  1. Testing Procedures for UN Rated Bulk Bags All bulk bags, also known as FIBC, jumbo bags, or super sacks, undergo rigorous performance tests. However, UN approved bulk bags are of superlative standards that survive the physical pressure of loaded contents, which are often hazardous in nature. In this blog, we will take a closer look at how these jumbo bags can meet UN safety guidelines to ensure secure usage and handling

  2. What Are UN Rated Bulk Bags? The agrarian, construction and chemical industries often need to handle chemicals and flammable or toxic products. UN certified bulk bags are heavy-duty packaging bags that help these businesses safely store and transport hazardous materials. It is to minimize risks of freak accidents during storage or transportation of such products that these bags must meet UN’s special testing standards. Fine powders like salt, sugar, and flour, that risk damage from moisture, find appropriate packaging solutions in bags with liner or with lamination.

  3. Testing Procedures That UN Rated Bulk Bags Must Go Through - The following are some testing procedures that all big bags must take to be certified as UN FIBC bags. Top Lift Test A hydraulic cylinder is used to press down the contents in the bag that is tested. The top lift is used to test if the FIBC bag can withstand six times its level of safe working load for five full minutes to qualify for a UN rating.

  4. Stacking Test In this procedure, the bag is placed on a flat surface and is filled with contents to safe working load. Pressure, which is equivalent to two similar bags, is then applied to the bulk bag to check if it withstands the stress over the next 24 hours • Drop Test • The FIBC bag is filled to a safe working load level and then dropped from a specified height that will depend on the testing requirements of the packing group. To qualify the test for UN approval, the bag should not tear midway, nor should there be any leakage of contents.

  5. Topple Test The tested bag is filled to a safe loading level on a platform. The platform is then gradually raised in a way that the bag is forced to tumble down without letting its contents escape. This is to test if the sack can resist a 100 mm long knife cut when it is loaded to safe capacities. The tear cannot widen beyond 25% and cause the contents to overflow. The bulk bag is put on a vibrating platform for one hour to check if it stays intact without toppling over, or causing any breakage. • Tear Test • Vibration Test

  6. Righting Test The jumbo sack is filled to its safe loading capacity and then knocked on its side. It is righted into position to see there is no damage or tear to the bag or its contents. If you want UN approval for your FIBC bags to store and carry potentially dangerous industry materials, Umasree is a UN certified bags manufacturer in India that you can trust.
