In the food sector, it is aimed to keep the shelf life of the foodstuffs long, to protect the packaged foodstuffs from external influences, to ensure the integrity and quality of the foodstuffs, to ensure food safety and to ensure the traceability of foodstuffs. For this purpose, various packaging materials suitable for the foodstuff to be packaged are used.

Generally, paper, cardboard, glass, metal and plastic are used in the packaging of foods. Most of the materials used for packaging are active materials and cause migration. Migration from these materials to foodstuffs is only possible in case of contact.

Food packaging materials can be classified as follows:

• Impermeable packaging materials (eg glass, metal, ceramics and various alloys)
• Permeable packaging materials (eg plastics and rubber)
• Porous packaging materials (eg paper and cardboard)

In order to avoid migration, the packaging must be made of substances that do not interfere with the foodstuff inside. If the foodstuff to be contained is light sensitive, the light transmittance of the packaging material should be low. Or, if the foodstuff to be contained is sensitive to gases, the gas-tightness of the packaging material must be high.

Turkish Food Codex Communiqué on Food and Plastic Contact Materials (Communiqué no: 2013 / 2013) by the Ministry of Food, Agriculture and Livestock in 34 to regulate the principles of plastics and materials in contact with or likely to come into contact with food ). In the annexes of this communiqué, among the basic rules of total and specific migration tests, the use of E2-like simulant is permitted for the determination of the migration amounts of packaging materials used in the packaging of certain foodstuffs.

In the advanced laboratories, total migration analysis is carried out using E2-like simulant within the scope of package analysis. During these studies, standards and test methods published by national and international organizations are based.
