Chemical producers have a lot of safety concerns at all stages of their operations, including the final transportation phase where their products leave the factory. There are numerous safety regulations to which they must adhere in order to protect their employees and customers. Storing and transporting chemicals is no different, so a credible bulk bag supplier is key to safety during this stage.

Custom Bulk Bags is a leading manufacturer and supplier of high-quality flexible intermediate bulk containers (FIBCs) for chemical producers. Our bags range in capacity from 500kg to two tonnes. All of our products have a minimum safety factor rating of 5:1, which means that they can safely carry at least five times their intended load before failing.  This is critical for chemical producers and their employees.

Whether it’s organic elements or dangerous chemicals, these manufacturers need to use reliable and high-quality packaging solutions for their bulk chemicals. Not only will this prevent accidents and injury, but it will also minimise spillages and contamination. Polypropylene bulk bags are ideal for these requirements and offer an inert packaging solution for a wide range of chemicals.

Why polypropylene is ideal for FIBCs

Custom Bulk Bags are made from high-quality polypropylene tapes that are extruded by our sister company, Integrated Polypropylene Products (IPP) in Durban. IPP has been running successfully for over 40 years, supplying its own woven materials to a variety of other industries. These polypropylene tapes are woven together to create the flexible, durable and strong fabric for our bulk bags.

Polypropylene is a highly inert polymer that makes it perfect for various chemicals, even those that are corrosive. Our bulk bags offer superior protection against water, moisture, fire and even static electricity. This provides peace of mind for shipping and storing hazardous substances and reactive chemicals.

Our products are incredibly durable and strong, which is why they are trusted by fertiliser manufacturers and other chemical producers in South Africa. They are a great packaging solution for bulk quantities of acids, bases, granular chemicals and hazardous waste products.

UN-certified bulk bags for chemical producers

Our FIBCs are UN-certified for various chemicals and hazardous waste products. In addition, Custom Bulk Bags has held ISO 9001 accreditation since 2007, so the quality of our products has stood the test of time. Our products are manufactured to strict standards for safety, quality and durability.

These certifications are a guarantee to our customers that their products will be stored in a safe and reliable container. We also offer custom printing on our FIBCs so that chemical producers can clearly label the contents of the bulk bags, which allows employees to identify chemicals and remain aware of the potential risks associated with handling the bags.
