Bulk bags vary in size, material and physical components, which means that one bag does not necessarily suit all purposes. When looking for bulk bags, you need to consider your needs, including transport and storage methods, and then evaluate the options available to you. Custom Bulk Bags can guide you through this process and point you towards a solution that perfectly suits your requirements.

The right bulk bag will give you versatility and enable you to perform the transportation and storage tasks with greater ease. Our products have a minimum safety factor of 5:1, which means that they can safely hold at least five times their intended weight without breaking. Choose a bulk bag supplier that offers a quality guarantee and can deliver your bulk orders timeously.

Think about size first

The first consideration when looking for bulk bags is the size. You need to choose bags with the correct dimensions as this will allow you to store the correct volume or weight of material. If you use wooden pallets to transport your bulk bags, then opt for one that matches the surface area of the pallets, without hanging off the edges or leaving too much unused space.

If your raw material is heavy, such as mining ore, then select bulk bags that can carry the weight. Custom Bulk Bags can hold up to two tonnes safely. The correct size will help you to minimise product waste, maximise your profits and ensure the safety of all workers that handle the bags for storage and transport.

How much can a bulk bag hold

Consider the material types for your needs

Most bulk bags are made from woven polypropylene (PP) tape, but some can have additional materials, such as waterproof coatings or electrostatic protection. These additional materials help to prolong the shelf life of products within the bags or to improve the safety of filling and discharging materials that are static or flammable.

Ask your supplier about additional materials that you may need, such as splash proofing, spark proofing, antistatic coatings or grounding pins. These options are vital to certain industries, such as chemical manufacturing, that use bulk bags to ship dry powders, flammable materials or products that generate static when moved around.

How to assess the quality of a bulk bag

Look at optional extras

Bulk bags can be fitted with numerous optional extras that make filling, shipping and discharging more efficient. If you want to avoid spillage, choose a bag with a sealable duffel top. If you use a hopper to fill the bulk bag, choose a spout top that can attach to the hopper or discharge nozzle. If you have large raw materials, such as rocks, then an open-top bag is probably your best option as it allows for quick and easy filling.

As with filling, Custom Bulk Bags also have various discharge options that improve efficiency and minimise wastage. Our products can be ordered with a spout discharge or a whole bottom discharge. In addition, storing and transporting dry materials that are susceptible to moisture will require a splash-proof coating or an inner liner. These are optional extras that we can recommend for various purposes.
