Colourlessness of dyed plastic materials
According to the 24th Communication on the Examination of Plastics, Bundesgesundheitsblatt 15 (1972), there are "(...) no objections to the use of colourants for colouring plastics and other polymers for consumer goods (...) provided that the colourants (...) do not pass on to the foodstuffs even in visible proportions (...) when the consumer goods are used as intended". This requirement can be easily checked with the test available here.
In short — AI-generated
This test determines whether colorants migrate from dyed plastic packaging into food simulants. The material is brought into contact with a test medium under defined conditions, and the medium is subsequently checked for any visible discoloration.
The result indicates whether the packaging meets the regulatory requirements for color fastness in food contact applications. It confirms that the material does not release colorants into food, ensuring compliance with safety standards for consumer goods.
