Custom FIBC bags built around your product
A custom FIBC is specified by four choices: how you fill it (top), how you empty it (bottom), what it is made of (fabric, coating, liner) and how it is lifted (loops or belts). Mingzhe offers seven top styles and seven bottom styles and adjusts size, shape, thickness, material and colour to order.
Top options — choose by how you fill
| Top | Best for |
|---|---|
| Open top | Fastest loading for bulk products by shovel or grab. |
| Skirt (duffle) top | Full-width loading, then closed with a tie cord to cover the load. |
| Filling spout | Low-dust filling from a filling head or chute. |
| Conical top with spout | For products loaded through a high material cone. |
| Flip top (zip-lockable) | Easy access; the inner liner can be replaced easily. |
| Box top with filling spout | Keeps a square shoulder and protects the load after filling. |
| Spout with star-shaped closure | For products with high air content during filling. |
Bottom options — choose by how you empty
| Bottom | Best for |
|---|---|
| Flat bottom | Simple and stable; emptied by cutting or tipping. |
| Discharge spout | Controlled discharge for most free-flowing products. |
| Conical bottom with spout | For products that tend to bridge or form clumps. |
| Spout with star-shaped closure | Helps prevent bulging at the outlet during discharge. |
| Full open bottom | The bottom opens fully for fast emptying. |
| Siphon-plug discharge | Extra protection during transport and unloading. |
| Double discharge spouts | Two outlets for different unloading set-ups. |

Confirm specification & sample plan
We recommend a structure (top, bottom, loops, fabric) and agree the sample plan.
Sample production & approval
We make the sample; you check it and approve or ask for changes.

Inspection
Finished-product inspection before packing.
Shipment & after-sales follow-up
Shipment from Fujian, receipt confirmation and after-sales tracking.
Before step 1, it helps to read how to specify an FIBC bulk bag.
Coated, breathable or lined
We coat fabric in-house for waterproof and moisture-proof bags. For products that need to breathe we use uncoated or breathable fabric, and inner liners or aluminium-foil laminated bags are available on request.
Tell us what you pack — we will propose the bag
Send your product, fill weight and how you fill and empty the bag. We reply with a recommended structure and a quotation.
