Metodyka oznaczania migracji globalnej do wodnych płynów modelowych z opakowań z tworzyw sztucznych zgodnie z zaleceniami Komisji EWG
[Method of determination of global migration from the plastic packings to the water model fluids according to EEC recommendation]

ABSTRACT

Samples of polypropylene, polyethylene, polystyrene foils, softened polyvinyl chloride foils and laminates, in which polyethylene or EVA copolymer or SULRYN ionomer formed the inner layer were subjected to tests for determination of the global migration to aqueous fluids using model methods: chamber test, bag test, immersion test and lining test. The tested materials comprised 37 samples of packaging materials. The tested samples were not exceeding the range of permitted global migration into aqueous model fluids as recommended by the EEC directives. The obtained results fell significantly below the accepted limit of 10 mg/dm².
