Baby Diaper Raw Material

We provide one-stop sourcing solutions for all essential components used in baby diapers, ensuring quality consistency and stable supply for high-speed production lines.

What Is Diaper Material?

Diaper material refers to the combination of specialized raw materials used to manufacture disposable diapers.
Rather than a single component, diaper material is a system of materials, each performing a specific function such as liquid absorption, surface comfort, breathability, and fastening.

In industrial diaper production, diaper materials typically include absorbent materials, nonwoven fabrics, breathable films, and adhesive or fastening components. Selecting the right diaper raw materials directly affects diaper performance, comfort, and production efficiency.

Main Materials Used in Baby Diapers

Super Absorbent Polymer (SAP)

Super Absorbent Polymer (SAP) is the core absorbent material used in disposable diapers.
It is designed to rapidly absorb liquid and convert it into a gel, effectively locking moisture inside the absorbent core and preventing leakage or rewet.

In diaper manufacturing, SAP works together with fluff pulp to achieve high absorption capacity while maintaining a thin and lightweight diaper structure.
The performance of SAP directly affects diaper absorption efficiency, dryness, and overall user comfort.

Fluff Pulp

Fluff pulp is a cellulose-based absorbent material widely used in the diaper absorbent core.
Its primary function is to distribute liquid evenly and support the performance of Super Absorbent Polymer.

By working in combination with SAP, fluff pulp helps improve absorption speed, liquid distribution, and structural stability of the absorbent core.
Fluff pulp remains an essential raw material in disposable diaper production due to its reliability and compatibility with large-scale manufacturing processes.

Nonwoven Fabric

Nonwoven fabric is a key diaper material used in topsheets, acquisition layers, and inner linings.
It provides a soft surface that comes into direct contact with the skin while allowing liquid to pass through efficiently.

In diaper applications, nonwoven fabric contributes to comfort, breathability, and skin protection.
Different nonwoven structures and specifications are selected based on diaper design requirements and performance expectations.

Acquisition Distribution Layer (ADL)

The Acquisition Distribution Layer (ADL) is a functional layer placed between the topsheet and the absorbent core.
Its role is to quickly receive liquid and distribute it evenly across the absorbent core.

ADL is typically made from specialized nonwoven materials with high permeability and structural resilience.
By improving liquid acquisition and distribution, ADL helps enhance overall diaper absorption performance and reduce leakage risks.

Breathable PE Film

Breathable PE film is used as the backsheet material in disposable diapers.
It serves as a protective barrier that prevents liquid leakage while allowing moisture vapor to escape.

This balance between waterproof performance and breathability helps maintain a dry internal environment and improves wearing comfort.
Breathable PE film is an essential diaper material for modern disposable diaper designs focused on comfort and hygiene.

Diaper Tape & Frontal Tape

Diaper tape and frontal tape are fastening components that secure the diaper around the waist.
They enable repeated opening and closing, ensuring adjustable fit and ease of use.

In diaper manufacturing, these tapes must provide reliable adhesion, flexibility, and compatibility with automated production lines.
Fastening systems play an important role in diaper usability, fit stability, and overall product quality.

Elastic Materials for Diapers

Elastic materials are used in leg cuffs, waistbands, and other areas requiring flexibility and close fit.
They help prevent leakage while allowing natural movement and comfort during use.

In disposable diapers, elastic materials contribute to fit performance and wearing stability.
They are selected based on elasticity, durability, and compatibility with diaper structure and production processes.

Hot Melt Adhesive for Diapers

Hot melt adhesive is used during diaper production to bond different diaper materials together.
It plays a structural role by securing layers such as nonwoven fabrics, absorbent cores, elastic components, and PE films.

Although not visible in the finished product, hot melt adhesive is a critical material in ensuring diaper integrity and manufacturing efficiency.
Proper adhesive performance supports stable production and consistent diaper quality.

 

Nonwoven

1. Nonwoven Fabric (Top Sheet & Back Sheet)

Definition & Function

Nonwoven fabric is the main surface material of baby diapers. The top sheet contacts the baby’s skin and ensures comfort, while the back sheet protects against leakage. PP spunbond nonwoven is widely used for its softness, breathability, and cost efficiency.

Hydrophilic Nonwoven: Designed for the top sheet. lt quickly allows liquid topassthrough to the absorbent core, keeping the baby's skin dry.

Hydrophobic Nonwoven: Used for the back sheet or leakage quard areas. lt repels liquidto prevent leakage and provides a soft, dry outer layer.

Hot Melt Adhesive & SAP (Super Absorbent Polymer)

3. SAP and Fluff Pulp (Core Absorbent Layer)

Definition & Function

The absorbent core of baby diapers consists primarily of Super Absorbent Polymer (SAP) and fluff pulp. SAP rapidly absorbs and locks liquid within the core, while fluff pulp evenly distributes the liquid to maintain a dry surface. The synergy of these two materials directly determines the diaper’s absorbency, comfort, and rewet performance.
