First-Aid plaster is an essential surgical dressing used for minor superficial injuries and abrasions. It is primarily composed of medical adhesive tape, an absorbent pad, and an isolation film. The medical adhesive tape used in band aids can be crafted from a variety of materials, including elastic cloth, polyethylene film, and non-woven fabric. These versatile band aids are ideal for treating small superficial wounds and dermal abrasions, fostering a conducive healing environment for minor skin injuries. Prior to applying a band aid, ensure the wound is thoroughly clean, and remember to replace the band aid regularly to prevent any risk of infection.
