Adhesive bandage

life science Maturity 7-9 Next article →

An adhesive bandage is a small medical dressing. It is used to treat minor injuries. These injuries are not serious enough to need a full-size bandage. In British English, people call them a sticking plaster or a medical plaster.

You might also hear the name Elastoplast in the UK. In the US, Canada, Australia, and India, people often use the name Band-Aid. This is a genericized trademark. This means the brand name is used to describe all bandages of this type.

The primary job of a bandage is to protect a wound. It shields the area from dirt, damage, and bacteria. It also protects the scab from friction. This prevents the body's natural healing process from being disturbed.

Some dressings even have antiseptic properties. An additional function is to hold the two cut edges of the skin together. Doing this helps the healing process move faster.

The design of an adhesive bandage is very specific. It is a small, flexible sheet of material. One side of the sheet is sticky. In the middle, there is a smaller, non-sticky, absorbent pad. This pad is attached to the sticky side. To use it, you place the pad against the wound. Then, you smooth the overlapping edges of the sticky material onto the surrounding skin. Most bandages arrive in a sealed, sterile bag. They have a removable backing that covers the sticky side until you are ready to apply it.

Different materials are used to make these dressings. The adhesive is commonly an acrylate. This group includes methacrylates and epoxy diacrylates, which are also known as vinyl resins. The sheet itself can be a woven fabric or a plastic. Common plastics used include PVC, polyethylene, or polyurethane.

Some bandages are airtight. These are called occlusive dressings. Some people have allergies to these materials. These allergies often happen with latex or certain adhesives.

Bandages come in many different shapes and colors. Some are designed for children and feature cartoon characters. There is also a push for more variety in skin tones. This is because standard colors can be very conspicuous on darker skin.

Special bandages are also made for people who work with food. These are waterproof and have very strong adhesive. They are usually blue so they are easy to see if they fall into food. Some food-grade bandages even include a metal strip. This allows machines in food factories to detect them if they accidentally fall into a product.

There are several specialized variants of the adhesive bandage. One type is a transdermal patch. Instead of protecting a wound, these distribute medication through the skin. Another type is the butterfly closure, also called a butterfly stitch.

These are thin adhesive strips. They are used to close small wounds by being applied perpendicular to the laceration. This pulls the skin edges together. While they are not true sutures, they can sometimes be used instead of real stitches. Because they do not require a medical professional, they are common in first aid kits.

Many well-known brands produce these items for consumers. Notable brands include Band-Aid, Curad, Elastoplast, and Nexcare. These products remain essential tools for modern first aid. They connect simple material science with the biological need for wound protection.
