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 lined cotton fabric.
lined cotton sack
a container made of cotton fabric, closed at least at one end, in combination with other flexible materials used for the liner, to provide the properties required for filling and the goods distribution chain
NOTE Hereafter where the word sack is used in the text of this European Standard, a sack made of lined cotton fabric is to be understood.
