While many users of FIBCs may request an “FDA Approved” bulk bag, it is important to note that such a product does not exist. The Food & Drug Administration does not issue any approvals or certifications of FIBCs or FIBC liners. The FDA regulations that govern food contact can be found here.  With regard to polypropylene resin, a major component of most FIBC fabrics, FDA Food Contact Regulation 21 CFR 177.1520 states that they must be 100% virgin.
The topic of food safety in the packaging industry is constantly evolving, with tougher industry standards and increased government regulations (FSMA) becoming the norm. FIBCA recognizes that there are many adequate food safety processes, accreditations, certifications, and schemes for the production of FIBCs; and therefore recommends that all manufacturers, distributors, and users of FIBCs confirm that their process is adequate for each FIBC application.  While FIBCA does not endorse one food safety scheme over another, it does strongly support the effort of the Global Food Safety Initiative to establish a global standard.
