A gunny bag, also known as a jute bag or sack, is a type of bag traditionally made from jute fibers. However, with modern advancements, gunny bags are also manufactured using synthetic materials such as HDPE (High-Density Polyethylene) and HDPP (High-Density Polypropylene). These synthetic gunny bags are preferred in industries where moisture resistance and durability are essential, such as agriculture, construction, and industrial packaging. They provide reliable protection for goods during storage and transportation, ensuring product integrity and reducing the risk of damage or spoilage.
