Consumer protection requires that harmful chemicals are prevented from reaching food products or pharmaceuticals designated for human consumption. Packaging keeps products fresh and protects against direct contamination; however, materials used to manufacture the packaging can be an unintended source of migrating chemicals. To perform routine migration studies, food producers, or packaging suppliers, need to determine barrier properties of primary food packaging.
