SAP Paper–Super Absorbent Core for Diapers&Sanitary Pads

SAP Composite Paper for Diaper and Sanitary Pad Absorbent Core

Our SAP composite paper integrates super absorbent polymer (SAP) into a paper-based structure, delivering high liquid retention, improved dryness, and stable core performance for modern hygiene products.

Typical Applications

Baby diaper absorbent core support
Adult incontinence core systems
Sanitary napkin high-absorbency layers
Medical hygiene absorbent products

How to Choose SAP Ratio?

Lower SAP (10–30%): better bulk and distribution
Medium SAP (30–50%): balanced absorption and thickness
High SAP (50–60%): maximum retention, ultra-thin designs

Our technical team can recommend the optimal configuration.

Sanitary Napkin Raw Materials SAP Paper Absorbtion Paper

SAP Paper for Sanitary Napkin Absorbent Paper Making Diaper Raw Materials

What Is SAP Composite Paper?

SAP composite paper is produced by embedding super absorbent polymer particles into airlaid or tissue paper.
It functions as an absorbent and retention layer inside diaper or sanitary napkin core systems.

This structure allows manufacturers to achieve:

Higher absorption capacity
Lower rewet performance
Thinner product designs

Key Performance Benefits

High Absorption & Retention

SAP rapidly absorbs liquid and locks it into gel form, reducing leakage risk.

Low Rewet Performance

Improves surface dryness and skin comfort.

Core Stability

Maintains structure after repeated wetting and compression.

Design Flexibility

SAP ratio and paper structure can be optimized for different diaper sizes and absorption targets.

FAQ – SAP Composite Paper

Q1: Is SAP composite paper the same as absorbent core?
No. It is a core material component, often combined with fluff pulp or ADL layers.

Q2: Can SAP composite paper replace fluff pulp?
In some designs, yes. It enables thinner cores, but final design depends on cost and performance targets.

Q3: Do you support OEM customization?
Yes. SAP ratio, GSM, width, and packaging are fully customizable.
