Absorbency: Sanitary pads are designed to quickly and effectively absorb menstrual fluid to prevent leaks and maintain dryness. They are typically made with highly absorbent materials like cotton, rayon, or a combination of both.

Shape and size: Sanitary pads come in various shapes and sizes to fit different body types and preferences. Some have wings to secure the pad in place, while others are longer or wider for increased coverage.

Breathability: To prevent discomfort and irritation, sanitary pads should be breathable. Many pads have perforations or micro-vents to allow for air flow.

Adhesives: Adhesives are used to attach the pad to underwear and prevent it from shifting. There are different types of adhesives, including hot melt, pressure sensitive, and heat seal.

Customization: Sanitary pad manufacturers can customize their products in a variety of ways, including adding fragrance, incorporating natural or organic materials, and designing the pad with unique patterns or prints. Additionally, some companies offer personalized sizing options or the ability to select from a range of absorbencies.
