Bondage tape

Bondage tape is a 2-to-3-inch-wide (51 to 76 mm) and 0.0051 in-thick (0.13-millimetre) strip of thin plastic material (latex in most cases) that adheres only to itself, without any adhesive; it is typically intended to be used in erotic bondage. Since it does not stick to the hair or skin, a bottom can be tightly bound or gagged without causing harm when the tape is removed.

Some tape is thick enough that it can be unwound, unwrinkled and rewound for reuse, but usually it is simply and quickly removed by cutting it with blunt-tipped scissors.

If the tape is applied relatively flat on the body, the risk of losing circulation is minimal. Until the top is sufficiently practiced, the tape is easily twisted tight, becoming like plastic string and increasing the possibility of pinching and a loss of circulation.

This type of tape is also commonly used for stretching a body piercing.
