The internet has revolutionised almost every industry, including the bulk bag sector. Most businesses looking for flexible intermediate bulk containers (FIBCs) will use the internet to search for a reputable bulk bag manufacturer and supplier. They will then compare quotes online and get in touch with their chosen supplier.

This online process offers convenience and transparency. It allows companies to get a more accurate quote, depending on their needs. If the business is unsure of what specifications to order with its bulk bags, then it should talk to an expert from the FIBC supply company. As a leading bulk bag manufacturer in South Africa, Custom Bulk Bags will be able to guide customers towards the best product and optional extras for their needs. 

Custom Bulk Bags, a division of Custom Extrusion Pty Ltd, has been a significant bulk bag manufacturer in South Africa over the past twenty years. We not only convert woven polypropylene into bulk bags but we extrude and weave our own world-class polypropylene fabric too. Some of our customers include Sasol, Omnia, Tongaat Hulett and Illovo.

We are available for consultations and are happy to talk through our range of bulk bags with customers. Our sales team has in-depth knowledge of the industry and we can ultimately find the ideal bulk bag to suit your specific requirements. Here are certain things that you should know before requesting a quote from a bulk bag supplier.

Know your product

This seems obvious, but you need to know what product you want to store and transport in bulk bags. You need to know what it’s made of, how it may react to heat, light, moisture and friction. Knowing your own product in-depth will allow us to provide a more accurate quote with all the necessary optional extras. Do we need to provide splashproof inner linings, UV-protection on the exterior fabric, or can we provide a simple woven polypropylene FIBC with no frills? 

Know your facility

The customer needs to know two things about their premises, as these can influence the type of FIBC supplied. Know how the bulk bags will be transported – either by using a forklift, crane or another type of machine. This will influence the types of loops and handles required on your order of bulk bags. 

Secondly, know how the FIBCs will be loaded and discharged. Custom Bulk Bags offers a range of filling and discharging attachments, from sealed and spouts to duffel top and full-bottom discharge. Depending on the filling and discharge methods used at your facility, we will then tailor your bulk bags to match your needs.

Everything you need to know about breathable bulk bags

Know your industry

This is highly relevant if you’re in the food or pharmaceutical industries, or if you need bulk bags to store and transport hazardous materials and waste. These sectors are held to much higher standards when it comes to handling materials. This means that we need to supply bulk bags with special treatments that adhere to industry regulations.

We may need to include anti-static coatings, additional moisture-proof inner linings and chemical treatments to the exterior coating that will prevent the product from spoiling. Food-grade bulk bags and those used to store hazardous materials need to be safe and completely inert to prevent them from reacting with the stored materials within. Knowing these factors will allow us to provide you with an accurate quote.

Know your quantities

If you want to save more time, then try to calculate (or estimate) the quantities of materials that you need to store or transport. This will cut down the lead time and enable us to provide bulk bags with the ideal volume and weight specifications. If you have an idea of your monthly or annual quantities, we can also ensure that we have enough products in stock to supply you at regular intervals.
