Bulk bags, also called flexible intermediate bulk containers (FIBCs), are the perfect packaging solution for large quantities of materials. When you need to transport or store bulk quantities of something, consider FIBCs as an affordable, durable and reusable solution. These products can be used to hold various types of materials, from crumb rubber and firewood to fertilizer and mining ore.

Crumb rubber is a fairly new material that is commonly used to create artificial turf and padded flooring in outdoor spaces. Many playgrounds, sports arenas and public spaces in South Africa use crumb rubber to create a durable, strong and cushioned surface. It’s a sustainable way to reuse old tyres and keep them out of landfills, which is why crumb rubber has exploded in popularity.

Construction companies and businesses that handle crumb rubber need an efficient and effective way to store and move it. FIBCs are ideal as they are easy to stack, handle and discharge. Custom Bulk Bags is a leading manufacturer and supplier of high-quality bulk bags in South Africa. We produce up to 3.5 million bulk bags annually that meet various international standards and regulations

Are bulk bags truly environmentally-friendly

Tips for storing crumb rubber in bulk bags

Unlike most dry products, crumb rubber is not uniform in grain size – the bits of rubber vary in size, from around one centimetre across to less than a millimetre. This means that it can be tricky to handle, especially when loading or emptying storage containers. Bulk bags provide an easy way to fill and discharge through the use of special attachments and spouts, which reduce spillage and maximise the efficiency of the containers.

Our FIBCs can be customised to meet your specific needs, including attachments, inner liners, lifting loops and external coatings. If you’re going to store your bulk bags outside, we’d recommend adding a UV coating to the external fabric of the FIBCs. This will prevent sun damage and maximise the lifespan of the bulk bag.

The best option is to cover bulk bags that are stored outside while construction takes place. This can either be done with a tarpaulin or a temporary roofing structure. This will also protect them from the other elements, although bulk bags are made from woven polypropylene tapes, so they are highly moisture-resistant.

Safety hazards to consider for handling carbon materials

Crumb rubber has a high carbon content and can present certain safety hazards. Carbon-based products must be handled carefully by employees, so storing them becomes a greater concern. One solution is to use batch inclusion bulk bags instead of regular ones. These are special FIBCs that can be melted in a hopper along with the carbon material, which minimises the risks posed by unpacking and handling the products.

It’s more efficient and safer for employees to use batch inclusion FIBCs when working with flammable or carbon-based products that need to be incinerated. When it comes to crumb rubber for construction projects, regular bulk bags will suffice. Our expert consultants will be able to guide you through the ordering and specification processes to help you pick the perfect FIBC for your needs.
