A Revolutionary Industrial Package
Bulk bags, one of the most economical and efficient forms of industrial packaging, have revolutionized how goods are stored and shipped. Typically weighing less than 5 pounds – flexible intermediate bulk containers (FIBCs) are designed to shoulder substantial loads, easily supporting up to 5,000lbs. Their remarkable strength, durability, and adaptability solidify them as the go-to packaging choice for manufacturers across the globe.
Our inventory features an extensive variety of bag sizes, styles, and fabric types, specifically crafted to meet diverse operational and logistical requirements. Our standard 4 Loop bulk bags are engineered for toughness and safety.
As demand grows for practical and versatile bulk packaging, the significance of bulk containers only increases. We excel in providing super sacks that align with your specific material handling needs, taking into account factors like load capacity, safety, and operational efficiency.
Whether you need a custom-built or off-the-shelf bulk bag solution, Southern Packaging can provide an FIBC tailored to get the job done.
4 loop FIBCs are suitable for virtually any dry, flowable product. Their adaptable design and multiple fabric and construction options allow them to be configured for a broad range of materials across industrial, agricultural, food ingredient, and chemical applications.
Selecting the appropriate fabric type, liner configuration, and construction style ensures optimal performance based on the specific characteristics of the material being handled.
See Our 4 Loop Bag Styles
U Panel
Constructed with three main body components – one that runs the full length of the bag forming the bottom and two sides (the “U”) and two additional pieces of fabric sewn between the U on two sides (the “Panel”). The bag style is noted for it’s strength and durability.
Tubular/Circular
Consists of two main body components (Body tube + Base). The body tube is made with seamless tubular fabric that forms all sides of the bag allowing for stitching only for the top and base of the bag. This bag is the ideal option for fine materials due to the limited amount of seams.
Baffled
An internal component that can be added to a U-Panel, 4-Panel, or Circular style bag. Baffles allow a bag to maintain a square shape when filled. Baffled bags provide numerous functional benefits including optimized loading, stacking, and handling.
4-Panel
Constructed with five main body components (4 side Panels + Base). 4-Panel bags maintain a square shape better than Circular or U-Panel bags. With the addition of internal baffles, this bag style offers fantastic stability and stackability functionality.

Storage & Environmental Considerations
4 loop FIBCs can be stored indoors or outdoors depending on site conditions and the bag configuration selected. When storing bulk bags outdoors, exposure to moisture, UV light, and environmental elements should be carefully considered.
UV-stabilized fabrics are available to help protect bags during extended exposure. However, for long-term storage or moisture-sensitive materials, indoor storage is typically recommended to maintain both packaging integrity and product quality.
Stacking practices, pallet support, and proper load distribution should also be evaluated to ensure safe and stable storage conditions.
Use Case & Operational Versatility
The versatility of the standard 4 loop bulk bag makes it one of the most widely used FIBC styles in industrial packaging. With multiple top filling, discharge, lifting, and fabric options available, 4 loop FIBCs can be configured to support a wide variety of operational requirements.
From fine powders to coarse aggregates, selecting the correct bag style - U-Panel, Circular, 4-Panel, or Baffled helps optimize material containment, stacking performance, and handling efficiency.
