21 Aug 2019 --- A lab study conducted by four European consumer groups has reportedly shown that food packaging made of colored paper and cardboard – such as coffee cups and straws – may contain and release harmful chemicals originating from the inks used for printing. The European Consumer Organisation (BEUC) – to which the four consumer groups belong – is calling for EU-wide laws regulating the use and safety of all paper and cardboard food packaging. With single-use plastics set to be banned in the EU as of 2021, the test raises safety concerns over some alternatives like paper straws, BEUC states.
