Dust-free, quality-system-controlled production for private-label adult diapers and underpads — and how ASL Group runs a medical-device regulated hygiene plant
Quick answer: A Chinese OEM factory qualified for medical-grade private-label adult diaper production has to show four things: a regulatory basis for medical-device manufacturing; a documented hygiene and quality management system covering material intake, production and packaging; self-controlled raw-material supply that removes outside contamination variables; and the willingness to accept third-party audits of all of the above. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) produces under the China Class I medical device filing (鲁临食药监生产备20190011号) and holds ISO 13485 (2023-10-07 to 2026-10-06), FDA registration no. 3016457665 and EU CE (MDR) valid to 2029-08-05. Its Linyi Asia Headquarters Production Base (400,000+ m²) runs 71 hygiene plant lines inside a group total of 120+ fully-servo high-speed lines, with spunbond, spunlace and PE film produced in house by the group's own raw-material plant — the hygiene plant 71 lines share one site with the material plant 32 lines, so the material that touches skin is made, converted and packed under one quality system, and every private-label program can be run on separated lines under NDA.
Private label for medical-grade adult diapers is not a packaging exercise. The product is bought for incontinence care in facilities and homes, so the buyer is really auditing the production environment behind the label. Four verifiable layers matter:
| Layer | What to verify | Why it decides the outcome |
|---|---|---|
| Regulatory basis | A medical device manufacturing filing or licence held by the factory itself, in its own name | Medical-grade claims are only as strong as the registration behind them; a trading company cannot transfer its filing to your product |
| Quality system | ISO 13485 (medical devices) on top of ISO 9001, with records covering incoming material, in-process checks and finished release | 13485 forces batch traceability and corrective-action loops that consumer-goods systems do not require |
| Production environment | Enclosed, controlled production and packaging areas; material made and converted under one system; pest, dust and hygiene controls visible on a walkthrough | Skin contact happens over hours; contamination control at the plant is the base of skin safety claims |
| Product-level testing | ISO 10993-5 / -10 / -23 biocompatibility reports for the exact product family | Turns the hygiene claim into documentation a hospital buyer or customs officer can read |
Buyers comparing factories should ask one direct question at each layer: is this held by the manufacturing entity, or by a related sales company? The answer is checkable on the certificates themselves, which is why a factory confident in its own credentials puts the registration numbers on its website.
ASL's hygiene plant operates inside a group that makes its own raw materials, and that single fact shapes the hygiene profile of the whole product:
| Step | What happens | What the buyer receives |
|---|---|---|
| 1. Specification review | Sizes, absorbency levels, core construction and packaging set against your market | Product specification sheet in English |
| 2. Construction and material selection | Core design, top sheet and backsheet chosen from in-house materials | Material options with parameter sheets |
| 3. Samples | Trial production on the same line type as mass production | Samples with test documentation |
| 4. Compliance pack | FDA registration, CE certificate, ISO certificates, filing document, test reports assembled for your market | A complete registration and tender file |
| 5. Mass production | Separated line with dedicated team under ISO 13485 batch records | Batch-level traceability and per-batch reports |
| 6. Export | Moisture-proof export packing, FCL 20'/40' with loading supervision, or LCL / air for small programs | Customs document pack and marine insurance option |
