Food Packaging and human health

Food packaging is highly essential for protecting and handling food from farm to fork. However, packaging is also a source of chemical contamination of food.

What is in contact with food?

Food packaging consists of many different materials and combinations thereof, e.g., plastics, paper and board, metals, glass, adhesives, coatings, printing inks.

Not only packaging, but also other items contact food – collectively they are known as food contact articles.

What becomes part of the food?

Some chemicals transfer from food packaging into the food. This process is called chemical migration. Packaging material, type of food, temperature, and storage time are factors affecting the migration of chemicals.

Concerns and knowledge gaps

Consumers are constantly exposed to mixtures of chemicals migrating from food packaging.

Some chemicals commonly found in food packaging have been associated with certain diseases. The toxicity of many chemicals used in food packaging is not completely understood or even not known at all.

Such knowledge gaps may hinder a full safety assesment of food packaging.

Consumer expectations and legal requirements?

In many countries, it is required by law that packaging shall not compromise the chemical safety of food.

However legislation does not provide guidance on how to fulfill these requirements.

What can You do?

Reduce chemical migration by understanding the principles

Chemical migration increases at higher temperatures Heat (and microwave) foods in suitable inert containers.

In general, migration levels
increase over time. Limit
migration by shortening the
storage time of foods.

Small packaging formats have a high surface-to-volume ratio enabling higher migration levels. Avoid small portion sizes.

Many chemicals migrate at higher levels in fatty and-or acidic foods than in aqueous foods.
