Panty Liners from the Factory: Daily, Long & Organic Cotton

We manufacture panty liners and supply them direct from our own factory in Jiangmen, Guangdong — not through a trading desk. The standard range runs 150 mm, 155 mm and 180 mm, in the topsheet and pack your channel needs, supplied as bulk wholesale, your own private label, or under one of our own brands, including o2 for the eco line. Liners ship alongside our sanitary pad, tampon and adult incontinence programmes.

Samples come first: tell us the length, the topsheet and the pack, we send samples, you test them in your market, then you order.

The facts buyers check first

What We Make: 150 mm and 180 mm Liners, Round Head and Square Head

Three lengths carry the volume, and the differences that matter to a buyer are the ones a catalogue photograph does not show: the head shape, the width it produces, and the pack the width then fits.

Round head and square head: the 8 mm that changes your pack

The 150 mm liner runs on two cutting heads, and they do not produce the same product:

Eight millimetres of difference across the width decides the wrapper you need, the pieces that fit your carton, and how the liner sits in the panty: 62 mm is the narrower, more discreet build, 70 mm covers more of the gusset and reads as the more substantial product on shelf. Decide it before artwork — wrapper film is printed to the width it wraps, and changing head shape after the plates are cut is a new pack, not a tweak.

The 180 mm liner is built on a different topsheet station: a 35 g/m² web, 95 mm wide, cut to 186 mm — in PLA spunlace, hot-air, spunbond, pure cotton spunlace or organic cotton spunlace, plain or apertured. For a length above 180 mm, tell us the figure; 90 mm to 200 mm is the liner band, and we will confirm what the line can hold.

On length tolerance, GB/T 8939 allows a full-length deviation of ±4%, and we are comfortable recommending within ±5 mm on a finished liner. Write the tolerance you need into the specification; the retained sample, not the catalogue, is what order two gets checked against.

Which length goes where on the shelf

Length is a channel decision before it is a design decision.

Two facts sit behind that table. A liner is an entry product for a brand: bought more often than a pad, at a lower unit price, so a range that carries one usually wins the repeat purchase. And a liner is not a light pad — it is built to a different absorbency test, which is why a shopper who wants protection on a heavy day should be steered to a pad instead. That distinction is set out product by product in our panty liners vs pads guide; the liner specification and pack shots sit on the panty liner range page.

One boundary worth stating plainly: a liner is a light everyday product. If your channel needs a genuinely absorbent incontinence liner, that belongs to the adult range, quoted separately because the core, the test and the pack are all different — see our adult incontinence line.

Choosing the Topsheet at the Factory: Net, Cotton-Feel and Natural Fibre

The topsheet is the single largest lever on both the feel of the product and its cost, and the line item most often left vague on a purchase order. Three families matter.

Apertured PE film, sold as "net". A perforated film: fluid passes through the apertures and the film stays dry. The crisp, dry-feel option, and usually the cheapest way to build a liner.

Nonwoven, sold as "cotton-feel". Spunbond nonwoven is flat, strong and filament-based; hot-air nonwoven is loftier and softer against the skin, with a whitened ultra-soft grade and an apertured grade above it. None of these are cotton — they are how a liner is made to feel like it.

Composite. A cotton-net laminate, where a nonwoven face is combined with a film or a second layer to get softness and dry-through in one panty-liner topsheet.

The full option list splits into synthetics and natural fibres:

For the 180 mm liner, the topsheet is specified as a concrete combination rather than a general description — one of those five webs, plain or apertured. "180 mm, cotton-feel" does not tell a factory which web to load.

Where the cost difference actually sits

Two liners of the same length and the same pack can differ substantially in cost, and almost all of it comes from three places.

1. The fibre. A spunbond web and a certified organic cotton web are not in the same price band, and organic cotton carries documentation and handling on top of the material. The largest single gap.
2. Whether the web is apertured. Aperturing is a process step: you pay for the material and for putting holes in it, and the holes have to hold their size run after run.
3. Core weight and the release system. Core is dust-free paper at 50–80 g, and the higher end of that band costs more per liner. The back adhesive and its release paper are a small line item with a large effect on how the liner behaves in the panty.

Read the quotation as three lines — topsheet, core, back adhesive and release paper — and the price difference stops being mysterious. A quotation that will not name them cannot be compared with another.

Acquisition layer or chip: one station, one choice. On the 150 mm liner the acquisition layer and the functional chip share a station, so the line runs one or the other, never both. An acquisition layer spreads fluid across the core faster; a chip carries a functional claim — antibacterial, herbal cooling and similar. If your pack copy carries a functional claim, the chip is what supports it, and that decision consumes the station. The same logic sits behind individual SKUs such as the ultra-thin organic cotton biodegradable liner: the thinness comes from the core band and the topsheet together, not from the topsheet alone.

One structural note belongs with the topsheet decision: the absorbent layer in a liner is dust-free paper, nothing else on this line — which is explained below.

What We Cannot Make (and Why It Saves You Time)

Most supplier pages list what they can do. This section lists what we cannot: it is the fastest way for a buyer to know whether an enquiry is worth sending us, and a request describing a construction the line cannot run costs both sides a week.

Four constructions are outside what our liner lines produce:

• Fluff pulp and absorbent paper cores. A liner's absorbent layer is dust-free paper in the 50–80 g band. Build the core from fluff pulp or absorbent paper and it is not a liner any more — that is a light pad, and it should be quoted as one.
• Straight-strip wrapping — a liner wrapped in a straight tube rather than a folded wrap.
• Release film wrapping without release paper. The wrap we run carries a release paper layer; a film-only release system is a different build.
• Elasticised products. Anything relying on elastic, as a pad or panty does, is not something the liner line runs.

Why the core is dust-free paper, and why weight is capped

The absorbent layer must be dust-free paper, at 50–80 g. Dust-free paper is what delivers a thin liner that holds its shape; fluff pulp gives you a light pad instead, which is a different quotation.

Within that band, the weight cannot simply be pushed up. A liner is not cut inside its own edges the way a pad is, so the core runs to the edge of the product. A heavier dust-free paper is stiffer and more brittle at the trim, and it opens at the edge — a liner with an exposed core edge, and a visible defect on the very thing the shopper inspects. Ask for a heavier core and you are asking for a structural change, not a specification change.

What the line can do

The line runs at 600 pieces a minute, or 36,000 pieces an hour, and the automatic wrapping machine packs 3,600 packs an hour — in a plant of over 50,000 m² in phase one, with a Class 100,000 cleanroom and a Class 10,000 microbiology lab. Our manufacturing overview covers the site, the lines and how production is run: one factory in Jiangmen, exporting to 80+ countries.

The Standard Behind the Liner: What GB/T 8939 Measures

Two standards govern the product, and both are Chinese national standards — GB/T 8939-2018 for performance and GB 15979-2024 for hygiene, the latter effective from 1 July 2025. They are the standards this line is produced against. They are not international standards, and their scope is written for sanitary pads and panty liners sold in the domestic market — so if your market applies its own requirement, or your tender names another method, say so at the specification stage rather than at the port.

Here is what GB/T 8939 requires of a panty liner:

A liner and a pad are not the same purchase, even though they share one standard. Buyers often assume the two are tested identically because the standard number is the same. It is not: a sanitary pad is held to an absorbency ratio of ≥7 where a liner is held to ≥2, and the liner standard does not list the strip mass deviation or the absorption speed that the pad standard tests. Two consequences for a buyer:

• Absorbency claims do not travel between the two categories: a number on a pad pack and a number on a liner pack describe two different tests. A test report for a pad is not a test report for a liner — ask for the report on the construction you are buying, in the length you are buying.
• The standard sets the floor, not the marketing; if your pack copy implies protection, agree in writing which construction and which grade it is measured against.

Three hygiene grades, and which one your tender wants

Hygiene is graded separately from performance, and this is where tenders are won or lost — the limits differ by an order of magnitude between grades.

Read down the columns: bacterial count tightens tenfold from standard to disinfected, fungal count goes from a limit to zero tolerance, and the medical grade tightens absorbency and formaldehyde as well. The first two are Chinese national hygiene grades; the third, T/NAHIEM 37-2021, is a Chinese industry association standard for medical-grade hygiene products rather than a national one. So if a tender writes "medical grade" into its specification, the useful question is not what the pack says but which grade's limits are being tested against.

This table is the framework for that question, not a stock list. Which grades we run for your order depends on the market, the channel and the limit set your tender names — so tell us the limits you are being measured against and we will confirm in the quotation which grade we produce and test to, and which test report comes with the shipment. Settle that before you bid, because the grade is a line in your tender document, not a line on a pack.

Which grade you need follows the shelf, not the price list. Standard grade covers retail pharmacy and supermarket; disinfected grade is what a hospital or care purchaser typically writes into a tender; medical grade is specified where the product sits alongside clinical consumables and the tender names a limit set rather than a category word.

Biodegradable and Organic Cotton Liners

A conventional liner is not a small environmental problem; it is a durable plastic object in the shape of a liner. That comparison is the whole argument for the premium version:

Three components change, and each is a separate decision with its own cost: the topsheet to organic cotton, the individual wrap to a corn-starch film that breaks down rather than persisting, and the backsheet from PE film to a biodegradable film. A range can take one of those steps or all three — and which ones you take is what your pack claim is allowed to say. A corn-starch wrap does not make a polyethylene backsheet biodegradable, so a claim has to name the components it actually covers, which is why we would confirm the exact wording against the bill of materials for your build before the artwork is approved.

The organic cotton topsheet carries claims of its own, and these are the ones that matter to a sensitive-skin shopper: chlorine-free bleaching, no fragrance, no artificial dyes, 100% certified organic cotton. If your pack carries an organic claim, the documentation supporting it covers the cotton itself — a chain of custody for the fibre, not a supplier declaration. Ask for the certificate covering the grade you are buying, before the artwork is approved rather than after.

Two SKUs make the two positions concrete: the organic cotton biodegradable liner takes the organic-cotton route, and the starch and PLA biodegradable liner takes the plant-based-material route with a starch-based wrap. Our o2 brand is the range built around this positioning if you would rather distribute an established eco line than build one.

Which markets pay for it

The premium is real, so it should be aimed rather than spread across a range.

• Markets with packaging and waste obligations. Where packaging fees, plastic taxes or reduction targets fall on the party placing the goods on the market, the wrap and backsheet material decide what is owed and what can be printed on the pack. Your compliance team can cost that precisely — and the compliance argument often carries more weight internally than the consumer one.
• Retail chains with their own sustainability requirements. A listing requirement that names the wrap material or the fibre is a specification, not a preference, and it is usually the difference between being listed and not.
• Brands whose positioning is the product. An organic cotton liner is bought by a shopper who came looking for exactly that.

We will not tell you that every market rewards it. In a price-led market the same money usually buys more shelf presence through pack count than through a fibre upgrade, and a distributor who knows their shopper should say so. What we can do is tell you which components change, what each costs, and what claim each supports.

Packaging, Pack Counts and What Changes the MOQ

Packaging is a channel decision before it is a design decision, and for liners it is unusually simple at the primary pack and unusually consequential at the secondary one.

Cartons. 20 pieces to a box and 24 pieces to a box are both standard — a 150 mm organic cotton liner in a 20-piece box, a 15 cm liner in a 24-piece box, for example. Which count you take follows the shelf: the smaller box for pharmacy and trial, the larger for value-led supermarket and e-commerce multipacks.

Individual wraps. Two options: a plastic individual wrap, or a corn-starch biodegradable individual wrap. On a liner this is the component the shopper touches most, and on an eco-positioned range it is the first one worth changing.

Custom brand packaging is available across the range: you supply the design, or we design it if you have no artwork resource. Barcodes, languages, claims, pack architecture and the size-identification block belong in that brief — in a stockroom, picking the wrong length off a shelf is a recurring cost, and the fix sits on the pack.

MOQ is set by the printed pack and the plates behind it, not by a single flat number for the category. Printed film and cartons mean artwork, proofing and plates before the line runs, and the first order pays for them. Tell us the length, the topsheet, the pack count, the pack format and the market, and we will confirm the threshold for your specification in the quotation. Two things move it: whether you take an existing pack or bring your own artwork, and whether the plate or cylinder charge for a new printed film is absorbed by the first run or billed separately. Both are set out in the quote, so you can compare like with like.

Three routes are open, and they are not the same purchase:

• Bulk / stock packs under our own brands, for distributors who would rather skip label work — the range we run is set out on our brands page.
• Private label, where the pack is yours: our private label process covers artwork, pack architecture and label compliance.
• OEM/ODM, where the construction itself is developed to your specification rather than chosen from the list. That starts with the OEM/ODM process.

How to Order: Samples First

1. Send your specification — length, head shape, topsheet, pack count and format, quantity estimate, destination market.
2. We confirm and quote — including the specification, MOQ and lead time we can commit to, and the plate or cylinder charge if the pack is printed.
3. Sample — stock liner samples are free and you cover the courier. A custom construction is a development conversation rather than a stock sample: timing and any development cost are quoted with it.
4. Approve — you approve the physical liner and, for private label, the artwork. What you approve becomes the reference standard for the run, and we keep a retained sample of it.
5. Produce and ship — production, in-line checks, documents, shipment.

What to put in a sample request

Send all of these and you will normally get a usable sample and an accurate quotation in one round instead of three:

1. destination country and sales channel
2. length in millimetres, and whether your market calls it a day liner or a long liner
3. head shape, if the length is 150 mm — round or square
4. topsheet: net, cotton-feel, composite, or a named natural fibre
5. wings or no wings, if the length is 180 mm; and acquisition layer or functional chip, if the pack carries a claim
6. pack count and pack format, and whether the individual wrap is plastic or corn-starch
7. bulk, private label, or one of our brands, and artwork status if private label
8. hygiene grade your market or tender requires
9. estimated first order and annual volume
10. documents or test reports you need, and the incoterm and destination port

Leave items out and each becomes a question we have to ask before quoting — and that round trip costs you a week.
