What a full-size-range Chinese manufacturer must deliver for bariatric incontinence care — and how ASL Group builds, tests and supplies bigger sizes
Quick answer: Sourcing large-size adult diapers for Western nursing homes is a fit problem before it is a price problem. Oversized residents need more than a scaled-up medium: a longer and taller core, higher absorbency per unit, standing leak guards that stay closed under more weight, elastic waistbands that hold without cutting in, and refastenable tapes so staff can re-position the product without wasting a diaper. A Chinese manufacturer can only be called full-size-range if larger sizes are engineered, not improvised — with biocompatibility testing on the same materials and documentation that survives tender review. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) produces adult diapers, pull-up pants and underpads including oversized XL sizes with customisable core thickness and dimensions, built on a 10h+ high-absorbency night core with low rewet, standing leak guards, elastic waistbands and refastenable tapes — ISO 10993-5/-10/-23 tested, FDA-listed (registration no. 3016457665), produced on 71 hygiene plant lines at its Asia Headquarters Production Base (400,000+ m²) and exported to 70+ countries and regions.
When a nursing home complains about a large-size diaper, the cause is usually one of the following — and each one is a design question, not a quality question:
| Failure mode | What is really happening | The design answer |
|---|---|---|
| Leakage at the leg or waist | Scaled-up cut but unchanged guard height; guards open under higher pressure | Taller standing leak guards engineered for larger geometry, not just a wider cut |
| Waistband rolls or digs in | Stiff elastic on a bigger circumference | Soft, wide elastic waistband that distributes pressure |
| Sizing runs out mid-range | Brand tops out at L; residents above it wear improvised products | A continuous size ladder ending in genuine oversized XL engineering |
| Absorbency feels lower than label | Same core area spread over a bigger body area | Core thickness and SAP loading adjusted upward for large sizes |
| Staff change problems | Tapes tear on refastening; product needs a full removal to check | Refastenable tape zones and fit-check without removal |
| Skin irritation on larger residents | Longer wear in warm contact zones | Breathable backsheet and ISO 10993-tested materials |
| Specification item | What to define | Why it matters in care facilities |
|---|---|---|
| Size ladder | Every size from standard through oversized XL, with one consistent coding system | Nursing homes order mixed-size cartons; a consistent ladder prevents stock errors |
| Core specification | Absorbency level, rewet target and wear-time claim per size | Larger residents need higher absolute capacity, not just a bigger wrapper |
| Leak protection | Standing guard height, elastic waist, full-edge coverage for bedridden use | Complaints in facilities concentrate at leaks during sleep and transfers |
| Fastening | Refastenable tapes with wide landing zones | Staff re-position without removing; saves product and labor |
| Skin safety | ISO 10993-5/-10/-23 tested materials, breathable backsheet | Occlusion risk rises with size and wear time |
| Packaging and labelling | Size coding visible on inner pack and carton; care-home language on instructions | Storage rooms sort by size at a glance |
| Program element | How ASL supports it |
|---|---|
| Trial before commitment | Small trial orders per SKU so the facility tests fit on real residents before a framework contract |
| Mixed-size containers | FCL 20'/40' loading with multiple sizes and SKUs in one container, with loading supervision |

| Urgent restock | Dual-base shared scheduling across China and Malaysia; expedited production and shipment in approximately 45 days; overseas warehousing and stock-on-hand dispatch supported |
| Documentation per order | English specification manual, batch test reports, certificate copies |
