How does Self-adhesive bandage work?

Self-adhesive bandages, also known as cohesive bandages or self-adherent wraps, are versatile and flexible medical products used to secure and protect injuries or provide support to joints and muscles. These bandages adhere to themselves without the need for additional fasteners or adhesives, making them easy to use and adjust.

The working mechanism of a self-adhesive bandage involves a combination of elastic properties and a special cohesive material coating. Here's how it works:

    Cohesive Material: Self-adhesive bandages are made of a non-woven fabric or elastic material that has a thin layer of cohesive material applied to one side. The cohesive material is usually latex, latex-free, or silicone-based. It has a tacky texture that allows it to stick to itself but not to the skin, hair, or clothing.

    Wrapping Technique: To apply a self-adhesive bandage, you start by holding the end of the bandage against the skin or the starting point of the wrap. Then, you gently stretch the bandage while wrapping it around the injured area or joint. The tension applied during wrapping helps provide support and compression.

    Self-Adhesion: As you continue wrapping, the cohesive material on the bandage sticks to itself due to its sticky nature. It creates a secure and snug fit without the need for any additional fasteners like clips or pins. The self-adhesive property ensures that the bandage stays in place during movement or activity.

    Controlled Compression: The elastic nature of the bandage allows it to provide compression to the wrapped area. Compression helps reduce swelling, stabilize injured joints, and promote healing. The self-adhesive bandage can be wrapped more tightly or less tightly depending on the desired level of compression.

    Breathability and Flexibility: Self-adhesive bandages are designed to be breathable, allowing air to reach the skin and prevent moisture buildup. This feature helps maintain a healthy environment for the wound or injured area. The bandage is also flexible, allowing for a full range of motion without restricting movement.

    Easy Removal: When it's time to remove the bandage, you can simply unwind it by pulling on the edge. The cohesive material adheres only to itself and not to the skin, making it painless and easy to remove without leaving any residue.


Self-adhesive bandages are commonly used in first aid, sports injuries, sprains, strains, and other minor injuries. However, for more severe or complicated injuries, it's important to seek professional medical advice.
