Sanitary Pad SAP Core Layer and Load Review for OEM Buyers
2026-07-31

SAP loading is part of the sanitary pad structure, not a slogan. Buyers should review how the absorbent core, transfer layer and topsheet work together in the approved sample. A good quotation becomes easier when the buyer states the target use and the expected core direction clearly.
Describe the Core Direction in Plain Terms
A buyer does not need to turn core review into a technical paper. It is enough to state whether the line needs stronger absorbent support, a lighter daily-use feel or a more balanced overnight structure. The factory can then connect that direction to the sample code and the expected pack route.
Compare the Core With the Surface
The surface and core should be judged together. A soft surface can still perform poorly if the core does not move liquid away smoothly. Buyers should ask for sample feedback on structure, feel and approved use scenario rather than separating one layer from the others.
Keep the Load and Size Link Clear
If the core load changes, the pad thickness, folded size and retail pack might also change. That means the buyer should keep the core reference with the size and pack record. When the pack count or length changes later, the file trail stays readable.
Ask for a Comparison Sample When Needed
If the buyer is choosing between two SAP directions, a comparison sample is more useful than a broad description. The buyer should note what changed, what stayed the same and which version fits the market better. That keeps the discussion practical and prevents vague follow-up questions.
