Jute is a long, soft, shiny vegetable fiber that can be spun into coarse, strong threads. It is produced primarily from plants in the genus Corchorus, which was once classified with the family Tiliaceae, more recently with Malvaceae, and is now included in the family Sparrmanniaceae. The primary source of the fiber is Corchorus olitorius, but it is considered inferior to Corchorus capsularis. Jute is one of the cheapest natural fibers and second only to cotton in the amount produced and variety of uses. Jute sacks are commonly used to pack food grains like wheat, rice, and pulses as they are strong and have a good capacity to hold these products. With the ever-increasing population, the demand for food grains has also increased, which has resulted in an increased demand for jute sacks. Jute sacks are also used to pack cement, fertilizers, and other such materials.
