Hi everyone,

 

Does somebody know which kind of in house test can be done for rPET in food packaging environment? For virgin materials, I accept CoC but rPET is easier to be tampered. Could be density a good idea? 

 

Thanks,

 

Maria

The carboxylic end group (COOH) will increase for each recycling step

 

Usually reported as the equivalent concentration/ton of polymer

 

It is done on 100% virgin resin and increases
