Detailed requirements regarding the acceptable amount of ingredients migration is calculated on the basis of the global and specific migration. The above requirements are included in Health Ministry directives regarding substances which can be used in the process of production of materials and methods of checking their compliance with established limits. Migration is the gross mass of organic/metallic substances (global migration) or particular compounds (specific migration) which permeate to foodstuffs from packaging under specified conditions of time and temperature. Tests offered by our laboratory are based on requirements contained in Health Ministry directives as well as standards regarding the global migration testing or specific compound migration i.e. phenol, formaldehyde etc.
Model liquids used for testing as well as conditions of time and temperature are chosen according to standardization documents and legal regulations depending on the package destination. For example for liquid foodstuffs with high content of fat, low pH, for single and many fold use etc.
Methods used for migration assessment are:
