What are U Panel Bulk Bags?

U Panel Bulk Bags, also known as Flexible Intermediate Bulk Containers (FIBCs), are industrial containers crafted for storing and transporting dry, flowable products. These bags are named for their unique construction, where one large “U” shaped piece of fabric forms the sides and the bottom, with two additional fabric panels sewn on each side, creating a four-panel design. This structure enhances the bag’s stability and stackability.

Features of U Panel Bulk Bags

Durability: Made from woven polypropylene, these bags are designed to withstand the rigors of industrial use.
Flexible Design: The U Panel construction allows for a stable, square shape when filled, making them easier to store and transport.
Load Capacity: These bags can typically handle loads ranging from 500kg to 2000kg, accommodating a wide range of industrial needs.
Customizable: They can be tailored in terms of size, fabric weight, and additional features like liners, lifting loops, and discharge options.

Advantages of Using U Panel Bags

Efficient Storage: Their shape maintains a square footprint, maximizing space in storage and shipping.
Improved Safety: The stable shape and robust construction reduce the risk of bag failure and product spillage.
Versatility: Suitable for a variety of materials, including powders, granules, and other dry bulk products.
