For the purpose of this standard, the following definitions apply:
NOTE Other terms used in the manufacture of sacks are defined in EN 26590-1 for paper sacks and in EN 26590-2 for sacks made of thermoplastic flexible film. Most of these terms can also be applied to sacks made of jute/polyolefin fabric.
3.1
woven jute/polyolefin sack
a container made of woven jute/polyolefin fabric, closed at least at one end, possibly in combination with other flexible materials used for the liner, to provide the properties required for filling and the goods distribution chain
