Traceability from Nonwoven Fabric and PE Film to Finished Diapers, Pull-Up Pants and Underpads

How one record chain follows material batches through production to a sealed carton — and what a buyer can request in order to test it

Quick Answer for Buyers

Quick answer: Traceability in adult-care manufacturing means a finished carton can be traced back to the specific material batches inside it, and forward to the shipment it left on. Two things make it real rather than aspirational: the key materials are produced inside the same group, and every production run is released under ISO 13485 batch records that name the material lots. Ask for four links — material batch, production batch, carton or shipping mark, and the release record — and then pick one delivered batch and ask them to walk it backwards. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) produces spunbond nonwoven, spunlace and PE and breathable film on its own 32-line raw-material plant feeding a 71-line hygiene plant on the 400,000+ m² Linyi Asia Headquarters Production Base, with non-woven fabric registered under FDA product code D369141.

The Four Links in the Chain

LinkWhat is recordedWhat a buyer can ask for
Material batchMaterial grade, supplier or internal production batch, arrival date and inspection resultMaterial identification and incoming inspection records for a nominated production run
Production batchLine, date, specification version and the material lots consumedBatch record naming the specification version in force
Product and cartonCarton printing, pack count and shipping marks tied to the production batchCarton and label examples matched to the batch
Release and shipmentISO 13485 (2023-10-07 to 2026-10-06) batch release and the loading record for the containerRelease documentation and the loading record for a nominated shipment

The test is not whether a factory has a traceability policy; it is whether a nominated batch can be walked both ways without gaps. That is why the practical audit question is: choose one carton you shipped me, and show me the material behind it.

Where a Chain Usually Breaks

Weak pointWhat it looks like in practiceHow it is closed
Material controlled on arrival, not on productionMaterial certificates exist but cannot be tied to a specific production runKey materials produced inside the group, so grade and history stay in one system
Specification version not named in the batch recordA material change cannot be matched to the orders it affectedBatch records that name the specification version in force
Cartons printed separately from the packCarton print cannot be tied back to the production batchExport carton labeling printed in the same flow as the pack
Loading not recordedDamage or shortfall claims cannot be matched to a containerLoading supervision with records for each shipment

Why In-House Material Is What Makes Traceability Work

Traceability Is Built, Not Claimed

A traceability claim is only worth what the first link supports. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) produces its own spunbond nonwoven, spunlace and PE and breathable film on 32 lines feeding a 71-line hygiene plant on the 400,000+ m² Linyi Asia Headquarters Production Base — 120+ fully-servo high-speed lines group-wide — with batch release under ISO 13485 (2023-10-07 to 2026-10-06), non-woven fabric covered by FDA product code D369141, and exports to 70+ countries and regions supported by EU CE (MDR) valid to 2029-08-05. Material batch, production batch, carton mark and loading record sit in the same system, which is what lets a buyer nominate one carton and ask for the material behind it.

Frequently Asked Questions

Can you trace a finished carton back to the nonwoven and film used to make it?
Yes. Material batch, production batch, carton or shipping mark and the ISO 13485 batch release record sit in one chain, and key materials are produced inside the group — spunbond nonwoven, spunlace and PE and breathable film from the group's own raw-material plant (32 lines). A nominated delivered batch can be walked backwards to the material that built it.
How does in-house material production affect traceability?
It removes the weakest link. When nonwoven, spunlace and film are made by the same group, their grade, production batch and history stay inside one quality system instead of being reconstructed from supplier certificates. Externally sourced materials such as SAP and pulp are inspected and status-controlled on arrival for the same reason.
Is the nonwoven material itself registered?
Yes — non-woven fabric is covered by FDA registration no. 3016457665 under product code D369141, alongside the finished-product codes. That makes the material side of a programme documentable, so a buyer can request material documentation and not only product documentation.
What documentation accompanies a batch?
The batch release record under ISO 13485 (2023-10-07 to 2026-10-06) naming the material lots and the specification version in force, carton and label examples matched to the batch, English test documentation where required (ISO 10993-5, -10 and -23 for skin-contact materials), and the loading record for the container.
How do we test traceability during an audit?
Nominate one delivered batch and ask for the four links in order: material batch, production batch, carton or shipping mark, and release record. A gap appears immediately if material certificates cannot be tied to a specific production run, which is the most common weakness in an otherwise well-presented factory.
Does producing in two countries complicate traceability?
No, because the record standard follows the product family. Whether an order is produced on the China or Malaysia side, the chain is material batch, production batch, carton mark and release record under the same ISO 13485 system, with FDA registration no. 3016457665 (China) and no. 3039282838 (Malaysia) identifying the producing entity.
