Every company that uses bulk bags has expectations. The ideal container should be able to hold large volumes of material safely, be able to stack neatly and withstand bumpy transport without toppling over. These three factors form the foundation of any good bulk bag. To ensure that they can perform as expected, bulk bags are put through a string of tests, including a topple test.
Custom Bulk Bags is a leading manufacturer and supplier of high-quality bulk bags in South Africa. Our products undergo rigorous testing to ensure that they meet international standards and regulations for quality, safety and efficacy. All of our products have a minimum safety factor rating of 5:1. They are approved for a variety of uses, including the storage of hazardous materials, mining ore and agricultural products.
How the topple test works
This evaluation determines how well a bulk bag can stay upright during bumpy transport, whether by road, rail or sea. In most cases, a bulk bag falling over is costly as it not only potentially spills its contents which leads to waste, but it can also put workers at risk if those contents are hazardous.
Certain chemicals or flammable materials need to be stored in sealed bulk bags, but if they topple over, it can compromise the seams and closures. This is why the topple test is a vital aspect of a container’s safety. The test itself is very simple – a bulk bag is filled to maximum capacity and placed on a platform. It is then toppled over.
The height of the platform can vary depending on the regulatory requirements of the materials being transported, but if the bag does not break or leak, it passes the topple test. Even if there are slight leakages from the seams or closures upon impact, it does not necessarily mean that the bag fails. Any significant breach of the fabric or seams will constitute a failure.
How to improve topple resistance
The first step used by manufacturers to improve topple resistance is to increase the weight of the fabric used at the top of the bag. A more rigid or sturdy top closure and lining will strengthen the seams and help to prevent rips as the bag impacts the floor. Additionally, manufacturers may include a band of extra fabric around the top perimeter of the bag for added structural support.
Including inner liners or different (stronger) types of top closures can also improve impact resistance. This is why it’s vital to consult with your bulk bag manufacturer before placing an order. Our team of experts will be able to guide you through a process to select the best optional extras for your requirements and ensure that your products are 100% suited to your business needs.
