The documented export packing standard that carries adult diapers through weeks at sea — unit seal, carton, desiccant, container discipline — and why each layer is written, not improvised
Quick answer: A long sea passage exposes a diaper shipment to three enemies — humidity cycling inside the container, handling at transshipment points, and time. The standard that survives all three is written into a packaging specification per SKU, not chosen at the loading dock: sealed unit packs, a protective middle carton sized to stack, desiccant added as needed per route and season, and disciplined container loading. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) packs adult diapers to one export standard — inner PE film seal per unit pack, middle carton, desiccant as needed — specified per SKU, with supervised container loading, mixed or full 20'/40' loads to 70+ countries and regions, and ISO 13485 batch documentation behind every production run.
| Packing layer | What it does across a long sea passage | Where it is documented |
|---|---|---|
| Inner PE film seal | Seals each unit pack against humidity cycling and handling dust | Packaging specification per SKU |
| Middle carton | Stacking strength and count accuracy; protects unit packs through transshipment | Carton spec sheet with dimensions and grade |
| Desiccant as needed | Added per route and season where the passage profile requires it | Stated per order in the packing plan |
| Container discipline | Supervised loading, correct stacking, no mixed wet-dry cargo | Loading plan and supervised loading record |
None of these layers is optional, and none is a slogan. What protects the goods is that the standard is fixed in a document the buyer can audit — the packaging specification — so the carton that arrives is the carton that was specified, on every replenishment run.
| Confirmation | Why it matters at sea |
|---|---|
| Packing standard per SKU | The unit seal, carton grade and desiccant rule are fixed before production, not at loading |
| Carton stacking logic | Container loads are planned so cartons carry pallet-style stacking, which mixed-SKU loads make predictable |
| Loading supervision | A supervised loading record ties the sealed goods to the container condition at stuffing |
| Documentation set | Packing list matches the physical load — the first thing inspection at destination checks |
Routes differ, and the packing plan says so. A long passage with multiple transshipment points cycles humidity and handling more times than a direct sailing; a monsoon-season route condenses inside the container where a dry-season route does not. That is why desiccant is decided per route and season in the packing plan, and why the loading plan is written per destination — the standard is one discipline, the parameters are the passage's.
Goods survive a long passage because a standard was written before they were packed — not because the weather cooperated. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) fixes the standard per SKU: inner PE film seal, middle carton, desiccant as needed, supervised loading into 20'/40' containers planned per destination, and ISO 13485 batch records that keep the packing story and the production story in one file — proven across exports to 70+ countries and regions.
