It is extremely stretchy polyethylene tape which allows it to follow complex curves - like the perpendicular (no fillet) joint around the leading edge of the wing root  - although no tape can form to every curve. This tape utilizes UV protection so that is lasts longer in the sun than other products. That is very important for gliders that remain rigged for long periods of time - especially if they sit in the sun all the time. The tape is designed to stay in place and not split even when you take off from an airfield with high temperatures, fly at high altitude in low temperature environments and land back in high temperatures.
