Model food contact articles

Challenge test A test of the effectiveness of a super-clean recycling process to remove chemical contamination from materials or articles. The test involves introduction of exaggerated levels of surrogates and includes as an end parameter the migration evaluation of these surrogates from a model food contact article. 

Procedure B has been developed and proposed by Fraunhofer IW (Franz et al. 1994) without incorporating model contaminants. It is a black-box approach which monitors inherently present recycling-related substances and is applicable to a ready-to-use food contact article. In this way, the procedure meets not only the R D and quality assurance requirements of the manufacturer but also offers a test possibility for enforcement labs. Essentially, procedure B consists of two experimental key steps ...
