---|
| Product type | Pull-up pants, or side-open pants | Both run on the same site |
| Size and waist | Which sizes, and the waist range per size | S to XL, 60–115 cm |
| Core length | Absorbent core length in mm | Set against the size, not fixed |
| Absorbency target | Day use, overnight, or a stated volume | Stated in ml on the spec sheet |
| Topsheet | Material and weight per m² | Nonwoven, weight stated |
| Backsheet | Film or cloth-like, printed or plain | Printed film from 50,000 pcs |
| Waist elastic | Full 360°, or partial with a gap | 360° is the standard build |
| Leg cuff | Raised cuff, double guard, or neither | Named on the spec sheet |
| Pack count | Pieces per bag or box | Set by your shelf plan |
| Pack format | Bag, box, or flow wrap | Bag compatibility checked first |
| Carton | Pieces per carton and carton mark | Mark follows your format |
| Barcode and language | GS1 number, and the market language | Printed from your artwork |
Absorbency is the field buyers leave vague most often. "Overnight" is a position, not a number. If the spec sheet says a volume, the sample can be measured against it, and a dispute later has something to stand on.
Cost
Buyers often ask for a price before the specification exists, then compare two quotes that were never for the same product. These four levers account for most of the gap between a low quote and a high one.
Topsheet and backsheet weight per square metre is the single largest swing. A lighter film lowers the price and changes how the pant feels and sounds. It is a real trade-off, not a trick, and it should be decided by the market you sell into rather than by the quote you want to see.
Fluff pulp alone is cheaper. Adding a superabsorbent layer raises cost and raises what the product can hold. Where the core sits, and how long it runs, matters as much as what it is made of, because a short core in a large size leaves the front and back exposed.
A plain film bag, a printed bag and a printed box are three different projects. Printed film needs cylinder time and a minimum run; a box needs a die and a packing line. Packaging is usually where a first order goes over budget, because it is decided last.
One size at one volume is the cheapest configuration. Four sizes at a quarter of that volume each is not, because setup runs four times. This is why a launch that covers every size at a small quantity costs more per piece than a launch that covers two.
| Cost block | What it contains | How it moves |
|---|---|---|
| Raw material | Topsheet, backsheet, pulp, superabsorbent, elastic, adhesive | Weight per m², and material choice |
| Converting | Line time, setup, waste at start-up | Batch size, and how many sizes |
| Packaging | Film or board, printing, cylinders, packing labour | Print run, and pack format |
| Freight and documents | Carton volume, loading, certificates, legalisation | Pack density, and destination |
Two quotations for "the same" sanitary pants OEM product are almost never for the same product. Before the numbers are compared, these five lines have to match, or the comparison is between two different projects.
Material weight. A quote built on a lighter film will look cheaper and will not feel the same. Ask for grams per square metre on both the topsheet and the backsheet, and put the two figures side by side.
Core specification. Pulp only, or pulp with a superabsorbent layer. Core length in millimetres, and where it sits in the pant. These three details decide what the product can hold.
What the packaging covers. A plain film bag with a sticker and a printed bag with a registered cylinder are not comparable, and neither is a quote that leaves the cylinder out and adds it later.
Carton density. Pieces per carton and carton dimensions decide how much freight you pay per piece. A pack that folds 10 mm thicker can add a container's worth of air across a large order, and that difference can exceed the gap in the unit price.
What is included at the minimum. Sample cost, plate or cylinder cost, and whether the minimum is per size or per order. A quote with a lower unit price and a per-size minimum can cost more at launch than a higher unit price with a combined threshold.
Ask each supplier to fill the same five lines on one page. The comparison that follows is usually shorter than the two quotations were.
Process
You send the twelve fields, or as many as you have. We come back with a specification sheet and the questions that remain open.
You confirm the sheet in writing. This document becomes the reference for the sample, the price and the inspection, so nothing depends on what was said in a call.
The plant builds a pre-production sample to the sheet. Existing stock samples can ship immediately; a changed construction needs its own build.
You check it, against the sheet rather than against appearance. Sign-off is the gate; production does not start on a verbal yes.
Artwork, barcode, carton mark and market language are proofed before printing. A pack proof that arrives after the film is printed is an expensive correction.
In-line checks during the run, a pre-shipment inspection at the agreed level, and a retained sample held against the batch. All three are written into the purchase order.
Packing list, invoice, certificates as required, and the loading sequence confirmed with your forwarder.
Where projects actually slip: not in production, but at step 2 and step 5. A spec sheet that was never signed leaves the sample open to argument; a pack proof that was never approved leaves the print run open to a reprint.
The brief lives in an email thread. Six messages in, two people remember two different waist ranges. A single specification sheet, signed by both sides, removes the argument before it starts and costs nothing but an hour.
Packaging is decided last. The pant is approved, the price is agreed, and the bag is chosen in the final week. That is when a printed film is discovered to need cylinder time and a minimum run the order does not support. Packaging should be decided at the same time as the product, because it carries its own minimum.
The size split is a guess. Four sizes at an equal quantity looks tidy and is usually wrong. If a buyer has no sell-through history, a first order weighted toward the two sizes that carry most of the market, with a smaller run of the extremes, is closer to what will actually sell.
The first order is treated as a test. A small first run is sensible, but it leaves no room for a reorder before the stock runs out, and a reorder placed after the line has moved on carries its own setup. A launch quantity is better planned as 6 to 8 weeks of sell-through plus a buffer, rather than the smallest quantity the factory will accept.
Sample review
A sample that looks right on a table can still fail in use. These six checks are the ones that decide whether a repeat order is easy or expensive.
Quality
Inspection that happens only at the end is a sorting operation, not a control. These four points catch different failures, and each one catches something the others cannot.
| Point | What it catches | When |
|---|---|---|
| Incoming material | A film or nonwoven lot that does not match the approved sample | On arrival, before the line runs |
| In-line leg seal | A seal drift that would leak, caught while the line is running | During production |
| Pre-shipment inspection | The overall batch, at the level agreed in the order | Before the container loads |
| Retained sample | Nothing at the time; it is what lets a later complaint be traced to a batch | Held from every run |
The factory operates under ISO 9001, ISO 14001 and ISO 45001, with hygiene production under GMP. Certificates are documents, and we share them as documents. We do not describe the site with approvals the file does not contain.
Packaging
A quotation that covers the pant and not the pack is incomplete. These five items are what a buyer receives, and each one has a decision attached.
Film bag, box, or flow wrap. Bag compatibility with the folded pant is checked before the format is confirmed, because a bag that is 5 mm too narrow distorts the fold and shows on the shelf.
A physical or digital proof of the finished artwork, including the print method, so colour and registration are agreed before the film is made.
Your GS1 number, placed at the size your retail channel requires. We print what you supply; the number itself is yours to register.
Pieces per carton, size, lot, and any handling marks your forwarder needs. This is decided with the carton dimensions, not after.
The language of the retail market, checked for the wording rules that apply there. This is the item most often left to the last week.
Claim control
This is the section buyers remember, because it is unusual. A supplier who will write anything is a supplier whose pack gets flagged, and a flagged listing costs more than the wording was worth.
| What a buyer asks for | What we print instead |
|---|---|
| A blanket no-leak promise | The structure that does the work: raised leg cuff, double guard, core length, waist range |
| A clinical-sounding grade claim | The material name and its weight, plus the statement that production runs under GMP |
| An antimicrobial claim | Left off, unless a test report names the standard and the result |
| A superiority claim | Numbers a buyer can check: since 1998, 35 lines, 260,000 m², the audit standards held |
| A skin-suitability claim | Only where a tested material sits behind it, with the test named on request |
None of this makes a pack weaker. A bag that says "overnight core, 360° elastic waist, 10 pieces" tells a shopper more than a promise does, and it survives a marketplace review without a rewrite.
Where it is made
Production runs in Shanwei, Guangdong, on 35 lines across 260,000 m². The site has made feminine hygiene products since 1998, which is long enough that most of the failure modes have already been met and written into the checks above.
The range runs from a 155 mm liner to a 420 mm overnight pad, and the pants cover S to XL at a 60–115 cm waist. Buyers who need both pads and pants in one programme do not have to split the order across two suppliers, which matters more than it sounds when the packaging has to look like one brand.
Power, water and material supply are the three things that stop a line. They are also the three things a buyer cannot see in a quotation, which is why the site is worth visiting before a large first order rather than after.
Questions
Private label uses a product that already exists and puts your brand on the bag. OEM changes the product itself: structure, materials, sizing, or the printed backsheet. Both run on the same lines. The difference is how much of the specification you control, and what the minimum becomes once you control it.
A starter private label run begins at 10,000 pieces per size. If the backsheet carries your logo printed into the film, the threshold is 50,000 pieces per size. A mixed L and XL order reaches that level at 100,000 pieces in total.
Send it, and we write a specification sheet from it: waist range, core length, topsheet, backsheet, elastic layout, pack count. You confirm the sheet in writing before sampling starts, so the comparison later is against numbers rather than memory.
They are scheduled separately, and both depend on which components change. A standard construction on existing film moves faster than a new printed backsheet, which needs cylinder time. We put the dates in the quotation and the purchase order instead of quoting one figure that suits every specification.
Yes, and most do. Each size carries its own minimum, so two sizes means two minimums. Mixing is normal at launch, because a buyer rarely knows the size split of a new market before the first sell-through.
On the bag by default. Printing into the backsheet film is a separate process with its own minimum of 50,000 pieces per size. It changes the film supply, so it is quoted as its own line rather than folded into the base price.
ISO 9001, ISO 14001 and ISO 45001, with hygiene production under GMP. Certificates are shared as documents on request. We do not claim product-level approvals that the file does not contain.
Describe what the product is and what it is made of: core length, waist range, pack count, material names. Wording that promises an outcome without a test behind it tends to fail marketplace review, and it is the first thing a competitor reports. We will tell you which lines we will not print.
Next
Product type, sizes and waist range, absorbency target, pack count, market, and the volume you are considering. That is enough to come back with a sheet, a price structure and the honest list of what still has to be decided.
