A jute sack is a container made of jute, a plant fiber. Jute sacks are used to hold various materials, such as coffee beans, potatoes, and rice. They are also often used to hold livestock feed. Jute is a strong, durable fiber, making it an ideal material for sacks. Jute sacks are usually made from a single piece of fabric, cut to the desired size and shape. The edges of the sack are then sewn together, using a heavy-duty sewing machine. Jute sacks are typically brown in color, but can be dyed to any color desired.
