What raw materials used in sanitary pads
Sanitary pads are essential products designed to provide comfort and protection during menstruation. The effectiveness of these pads depends significantly on the quality and types of raw materials used in their construction. Here’s a look at the primary materials commonly found in sanitary pads:
1. Super Absorbent Polymer (SAP)
SAP is a key component that gives sanitary pads their absorbency. This polymer can absorb many times its weight in liquid, keeping users dry and comfortable throughout the day. SAP ensures the pad remains thin while still being highly effective at absorbing moisture.
2. Non-Woven Fabric
This fabric is often used in the top and bottom layers of the pad. The top layer, which is in contact with the skin, is usually soft and breathable, preventing irritation. The non-woven fabric on the outer layer helps maintain the pad’s shape and ensures it stays comfortable and secure.
3. Absorbent Core (Wood Pulp)
Wood pulp or fluff pulp forms the absorbent core of many pads, providing the bulk of the pad’s absorbency. This material is lightweight and cost-effective, making it ideal for large-scale production.
4. Polyethylene (PE) Film
The PE film forms the waterproof backing layer of the pad, preventing leaks. This thin plastic layer helps ensure that moisture stays contained within the pad, protecting clothing and reducing the risk of leaks.
5. Adhesive
Adhesive strips are applied to the bottom of the pad to keep it securely in place. High-quality adhesives ensure the pad doesn’t shift, providing a stable fit even during active movement.
6. Release Paper
Release paper covers the adhesive until the pad is ready for use. It is removed before applying the pad, ensuring the adhesive remains effective and uncontaminated.
Each of these materials plays a crucial role in making sanitary pads both functional and comfortable. As consumer demand grows for eco-friendly options, more manufacturers are also experimenting with biodegradable and organic materials to make pads that are safer for the environment.
