Why Choosing the Right Filling and Discharge Options for FIBCs Matters

Flexible Intermediate Bulk Containers (FIBCs) offer incredible versatility for storing and transporting bulk materials. But to get the most out of your FIBCs, it’s not just about the size or weight capacity — it’s about how you fill and empty them. The filling and discharge design you select can have a big impact on your efficiency, product safety, and cost savings.

In this blog, we’ll explore the different filling and discharge options available for FIBCs, how they work, and how to choose the right ones for your operation.

Why Filling and Discharge Design Is Important

Efficient filling and discharge systems help:

• Speed up loading and unloading times

• Prevent product waste or spillage

• Improve worker safety

• Protect sensitive products from contamination

• Support automation in modern facilities

Choosing the wrong design can slow down production, increase labor costs, and create unnecessary waste.

Common FIBC Filling Options

1. Open Top (Duffle Top or Flat Top)

• Fully open design

• Ideal for products that don’t require dust control

• Common in construction, landscaping, and mining

2. Spout Top (Fill Spout)

• Narrow cylindrical spout at the top

• Helps control dust and product flow

• Ideal for powders, fine granules, or food-grade products

• Easily integrated into automated filling stations

3. Cone Top (Conical Top)

• Designed for materials that tend to pile unevenly

• Helps fill the bag fully and evenly

• Common for light or fluffy materials like flour or plastic pellets

Common FIBC Discharge Options

1. Plain/Flat Bottom

• Fully closed bottom

• Requires cutting or tipping the bag to empty

• Simple and low-cost for single-use bags

2. Discharge Spout (Spout Bottom)

• A controlled spout at the bottom

• Allows precise, dust-free emptying

• Common for powders, grains, and chemicals

3. Full Bottom Discharge (FBD)

• The entire bottom opens for fast discharge

• Ideal for sticky or non-free-flowing products

• Saves time when unloading heavy, dense materials

4. Conical Discharge

• Cone-shaped bottom helps funnel product out completely

• Reduces product hang-up

• Often used in food, pharma, and fine powders
