For polymers, the requirements for “Food Grade” are defined in the Code of Federal Regulations under Title 21- Food and Drugs, Part 177- Indirect Food Additives: Polymers. This section of the CFR calls out a list of approved generic ingredients and additives and some test methods to evaluate candidate polymer materials. There are requirements for several different types of polyethylene in Part 177, as listed in sub-parts 177.1610 through 177.1630.
