Feminine care products are thin, white and worn against sensitive skin. Every fiber decision is visible to the consumer, which makes this the least forgiving segment for pulp quality.
Application Overview
Sanitary pads and panty liners combine a soft topsheet, a thin absorbent core, and a barrier backsheet. Fluff pulp sits in the core, where it must provide fast absorption in a very small volume — often less than a third of the fiber used in a diaper core.
Because the core is thin, there is little room to compensate for a fiber that performs poorly. High fines content shows up immediately as slow absorption; poor brightness shows up as a grey cast through the topsheet; inconsistent fiber length shows up as a core that splits or shifts during converting.
This segment rewards specification discipline more than any other.

Typical Requirements and Our Approach
| Requirement | Typical Target | How We Meet It |
|---|---|---|
| Brightness | ≥ 86 ISO | Bleached softwood with a tight brightness window, batch-verified |
| Absorption speed | Under 2 s for a 5 ml dose | High freeness and low fines for immediate capillary uptake |
| Core uniformity | No visible density variation | Controlled fiber length distribution reduces forming drift |
| Softness | Smooth, no fiber protrusion | Hardwood or bamboo blend in the skin-contact layer |
| Whiteness stability | No yellowing in storage | Low extractables and controlled moisture at packing |
| Converting runnability | No core splitting or shift | Consistent sheet formation and controlled debonding |
Targets vary by format and market. Contact us for a specification matched to your product.
Detailed Description
Why thin formats are less forgiving
In a thick core, a small amount of poor-performing fiber is diluted by good fiber around it. In a thin core there is no dilution — the entire absorbent volume is only a few millimeters thick, so every property shows through. A pulp that performs acceptably in a diaper can fail outright in a liner.
Brightness is a consumer-visible property
In femcare, the core is often visible through a semi-translucent topsheet. Brightness variation between batches reads as inconsistent product quality, even when absorption is identical. Specify a brightness window, not just a minimum, and verify it per batch rather than per quarter.
Ask for the brightness range across the last ten batches, not the target value. The spread is what the consumer sees.
Softness without losing structure
Softness comes from shorter, finer fiber — hardwood or bamboo. But those fibers pack densely and reduce bulk, which in a thin core can slow absorption. The practical answer is a layered approach: soft fiber in the skin-contact layer, structural fiber in the absorbent layer.
