Understanding FIBC Bulk Bags

Definition and Versatility

FIBC bulk bags are large, durable containers designed for the transportation and storage of bulk materials, ranging from powders and granules to aggregates and chemicals.

Varied Applications

Their versatility makes them indispensable in industries such as agriculture, construction, and chemicals, streamlining the logistics of bulk material transportation.

Coated FIBC Bulk Bags – Shielding Your Cargo

Protective Coating Overview

Coated FIBC bulk bags come equipped with an additional protective layer, often made of materials like polyethylene, enhancing their resistance to external elements.

Benefits of Coating

Enhancing its defensive capabilities, the coating serves as an additional shield against moisture, UV radiation, and various environmental elements. This fortification is instrumental in maintaining the integrity of the materials housed within the bulk bags, ensuring their protection and longevity.

Uncoated FIBC Bulk Bags – Embracing Simplicity

Natural Fabric Characteristics

Uncoated FIBC bulk bag rely solely on the inherent characteristics of the fabric, typically made of polypropylene or polyethylene, without an additional protective layer.

Simplified Design

Their simplicity makes them an economical choice for materials that don’t require extra protection from external elements.

Comparing Coated and Uncoated FIBC Bulk Bag

Material Protection

Coated bags excel in safeguarding materials from moisture and UV exposure, while uncoated bags are suitable for dry materials that don’t require additional protection.

Cost Considerations

Coated FIBC bulk bags, with their extra protective layer, generally come at a slightly higher cost compared to the more straightforward design of uncoated bags.

Advantages of Coated FIBC Bulk Bags

Enhanced Durability

The additional coating increases the bag’s durability, making it suitable for materials that may be sensitive to environmental factors.

Versatility in Weather Conditions

Ideal for materials that will be transported or stored in varying weather conditions, the coating provides an extra shield against the elements.

Advantages of Uncoated FIBC Bulk Bags

Cost-Effective Solutions

Uncoated bags offer a budget-friendly alternative for materials that don’t require protection from moisture or UV exposure.

Lightweight Design

The absence of a protective coating makes uncoated bags lighter, potentially reducing shipping costs and environmental impact.

Customized Services by Zhaoyang

Tailoring to Your Material

Zhaoyang’s rich product line includes customized solutions for both coated and uncoated bulk bags, ensuring your specific material needs are met.

Advantages of Zhaoyang’s Customization

Tailored designs optimize functionality and cost-effectiveness, aligning with your unique material handling requirements.

Applications in Various Industries


Coated bags excel in safeguarding moisture-sensitive items like fertilizers or seeds during transportation. On the other hand, uncoated bags prove optimal for the bulk transport of dry grains or feeds, catering to diverse needs with precision.


In construction, where materials like sand and gravel may be exposed to the elements, coated bags offer optimal protection. Uncoated bags are suitable for transporting cement or dry aggregates.


For the chemical industry, where protection from moisture is crucial, coated bags are preferred. Uncoated bags may suffice for dry, non-sensitive materials.
