Everyday uses for bungee cord include the following:

securing objects or a load without having to tie knots

“no tie” shoelaces

external tie down cords on bags and packs

elastic drawstrings and cinch cords

camping and outdoor activities where a secure but shock absorbing anchor point is needed

replacement cord for backs and seating areas on bungee cord chairs

bounce-back netting for ball sports

crafting (especially small diameter bungee cord for bracelets as well as hair elastics and scrunchies)


There are the material of bungee cords specification:

Bungee cord is the common name for a type of cord with an internal core composed of one or more elastic strands and covered by a woven sheath. Other common names include “shock cord”, “stretch cord” and “elastic cord”. Bungee is sometimes spelled “bungie”.

Material used for the elastic inner core may be natural rubber, synthetic rubber, a blend of both or even other material. The inner core material will vary by manufacturer based on the intended use of the cord.

Quality bungee cord is manufactured to achieve a specific amount of elongation or “stretchiness”. The amount of elongation is expressed as a percentage of the unstretched length. Bungee cord with a 100% elongation rating can be stretched to double its original length. For example a 12 inch length can be stretched to 24 inches. By comparison, a 12 inch length of bungee cord with a 50% elongation rating can only be stretched to 18 inches.

The woven outer sheath may be made of cotton, nylon, polypropylene or other materials. The outer sheath protects the elastic core and facilitates uniform stretch along the entire length of the bungee cord.
