Ultra-Thin Absorbent Core Material

A SAP-based composite absorbent core sheet developed for modern hygiene product manufacturing. By combining SAP-based absorption technology with selected nonwoven, paper or distribution layers, the material helps manufacturers reduce product thickness while maintaining absorption, dryness and core stability.

Engineered for production lines that require consistent roll quality, customizable width, flexible GSM options and stable converting performance — suitable for both high-volume OEM supply and custom ODM project development.

Engineered for Performance

Six core performance dimensions designed to meet the demands of modern disposable hygiene product manufacturing.

01
Ultra-Thin Core Structure
Designed to support slim and lightweight hygiene product designs without compromising core functionality. Suitable for brands that need thinner sanitary pads, diapers or incontinence products.
02
Fast Liquid Acquisition
The engineered core structure helps guide liquid into the absorbent layer quickly, supporting a drier surface feel and reducing fluid concentration in one area.
03
Strong Absorption & Retention
SAP-based absorption helps lock liquid inside the core and improve retention performance for disposable hygiene products.
04
Low Rewet Performance
Can be customized to support low rewet requirements, helping improve dryness performance and wearing comfort in finished products.
05
Breathable & Flexible
Compared with bulky core structures, the ultra-thin composite design supports better flexibility and a more comfortable product profile for end users.
06
Customizable for OEM / ODM
Available in customized GSM, width, roll diameter, SAP ratio and layer structure according to product design and production line requirements.
