What Exactly Is a Bulk Bag? (And Why Should You Care?)
Bulk bags—or FIBCs—are those big, flexible, and often polypropylene-made bags you see hauling thousands of kilograms of product.
They also go by:
- Flexible Intermediate Bulk Container (FIBC)
- Polypropylene bag
- Bulk sack
These bags are designed to hold and transport dry, flowable products like:
- Sand and gravel
- Grains and seeds
- Fertilizers
- Food ingredients
- Chemicals
You’ll find them with different build types:
- 1-ton and larger weight capacities
- Single or 4-lifting loops
- Coated or uncoated inner liners
- Baffle or ventilated designs
They’re the unsung heroes of safe handling, storing, and transporting and storing materials across industries.
Bulk Bag Benefits That Make Life Easier
Why do so many industries rely on bulk bags? Because they’re practical, cost-effective, and surprisingly smart! Their design allows for easy transportation and storage, minimizing waste and maximizing efficiency. Many companies also find ways to reuse bulk bags effectively, further enhancing their sustainability efforts. With their versatility, these bags can handle a range of materials, from grains to chemicals, making them an invaluable asset in various sectors.
Top perks include:
