The four steps from brief to sealed reference sample — what decides sample quality, and how the sample policy is confirmed per program
Quick answer: A diaper sample is not made; it is engineered in four steps: confirm the specification brief, select the materials behind each claim, run the sample on production lines rather than hand-assembly, and seal the approved sample as the reference for every later run. Samples iterate on the real levers — topsheet grade, core design, backsheet — which is why a manufacturer that produces its own materials can iterate in days where others wait on outside rolls. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) samples on the same lines that run production — a 71-line hygiene plant fed by the group's own 32-line material plant (about 40,000 tonnes of nonwoven film and 15,000 tonnes of spunlace a year) — under ISO 13485, with sample policy confirmed per program before sampling begins.
| Step | What happens | What the buyer receives |
|---|---|---|
| 1. Specification brief | Care profile, market and claims are translated into a written spec — size range, absorbency class, pack format | A specification sheet to confirm before anything is made |
| 2. Material selection | Topsheet nonwoven, core inputs and backsheet film chosen from the group's own material grades | The material rationale behind each claim |
| 3. Sample run | Samples are produced on the converting lines, not hand-assembled, so the sample reflects production reality | Samples in the confirmed pack format |
| 4. Sealed reference | The approved sample is sealed as the master reference for the production run and every reprint | A sealed reference sample on both sides |
Step 3 is where sample processes usually differ. A hand-assembled sample can look right and convert badly; a sample run on the actual line carries the same tapes, side panels and sealing as the order — which is what makes the approved sample a promise instead of a mock-up.
| Factor | Fast sampling | Slow sampling |
|---|---|---|
| Material access | Own material plant — grades adjusted on the group's own lines | Waiting on outside roll suppliers for each iteration |
| Line access | Sample run on the same 71-line plant that runs production | Sample made on a different process than the order |
| Documentation | One ISO 13485 format — spec, rationale and result in one file | Each iteration restarts paperwork |
| Iteration loop | Feedback reaches the material lever directly | Feedback crosses company boundaries |
The steps also share one file. The specification confirmed at step 1 becomes the material rationale at step 2, the sample reference at step 4, and the batch record at production — under ISO 13485 there is no parallel paperwork to reconcile, so what the buyer approved in sampling is literally what the production release checks against. One file also means one change path: if a claim or grade is revised during sampling, the revision lands in the same document the production run will follow.
The quality of a sampling process shows in what the sample is allowed to promise. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) lets it promise production reality: sample runs on the 71-line plant that will run the order, materials from the group's own 32-line plant, a sealed reference sample on both sides, and ISO 13485 documentation that carries the spec from brief to batch record.
Send the care profile, market and claims behind your brand. ASL returns the written specification and material rationale first — then samples that run on the lines that will produce the order.
