Compound Fertilizer FIBC Bag with Lifting Belts and Loops for Full-Bag Lifting and Handling

Product Introduction

This Compound Fertilizer FIBC uses a combined structure of four main lifting belts and four independent lifting loops for full-bag lifting, forklift transfer, warehouse handling and logistics after fertilizer filling.

The bag size is 105 × 105 × 125cm. It uses 180gsm white coated fabric with minimum warp and weft strength of ≥1500N.

Four 55 × 100cm internal baffles, a top filling structure and a bottom discharge structure are also integrated into the bag.

The main design focus is not one isolated specification, but how the lifting structure, filled-bag shape, filling and discharge configuration work together during full-bag handling.

Problem

After compound fertilizer is filled, the FIBC changes from a lightweight empty bag into a filled package that must be lifted and transferred.

Many purchasing projects confirm bag dimensions and fabric specifications but do not check how forklift forks will enter, where lifting equipment will connect or whether sufficient operating space is available around the filling station.

If the lifting belt length, lifting-loop position or handling structure does not match the actual equipment, the bag may still be difficult to move even if filling itself is completed successfully.

Granular fertilizer can also expand laterally after filling, increasing the space required for forklift operation and warehouse arrangement.

Solution

1 Lifting Belt and Loop Combination

The FIBC uses four 7 × 190cm main lifting belts and four 7 × 88cm independent lifting loops.

The main lifting belts are positioned along the bag body and connected using double-needle chain stitching. The lifting loops use reinforced overlapping construction with W-shaped and multiple reverse-stitch lines.

The main belts provide the primary structural connection for lifting, while the additional loops provide dedicated connection points for handling operations.

This structure is particularly relevant for fertilizer packaging processes involving filling, lifting, forklift transfer and warehouse storage.

2 Internal Baffles for Filled-Bag Shape Control

The bag includes four internal baffles measuring 55 × 100cm, each with 10 × 30cm oval openings.

After compound fertilizer enters the FIBC, the granules apply lateral pressure to the side walls.

The baffles provide additional restraint against excessive lateral expansion, while the oval openings allow material to continue flowing between different internal areas.

The baffles and lifting system therefore perform different functions: baffles control filled-bag shape, while lifting belts and loops support lifting and transfer.

3 180gsm Coated Body Structure

The main bag body uses 180gsm white coated fabric with minimum warp and weft fabric strength of ≥1500N.

For compound fertilizer FIBCs, 180gsm should not be evaluated as an isolated number.

Fabric weight should be considered together with mechanical strength, lifting configuration and overall bag construction.

The coated structure reduces direct contact between fertilizer granules and the external environment and is suitable for industrial fertilizer packaging, storage and logistics.

Without dedicated waterproof or moisture-barrier testing, it should not be described as completely waterproof.

Specification

Application

This FIBC is mainly designed for full-bag lifting and handling of granular compound fertilizer after filling.

It is suitable for projects involving forklift transfer, centralized warehouse storage or subsequent logistics transportation.

Depending on actual material conditions, a similar configuration can also be evaluated for NPK compound fertilizer, granular urea, granular ammonium sulfate and other fertilizer granules with similar packaging behavior.

For projects using fixed filling equipment, the φ45 × 50cm top filling structure can serve as an interface reference. After transportation or storage, the φ45 × 50cm bottom discharge structure provides a defined path for downstream unloading.

The product is therefore particularly relevant to fertilizer processes covering filling, full-bag lifting, forklift transfer, storage and downstream discharge.

How to Choose

1. Confirm How the Filled Bag Will Be Handled

Do not start only with bag dimensions.

First confirm whether the site uses forklifts, lifting devices or another handling system, and check fork dimensions, lifting height and available operating space.

The current structure uses 7 × 190cm main lifting belts and 7 × 88cm loops, but actual compatibility depends on the customer's handling method.

2. Determine Whether Both Belts and Loops Are Needed

For simple short-distance handling, a standard lifting configuration may already be sufficient.

If filled bags require repeated lifting and transfer or the project needs clearer connection points for lifting equipment, the combined belt-and-loop structure can be considered.

The goal is equipment compatibility rather than simply adding more lifting components.

3. Decide Whether Internal Baffles Are Required

If filled-bag shape is not important, a conventional structure may be adequate.

If warehouse space is fixed, multiple filled bags need more regular positioning, or lateral expansion affects forklift operation, internal baffles become more relevant.

Baffles are used for shape control and should not be interpreted as increasing rated loading capacity.

4. Confirm the Fertilizer Condition

Granular compound fertilizers can differ in particle size, flowability, moisture sensitivity and caking tendency.

These properties affect how the bag fills and how material later discharges.

Material information should therefore be confirmed before the final FIBC structure is selected.

5. Evaluate Fabric and Structure Together

Do not evaluate the product only by its 180gsm fabric weight.

The current structure also specifies ≥1500N warp and weft fabric strength.

Fabric GSM, mechanical strength, internal baffles and the lifting system should be reviewed together.
