Introduction
As a leading integrated manufacturer and trader in the feminine hygiene industry, we master the end-to-end production of high-quality sanitary napkins. Our state-of-the-art automated facilities ensure precision, efficiency, and strict compliance with international hygiene standards. This page details our core manufacturing process, demonstrating our technical expertise and commitment to innovation.
The Fully Automated Production Flowchart
The modern sanitary napkin manufacturing process is a continuous, highly integrated operation. The following diagram illustrates the key stages from raw material to finished product:
Step-by-Step Process Breakdown
1. Raw Material Unwinding & Feeding
The production line begins with multiple large jumbo rolls, including:
• Top Sheet: Soft, hydrophilic non-woven fabric for quick liquid penetration.
• Transfer Layer: Efficient distribution layer.
• Fluff Pulp: The primary absorbent material.
• Super Absorbent Polymer (SAP): Advanced polymer granules for high-volume liquid locking.
• Back Sheet: Breathable PE film or composite material to prevent leakage.
• Release Paper: For adhesive backing.
2. Absorbent Core Forming
This is a critical stage. The fluff pulp is fiberized and then thoroughly mixed with SAP particles in a precise ratio. The blend is evenly air-laid onto a forming drum or conveyor to create a uniform, high-performance absorbent core. Advanced cores may use "composite" or "integrated" structures for superior acquisition and anti-leakage performance.
3. Multi-Layer Assembling
All layers are combined at high speed on a conveyor:
• The top sheet is placed first, often perforated or embossed.
• The transfer layer is added.
• The pre-formed absorbent core is positioned.
• The back sheet is laminated.
• Hot-melt adhesive is applied, and the release paper is attached.
4. Contour Cutting & Embossing
The continuous composite web is die-cut into individual pad shapes, including wings if applicable. Simultaneous embossing creates a surface pattern for aesthetics and enhances layer integrity.
5. Automatic Folding & Packaging
Each pad is folded (wings in) automatically. Robots then count and stack pads, placing them into flow-wrap packages (single or multipack). This occurs in a controlled, clean-room environment.
6. Sterilization & Final Packaging
Finished packages undergo a sterilization process, such as ethylene oxide treatment or E-beam irradiation, to ensure microbiological safety. They are then case-packed and palletized for shipment.
Our Technical Capabilities & Innovation
We focus on continuous improvement through:
• Material Innovation: Utilizing biodegradable, organic cotton, and breathable materials.
• Product Design: Developing ultra-thin, high-absorption, and comfort-focused pads.
