Structural Design Features:
1. Embossing: The backsheet surface often has embossed patterns. This enhances aesthetics and, more importantly, increases friction against underwear, helping secure the pad and prevent slipping.
2. Composite Layers: The backsheet may be laminated with a thin layer of spunbond non-woven or other material to enhance strength, texture, and anti-slip properties.
3. Leak Guards (Wing Backsheet): The backsheet material on the wings (flaps) also requires effective leak protection and secure adhesion.
