A throwing line is a rope with little friction so that a somewhat thicker line can easily be drawn. A throwing line is intended to be able to pull rope to another point, they are used for rope access and recreational climbing activities such as canyoning. A sturdy and light throwline has only a light weight per meter and is still quite sturdy with a reasonable breaking strength. The throwing line is often made of polyethylene, the most commonly used plastic in the world. One of the important properties and advantages of polyethylene is that it is resistant to all kinds of chemicals, acids, alkalis and solvents. Various throwing bags, complete with the rope or not, are sold for taking along the throwing line.
