Six Tape Types

Beyond duct tape (Duck tape is a brand name), scotch tape, packing tape, and others are a few relatively unknown to many. Here are a few of the more interesting types of tape.

Speed tape is an aluminized adhesive tape used to do minor repairs on aircraft, and as a temporary repair material until a more permanent repair can be carried out. It has an appearance similar to duct tape, with which it is sometimes mistaken, but its adhesive is capable of sticking on an airplane fuselage or wing at high speeds. It is resistant to water, solvents, and flames, and will reflect heat and UV light. It is also able to expand and contract through a wide range of temperatures.

Bondage tape adheres to itself without using adhesives. Bondage tape is a 2-to-3-inch-wide (51 to 76mm) and 0.0051 inch-thick (0.13mm) strip of thin plastic material, usually latex. It is typically intended to be used for erotic bondage. Since it does not stick to the hair or skin, a person can be tightly bound or gagged without causing harm when the tape is removed

Elastic therapeutic tape, also known as K tape and kinesiology tape, is an elastic-cotton strip backed with acrylic adhesive. It is used for treating various physical disorders. It is claimed to be able to stretch up to 140% of its original length. As a result, if the tape is applied to a patient with a stretch greater than its normal length, it will recoil after being applied and therefore create a pulling force on the skin that it is being applied to. This elastic property allows much greater range of motion compared to traditional white athletic tape and can also be left on for long periods of time.

Gecko tape is being designed with directional adhesion properties, which is the ability to grip a load in one direction and to release its grip when the direction is reversed. The same structures on Scotch tape revealed that this material could support a shear stress of 36N/cm2, nearly four times higher than a gecko foot. This new material can adhere to a wider variety of materials, including glass and Teflon. When pulled parallel to a surface, the tape releases, not because the CNTs lose adhesion from the surface, but because they break, and the tape cannot be reused. It only works for small area (approximately 1 cm2). Researchers are currently working on a number of ways to strengthen the nanotubes.

Lingerie tape, also called cleavage tape or fashion tape is double-sided adhesive tape used to keep clothing in place.  It is used to secure the edges of a strapless dress or top to the cleavage or side of the breasts or on shoulders to secure bra straps from slipping, in order to keep the item of clothing in place. It may also be referred to as toupee tape or wig tape, a similar double-sided tape intended for a different function.

Road marking tape is reformed polymer tape that can be applied permanently or temporarily on pavement to create road surface markings.  It is heavy-grade material with reflective beads embedded in the plastic. It is commonly used to mark crosswalks, stop bars, and traffic guidance, such as turn lanes, HOV lanes, train crossings, pedestrian crossings, taxi lanes, bus lanes, etc.
