You have just purchased our open-top, flat-bottom big bag — the most versatile FIBC format for aggregates, rubble, and bulk products — and this guide explains how to get the most out of it from the first use cycle. You will learn how to prepare, load, hoist, and maintain it to extend its service life on site.
Below, you will find the technical specifications, the step-by-step procedure, recommended complementary products, and maintenance guidelines that will extend the lifespan of your big bag.

Step-by-step guide for use
Follow this procedure from the first time to safely integrate the bag into your operations and take advantage of the 5:1 safety factor it is designed with.
Inspect the bag before use
Unfold the big bag on a clean surface and visually inspect the four loops, base seams, and fabric body. Check for tears, punctures, or loose seams. A 30-second inspection before loading prevents a 1500 kg drop during hoisting.
Position the bag on a pallet
Place a clean and sturdy pallet (ideally 1.0 × 1.2 m) in a clear area and center the bag on top. Lift the four loops upwards, holding them with guides or with an operator at each corner; this keeps the top opening open and vertical during filling.
Load material through the open top
Pour the material using a mechanical shovel, conveyor belt, or manually. Distribute the load evenly so that the bag maintains its cubic geometry and does not exceed the 1500 kg payload capacity. Avoid loading the bag off the pallet: if it shifts, the center of gravity becomes unbalanced.
Prepare the bag for hoisting
Ensure that all four loops are free of obstructions and accessible from above. If the bag will be exposed to rain, cover it with a tarp; the open-top model does not close on its own. Verify that the crane or forklift operator confirms the operation before hoisting.
Hoist using all four loops simultaneously
Always use a spreader bar or central hook that distributes tension evenly among all four loops. Never hoist by holding only two opposite loops or a single loop with a direct hook: this concentrates the load in one area and can break the seam, even if the weight is within the limit. Lift slowly and verify stability before moving the load.
For rubble removal operations, do not fill the bag directly on the ground: a sharp stone or metal fragment can puncture the bottom during loading. Always place a pallet or rigid cardboard as a base; you will easily gain 2-3 reuse cycles.
Doubts about your bag's maximum load?
If you need to verify if your specific material (wet rubble, fine sand, biomass) is compatible with the 1500 kg payload or if you require another model from the family, ask the Dodom Virtual Assistant.
Complementary products
To get the most out of your open-top big bag, consider these complementary products. The big bag with a skirt is the alternative when you need protection against rain or wind. Manual stretch film and its dispenser allow you to secure the pallet with several filled bags for stable transport.
Maintenance and care
A well-maintained big bag can be reused for several cycles; one that is poorly stored will fail on the first lift of the second use. These guidelines are what extend the bag's useful life the most:
- After emptying the bag, shake it to remove dust and particles. Inspect seams and handles before folding for reuse.
- Store folded in a dry and shaded area. Prolonged direct UV radiation degrades polypropylene and reduces the effective safety factor.
- Do not reuse the bag if you detect cuts in handles, open seams, or perforations in the base. A failure during lifting never gives advance warning.
Never lift the big bag by only two handles or a single handle with a direct hook. The 5:1 safety factor is calculated on the sum of all four handles working together; using only two can cause the seam to break even if the weight is within the limit.
Frequently asked questions
Can I reuse this big bag multiple times?
Yes, as long as the seams and all four handles are intact. Inspect it before each new cycle: 5-8 reuses is reasonable for clean debris and aggregates; less if the material is abrasive, sharp, or has been exposed to the sun for weeks.
Is an open-top big bag rain-resistant?
The polypropylene fabric allows water to pass through the open mouth and the micro-pores of the fabric. If the bag will be left outdoors with a risk of rain, cover it with a tarp or consider the model with a top skirt, which does allow the top to be closed.
Can I stack full big bags one on top of another?
It is not recommended unless expressly certified by the manufacturer for stacking. This bag is designed for lifting, not for supporting additional vertical weight. If you need to stack, do so in columns of a maximum of 2 bags, on a firm and flat surface.
