The strength and durability of flexible intermediate bulk containers (FIBCs) play a crucial role in the safe transportation and storage of bulk goods. Reputable bulk bag manufacturers will perform several rigorous tests on their products to ensure the highest levels of safety and quality. The tensile test is one such example that is used to assess the strength of the lifting loops and fabric.

Custom Bulk Bags is a leading manufacturer and supplier of FIBCs in South Africa. We produce up to 3.5 million bulk bags per annum, all of which have a minimum safety factor rating of 5:1 and are manufactured in accordance with international regulations and standards. We adhere to strict testing procedures and quality control processes to ensure that our customers receive exceptional bulk packaging products.

What is the tensile test?

The tensile test is a widely recognised method used to measure the strength and integrity of bulk bag components. It involves subjecting a sample of the bulk bag fabric or lifting loops to controlled tension until they reach the breaking point. By doing so, the test measures the maximum force that the material can withstand before failure.

The sample is typically cut into a specific shape and size and then pulled until it breaks. During the test, various factors are measured, such as elongation, force and load-bearing capacity. These measurements provide valuable insights into the performance and quality of the bulk bag and its individual components.

By identifying possible failure points and issues with the components, we can fix the design or strengthen the fabric before mass-producing the bulk bags. It allows FIBC manufacturers to improve the design and overall safety of their products. By batch testing, we can assure our customers of the quality of their bulk bags.

Importance of the tensile test for safety

As bulk bags are subjected to various forces during transportation, storage and handling, it is essential to determine how they will perform under load-bearing stress. A bulk bag that fails to meet the necessary strength requirements can lead to catastrophic consequences, such as product spills, equipment damage and worker injuries. 

By conducting tensile tests, Custom Bulk Bags can ensure that its FIBCs are capable of withstanding the demands of real-world applications. This helps to safeguard the goods being transported, protect assets and maintain a safe working environment.

When it comes to FIBC manufacturing, thorough testing procedures are crucial for maintaining consistent quality and adhering to international standards. Reputable manufacturers like Custom Bulk Bags understand the importance of these procedures and implement rigorous quality control measures to ensure that their products meet and exceed industry requirements.
