The weight capacity of FIBC bags, also known as bulk bags or jumbo bags, varies greatly depending on several factors:
1. Size: Naturally, larger bags can hold more weight. Common sizes range from 500 kg (1,102 lbs) to 2,000 kg (4,409 lbs), with some reaching up to 4,000 kg (8,818 lbs) or even more for custom designs.
2. Material: The type of material used for the bag’s construction impacts its strength and weight capacity. Polypropylene (PP) woven fabric is the most common material, offering good strength and affordability. Other materials like coated PP or specialized fabrics for specific applications can offer higher capacities.
3. Design: The bag’s construction details, such as the number of loops, stitching type, and presence of additional reinforcements, influence its overall weight capacity. Safety factor also plays a role, with most bags designed to handle a weight significantly below their stated capacity to ensure safe handling.
4. Application: The intended use of the bag affects its weight capacity. Bags designed for lighter bulk materials like grains or feedstuffs might have lower capacities than those designed for heavier materials like sand or gravel.
Here’s a rough guideline for typical weight capacities based on size:
- 500-750 kg (1,102-1,653 lbs): Smaller bags suitable for smaller quantities or lighter materials.
- 1,000-1,500 kg (2,204-3,307 lbs): Popular size for various applications, offering a good balance of size and capacity.
- 1,500-2,000 kg (3,307-4,409 lbs): Larger bags for heavier materials or larger quantities.
- 2,000+ kg (4,409+ lbs): Custom-designed bags for specific heavy-duty applications.
