Plastic Bandage, also known as adhesive bandages or sticking plasters, are flexible strips of material used for covering and protecting small cuts, scrapes, or abrasions on the skin. Made of a porous backing material coated with an adhesive, adhesive bandages provide a protective barrier over wounds to prevent infection and allow for healing.

History and Development

The development of Plastic Bandages was an important advancement in first aid and wound care. Early versions in the late 19th century used tape and gauze secured with safety pins, which were uncomfortable and not very effective for smaller injuries. Johnson & Johnson debuted the first modern adhesive bandage under the brand name Band-Aid in 1920. This pioneered the use of plastic and medical-grade adhesive for a self-adherent strip that was kinder on skin while firmly holding its place. Since then, advances in materials and manufacturing have made adhesive bandages thinner, more breathable and compatible with skin.

Materials and Construction

Adhesive bandages are made of several key components that work together:

- Porous backing material: Usually a thin, flexible plastic like polyester that provides structural support and prevents water from entering the wound. Commonly clear films allow visibility.

- Adhesive layer: A skin-friendly adhesive like acrylate copolymer that secures the bandage cleanly to skin surfaces without dryness or irritation. Hypoallergenic adhesives avoid reactions.

- Absorbent pad: A thin pad of nonwoven material like cotton or rayon in the bandage center absorbs minor drainage from superficial wounds. Pad sizes vary based on bandage design.

- Release liner: A disposable strip of paper or plastic that protects the adhesive prior to application and peels away cleanly when needed. Liner-free bandages also exist.
