Food Packaging Materials
Irradiation of empty packaging is considered to be a manufacturing process and is not covered by regulation, other than those regulations that pertain to the suitability of packaging materials in general.
Packaging materials are commonly irradiated prior to being filled in a variety of businesses, including:
- dairy (cream, butter, eggnog, coffee creamer)
- processed foods (sauces, salad dressings, yogurt, processed meats, fruit gels)
- beverages (juice, wine)
- OTC pharmaceutical and health aids
- pharmaceutical
- medical device industries
Packaging materials are irradiated after being filled in the following categories:
- spices and herbs
- botanical and herbal preparations
- meat
- poultry
- fruit
- dry ingredients
- medical supplies
In either event, there is a long history of use of the irradiated materials with excellent results and no change in package integrity.
Availability
Packaging materials that are approved for irradiation in contact with food materials can be obtained from most major packaging suppliers. It is the responsibility of packaging suppliers to obtain approval for their materials and ensure that any treatment, including irradiation, does not alter the suitability of the packaging material. A list of approved packaging materials can be found in 21CFR § 179.45, Subpart C.
