A jute sack, or a burlap bag, is a bag made of a natural fiber. Jute sacks are often used to store and transport grains, such as rice, wheat, and corn. They can also be used to store other dry goods, such as coffee beans, flour, and sugar. Jute sacks are often used in agricultural settings, as they are strong and durable, yet lightweight. Jute is a sustainable and environmentally friendly material, making jute sacks a popular choice for many consumers.
