What Is ADL in Baby Diapers and Why Does It Matter?

ADL means acquisition and distribution layer. In general diaper construction, it refers to a layer positioned between the topsheet and the absorbent core, designed to help move and distribute liquid toward deeper layers. 

The presence, material, design, dimensions, and performance of an ADL can vary by product. Buyers should not assume any product claim or performance outcome without direct supplier confirmation.

1. Understand the General Role of ADL

ADL is commonly discussed as part of the diaper’s layered construction. Its general purpose is related to liquid acquisition and distribution within the product structure.

2. Request Product-Specific Confirmation

Ask the supplier whether the proposed product includes an ADL and which project-specific information can be confirmed.

3. Avoid Unverified Performance Claims

Do not assume absorbency, leakage protection, dryness, skin suitability, material composition, certifications, dimensions, or other claims based only on the term ADL.

4. Include ADL in Your Product Brief

If ADL information is relevant to your market, include it as a discussion point in your sourcing brief, sample-review criteria, and commercial evaluation process.

5. Request Samples for Internal Review

Use samples to support your internal commercial, market, regulatory, and quality evaluation. Define the criteria your organisation will use before making a purchasing decision.

6. Review Packaging and Labelling

Ensure all product and packaging information used in your market is directly confirmed and appropriate for destination-market requirements.

7. Compare Suppliers Consistently

Use the same product brief and evaluation criteria when comparing suppliers. This supports a more consistent commercial comparison.

8. Document Confirmed Details

Record only supplier-confirmed product details, packaging requirements, commercial terms, documents, and approval stages.
