Burlap

Burlap, also known as hessian, is a woven, rough cloth, made from jute, hemp, or other fiber.^[1]

Burlap is often sewn into large sacks for packing and shipping bulk foods such as dried beans and grains. After filling, the sack can be sewn closed and the stitching opened so the sack can be reused.
