Anion Chip (green,pink,or other choices)
SAP Absorbent Core
PE Breathable and Leak-proof back sheet
Hot Melt Adhesive
Release Paper
Individual Wrapper
All materials must undergo incoming inspection before entering the factory, including tests for basis weight, breathability, absorbency, cleanliness, and microbial control, to ensure that every batch of sanitary pad materials meets production standards.
For OEM factories focused on exports, establishing a stable international supply chain is particularly important; this not only ensures product consistency but also helps meet regulatory requirements in different countries.
2. Absorbent Core Formation
The absorbent core is the central component of sanitary pads and a key factor influencing absorbency.
Modern sanitary pad manufacturing typically employs a scientifically formulated blend of fluff pulp and SAP, using high-speed equipment to form a uniform absorbent layer.
There are significant differences in core structure requirements across different markets:
The European market prefers ultra-thin cores;
The Middle Eastern market prioritizes ultra-high absorbency;
The Southeast Asian market focuses more on value for money;
High-end brands are beginning to adopt multi-layer composite cores to improve instant absorption speed and back flow control.
OEM factories can typically adjust the SAP ratio, core thickness, and embossing patterns according to brand requirements to achieve differentiated customization.
3. Lamination and Forming
After the core is manufactured, the various layers of sanitary pad materials are precisely laminated using automated equipment.
This stage includes:
Laminating the flow-directing layer;
Laminating the top layer;
Laminating the backsheet;
Forming the wings;
Hot-press embossing;
Forming the leak-proof edges;
Adhesive strip application;
Release paper application.
The advanced automated production line ensures consistency in size, weight, and absorbency for every sanitary pad.

All of these features can be customized for OEM projects.
4. Packaging and Quality Inspection
After the molding process is complete, each sanitary pad proceeds to the individual packaging stage.
Once packaging is complete, the products must undergo several quality inspections, such as:
Absorption rate test;
Backflow test;
Leakage test;
Adhesive strength test;
Dimensional inspection;
Visual inspection;
Metal foreign object detection;
Microbiological testing.
Modern sanitary pad manufacturing plants typically use in-line vision inspection systems to monitor products in real time, reducing human error and improving product consistency.
The final products are only packed and shipped after passing sample inspections.
Sanitary Pads Materials: Why Do They Determine a Product’s Competitiveness?
For international brands, sanitary pad materials are not merely a component of the product’s structure; they directly impact the consumer experience, brand reputation, and regulatory compliance.
Currently, the international market is most focused on the following aspects.
Topsheet
Since it comes into direct contact with the skin, it should be soft, breathable, and hypoallergenic.
SAP
Determines the product’s absorbency.
High-quality SAP can quickly lock in moisture, reduce backflow, and enhance a long-lasting dry feeling.
Fluff Pulp
Provides basic absorbency.
Made from sustainably certified wood pulp, making it easier to gain recognition from international buyers.
Breathable PE Film
Good breathability helps reduce stuffiness and improves comfort.
Hot Melt Adhesive
Sanitary pads must have consistent adhesive strength without compromising the product’s breathability.
Wrapper Materials
More and more brands are adopting recyclable packaging materials to align with ESG and environmental trends.
Leading OEM manufacturers recommend combinations of sanitary pad materials that are better suited to local markets based on target market regulations, rather than simply offering standard products.
