Jumbo bag (FIBC, Flexible Intermediate Bulk Container), also commonly known as a big bag, big jumbo bag, or bulk bag, is a practical container bag with a large capacity designed to safely hold and transport a wide range of products in granular, powdered, or piece forms. Crafted from durable woven polypropylene (PP) fabric—renowned for its strength and wear resistance—this packaging solution typically varies in size, load-bearing capacity, and design details to perfectly suit the specific properties of the products it carries, such as density, flowability, and storage requirements.
