When selecting a bulk bag (FIBC), you may come across the term perimeter band—a feature that enhances the bag’s durability and overall performance. A perimeter band is an extra strip of reinforced fabric sewn along the top edge of the bulk bag. Its primary function is to provide additional support, helping the bag maintain its shape and stability during filling, transport, and storage.


Benefits of a Perimeter Band:

  • Enhanced Bag Stability – Prevents the top of the bag from collapsing inward, making filling easier and more efficient.
  • Increased Strength – Reinforces the bag’s structure, reducing the risk of tearing or fabric distortion under heavy loads.
  • Improved Handling – Ensures the bag remains open and easier to manage during filling and discharge.
  • Consistent Shape for Stacking – Helps maintain a uniform shape, which improves stackability and storage efficiency.

Perimeter bands are commonly used in bulk bags designed for powders, grains, and other flowable materials, where maintaining an open-top structure is essential. While not all FIBCs require a perimeter band, industries that prioritize efficiency and durability often opt for this feature to improve handling and longevity.


If you're unsure whether a perimeter band is necessary for your application, consult with a bulk packaging expert to determine the best design for your operational needs.
