What is occlusive dressing made of?

Occlusive dressings are typically made from materials that create a barrier to moisture and air, promoting a moist healing environment. Common components include polyurethane films, hydrocolloids, or silicone materials, which are designed to be impermeable to bacteria and fluids while allowing for gas exchange. These dressings are often used for wounds such as burns, ulcers, and surgical sites to enhance healing and protect the area from external contaminants.
