dear all:

 

What´s the point to do migration tests for plastics packaging of freeze products, if migration is based on molecular movement, and under freeze temperatures this is neglected?

 

tnks for your input

According to chapter, table 3 of EUR-Lex - 02011R0010-20200923 - NL - EUR-Lex (europa.eu) testing needs to be done for 10 days at 20 degrees Celsius for any food contact at frozen and refrigerated conditions, so apparently, it's not negligible enough...

I understand the UE regulation, that´s why I´m asking.

Basic thermodynamics states that molecular movement is low, and, as per UR regulation from -15ºC (freeze condition) to +20 is not representative of molecular dynamics
