Sanitary Pad Structure Balance: Surface, Diffusion and Back Adhesive
2026-07-04
A sanitary pad is not a material-stacking contest. Surface, diffusion layer, absorbent core, backsheet and back adhesive must work together. If one part is improved while another part is ignored, the user experience can still be weak.

Surface Review
The surface should guide liquid away from the skin quickly and keep the wearing feel clean. Buyers should compare surface marks after use simulation and check whether the surface feels wet or sticky.
Diffusion and Core Logic
A core should spread liquid through the absorbent area instead of keeping pressure in one point. This helps the product feel more stable during sitting and walking.
Back Adhesive Control
Back adhesive should hold the pad in place but peel away cleanly from common underwear fabrics. The practical review is about coating uniformity, not only glue strength.
Buyer Review Table
| Review area | What to check | Buyer value |
|---|---|---|
| Surface | Dry touch and quick pass-through | Supports user comfort |
| Diffusion layer | Even spread inside the pad | Supports stable use |
| Core | Suitable thickness and absorption route | Matches price and positioning |
| Back adhesive | Hold and clean peel balance | Reduces daily-use complaints |

FAQ
Is a softer surface always better?
Not always. Buyers should check dry feel, liquid pass-through and surface residue together.
Should back adhesive be tested on one fabric only?
No. Cotton, modal and synthetic fabrics can behave differently, so several common fabrics should be reviewed.
Can Nafei support sanitary pad private label projects?
Yes. Buyers can discuss surface, size, core route, packaging count and carton marks with the OEM team.
