Knowing the main distinctions between ventilated and conductive bulk bags is essential when ordering these large packaging products. Also called flexible intermediate bulk containers (FIBCs), bulk bags enable the safe and effective transportation and storage of goods throughout South Africa.

As a top producer of FIBCs, Custom Bulk Bags is committed to offering you the best packaging options to meet your unique requirements. We provide a reliable and affordable storage and transportation option for a variety of goods used in a number of South African sectors. Our products can safely hold between 500kg and two tonnes of material per bag. 

Raw materials used to manufacture bulk bags

What are conductive bulk bags?

The purpose of conductive bulk bags is to keep static electricity from building up while being transported and stored. They are perfect for items that are categorised as explosive or flammable, like chemicals (sulphur, coal dust, or specific fertilisers) that come in powder, granule, or flake form.

Some pharmaceuticals and even food powders, such as flour, sugar and cocoa, also have the potential to ignite or combust. In these instances, conductive bulk bags are needed. We manufacture Type C anti-static bulk bags that prevent electrical charges from building up while the products are handled. 

Conductive bulk bags are made from a special type of fabric that securely disperses static charge to the ground because it is woven with conductive threads, such as carbon or stainless steel fibres. To further reduce static build-up, conductive bulk bags frequently include grounding straps or loops that attach to a grounding system.

To ensure compliance with safety requirements, reputable producers, such as Custom Bulk Bags, clearly brand conductive bulk bags with the international grounding symbol and required certificates. Conductive bulk bags stop electrostatic discharge, which can harm delicate components, so these bags actually protect the integrity of your items.

Are bulk bags truly environmentally-friendly

What are ventilated bulk bags?

Ventilated bulk bags allow air circulation within the bag. They are designed to facilitate appropriate ventilation and avoid moisture build-up. These large bags are perfect for goods that can become spoiled or grow mould when there is a buildup of moisture, including agricultural products, such as grains, coffee beans and seeds.

Wood pellets and sawdust also have the potential to leak moisture during storage; however, by allowing this moisture to escape, ventilated bulk bags help keep the material from clumping or decomposing.

Ventilated bulk bags can also be used in the pharmaceutical industry. To preserve their effectiveness, several pharmaceutical medications need specific moisture levels to be maintained. Bulk bags with ventilation can aid in controlling this moisture content.

Ventilated bulk bags are made from a woven fabric that has mesh panels or breathable strips to promote airflow. By allowing trapped moisture to escape, the breathable design stops mildew and mould from growing on the objects that are being stored. Good ventilation keeps products that are prone to spoiling fresh and of a high quality.

Selecting the best bulk bag

Now that you are aware of the primary distinctions between ventilated and conductive bulk bags, the following elements should be taken into account:

  • Product characteristics – List the particular attributes of your product, such as its moisture susceptibility, flammability, and ventilation requirements.
  • Conditions for storage and transportation – Take into account the environmental aspects of storage and transportation, including humidity, temperature, and possible exposure to rain or other elements.
  • Safety standards and regulations – Different businesses may have different rules about what kind of bulk bags are needed for secure transportation and storage.

Essential features of a quality bulk bag

Benefits for South African businesses

Bulk bags offer numerous advantages. Firstly, they are highly versatile. To accommodate a wide range of product types and weights, bulk bags are available in a variety of sizes, capacities, and designs. They are made from high-strength, woven polypropylene fabric, which provides excellent defence against rips, punctures, and inclement weather.

Bulk bags allow companies to maximise storage space and cut labour expenses by making product handling and loading/unloading easier than with sacks or other traditional packaging techniques. Their cubic shapes make them easy to stack and store inside warehouses and containers.

Bulk bags are an affordable option for storing and shipping large amounts of goods when compared to other packing materials. They are cost effective to manufacture and can be recycled at the end of their useful life. This makes bulk bags an attractive option for companies with environmental goals and targets.
