Flexible intermediate bulk containers (FIBCs), also known as bulk bags, are highly versatile and durable packaging solutions for large quantities of material. These containers are made from woven polypropylene tapes to form a strong fabric that can carry up to two tonnes. Being plastic-based, FIBCs are also recyclable and reusable, which means that stocks and inventory can be depleted quite quickly.

For many companies that frequently use FIBCs to transport and store their products, having a reliable inventory is essential. However, this takes careful planning and monitoring of stock levels to ensure that your business never runs out of bulk bags. Some companies simply don’t have time to do this themselves, so supplier-managed inventory is a brilliant alternative.

Custom Bulk Bags is a leading manufacturer and supplier of FIBCs in South Africa. We produce 3.5-million bulk bags per year and have a large stock available for customers that need basic FIBCs. For bespoke orders with various optional extras, then we will need a pre-defined lead time in order to deliver.

Let us manage your inventory

Our stock levels remain high throughout the year, allowing us to supply and deliver bulk bags to customers across the country. Vendor-managed inventory improves business efficiency and performance, but in many cases, it can help to reduce costs too. How can you tell if your business needs a managed service for its FIBC stock? Here are several signs:

  • Often running low on bulk bag stock or depleting inventory entirely.
  • Discrepancies between FIBCs purchased and FIBCs used.
  • You’re unaware of how many bulk bags you have in stock at this moment.
  • You’re not sure of how many FIBCs you will need every month.
  • Stock take is too laborious and time-consuming.
  • Inaccurate forecasting has led to overstocking.
  • Difficulties in meeting peaks in demand.
  • Issues with storage space at your warehouse or workplace.
  • Discarding old stock after a long period of time.

Why opt for supplier-managed inventory

A reliable FIBC supplier will deliver stock at regular intervals to ensure that your business always has just enough bulk bags available. This not only reduces the need for storage space, which saves warehousing costs, but it also allows your employees to focus on their core tasks without having to worry about inventory.

The extra space at your facility can also be used for other beneficial purposes, such as the expansion of capacity and output. A supplier-managed inventory system will minimise lead times and enable greater flexibility in meeting peaks in demand. You can rest assured knowing that you have enough bulk bags in stock when output is increased.

A good supplier will also handle the forecasting, depending on production cycles, which will reduce obsolete stock in your warehouse. Of course, this will require a detailed consultation or a series of discussions that will give us a good insight into your business and processes. This improved communication will also create a foundation of trust and mutual benefit for your business and Custom Bulk Bags.

Leave the administration and monitoring of inventory to us. Custom Bulk Bags will ensure that your company has optimal levels of stock year-round. For more information about our bulk bags, please contact us today.
