The conventional basic form of bandage is composed of tape, water-absorbing layer, and isolation layer. According to different materials, it is divided into ordinary type, breathable type, water-blocking type, and elastic type. Band-aids should be trimmed neatly, the surface should be clean, free of stains and damage, and the adhesive tape should be evenly glued, without degumming, leaking, or seepage on the back. The water-absorbing layer of the band aid should be located in the middle of the tape, without obvious skew or dislocation, and its isolation layer should cross and completely cover the pasting surface of the band-aid, and there should be no tape or water-absorbing layer exposed. The water absorption rate of the water-absorbing layer of the wound sticker should not be less than 200%, the peel strength of the tape should not be less than 1.0N/cm, and the stickiness of the tape should not be greater than 2.5mm. The water vapor penetration of the breathable wound dressing tape should be no less than 500g/m² per 24h. When the water-blocking plaster tape is tested according to YY/T0471.3-2004, there should be no water seepage. The ratio of the recovery length to the fully extended length of elastic or elastic band-aid tape should not be greater than 80%. If the tradition band aid is sterile, it should be sterilized with ethylene oxide, and the residual amount of ethylene oxide should not exceed 10 μg/g. Basic band aid should be free of skin irritation and can be applied to small wounds.
