    Migration of Chemical Compounds from Packaging Polymers

    The migration process can be divided into 4 major steps: diffusion of chemical compounds through the polymers, desorption of the diffused molecules from the polymer surface, sorption of the compounds at the plastic–food interface, and desorption of the compounds in the food (Ferrara and others 2001). The mass diffusion process is usually

  • migration of chemical compounds from packaging polymers

    Migration of Chemical Compounds from Packaging Polymers

    Possible chemical migrants include plasticizers, antioxidants, thermal stabilizers, slip compounds, and monomers. Chemical migration from food packaging is affected by a number of parameters including the nature and complexity of food, the contact time and temperature of the system, the type of packaging contact layer, and the properties of the

    Food packaging and migration - ScienceDirect

    Using food simulants for testing the migration of chemical compounds from food packaging includes two steps. The first one is the exposure of the polymer packaging to the food simulant(s), which then allows the compounds from the packaging material to migrate into the simulant(s).

  • migration of styrene from plastic packaging

    Migration of styrene from plastic packaging

    Migration of potentially toxic substances from plastic packaging materials is very important in the food industry since it determines the suitability of polymers when used in food packaging. In this work, results are presented on the migration of styrene monomer from plastic packaging based on either rigid or foamed polystyrene.

    Improving the prediction of exposure to chemicals from food

    The focus was on the migration of the chemical compound benzophenone from low-density polyethylene. The study revealed how specific foods and packaging polymers interact (mathematics of transfer of components from packaging into foods) to better predict migration and ultimately exposure to chemicals from food contact materials.

    Migration of substances from food packaging materials to

    The employment of novel food packaging materials has increased the number of occurring hazards due to the migration from packaging material to the packaged food. Although polymers have mainly monopolized the interest of migration testing and experimentation, recent studies have revealed that migration also occurs from "traditional" materials generally considered to be safe, such as paper

    Also, migration modeling applies assumptions and simplifications about the migration process, the FCM, and the chemical migrant, and may thus overestimate or underestimate actual migration. Further, the migrating chemical and its initial concentration in the packaging have to be known in order to model its transfer from the FCM to the food.
