Sanitary Pad Raw Material Composition and Properties

Sanitary pads are essential hygiene products used by millions of women worldwide. Understanding the raw materials used in their production helps in evaluating their quality, comfort, and environmental impact. This article explores the composition and properties of sanitary pad raw materials.

Core Components of Sanitary Pads

The primary materials used in sanitary pads include:

• Absorbent Core: Typically made of wood pulp or superabsorbent polymers (SAP) to retain fluids.
• Top Sheet: A non-woven or perforated film layer that allows liquid to pass through while keeping the surface dry.
• Back Sheet: A waterproof layer, usually made of polyethylene, to prevent leaks.
• Adhesive: Used to secure the pad to underwear.
• Release Paper: Protects the adhesive before use.

Properties of Sanitary Pad Materials

Absorbency

The absorbent core must quickly draw in and retain liquid to prevent leaks. SAPs are highly efficient, absorbing many times their weight in fluid.

Breathability

Modern pads use breathable back sheets to reduce moisture buildup and improve comfort.

Softness

The top sheet should be gentle on skin to prevent irritation, often achieved through fine fibers or textured surfaces.

Biodegradability

Eco-friendly pads use biodegradable materials like organic cotton, bamboo fiber, or plant-based SAP alternatives.

Emerging Trends in Materials

Recent innovations include:

• Antibacterial treatments to prevent odor
• Plant-based alternatives to synthetic materials
• Thinner designs with equal or better absorbency

Understanding these materials helps consumers make informed choices about comfort, performance, and environmental impact when selecting sanitary products.
