It is a thin, woven cloth tape with an adhesive on one side. The cloth is usually cotton or viscose-rayon, and the adhesive is usually latex-based or acrylic. Zinc oxide tape does not stretch – it is often described as ‘rigid’ tape – and is specifically formulated to stick to the skin. Basically, it is sticky tape for people.
Zinc oxide tape is widely used in sport and physiotherapy as a strapping tape – typically to strap up injured limbs and joints to limit or prevent movement. For instance, a sprained ankle can be immobilised by strapping it up with zinc oxide tape. It is also sometimes used preventatively to give extra support to vulnerable body parts, particularly wrists and fingers. Finally, some people stick it on areas prone to rubbing to protect or prevent blisters and calluses.
Correct preparation of the skin is essential for all adhesive strapping tapes. Tape will only stick reliably if the skin is entirely clean, dry and free from any oils, creams or lotions etc… Ideally, the area should be hair-free (or at least closely trimmed) because hair interferes with the bond and makes removal of the tape quite painful. Therefore, shave, thoroughly wash and dry the area before applying zinc oxide tape.
Zinc oxide tape can be cut with normal scissors, but it is often quicker and easier to tear the tape. To achieve this, just grip the tape at the edge with both hands and rip sharply as if you were tearing a piece of paper (but do it harder and faster.) Generally, it is best to unwind the tape from the roll as you apply it, a little at a time, and tear or cut off as you finish each strip.
Zinc oxide tape is strong and has no stretch, so it is important not to apply it very tightly or you risk cutting off blood circulation to the area. In many cases, all you need to do is lay it on the skin and press it down to activate the adhesive. For similar reasons, you should never build up a large amount of tape in one go nor repeatedly circle a limb with the same length of tape. Instead, apply it strip-by-strip: go around once, tear off, and then go around again etc…
Unfortunately, zinc oxide tape can cause irritation to sensitive or damaged skin. This can be true even of latex-free or supposedly ‘hypoallergenic’ tapes. Don’t apply tape to any area of damaged skin and even if the skin looks healthy don’t consistently wear tape for long periods of time. If you notice any irritation, stop using it.
