How do create a good printing sample for migration
Additional Information for migration analysis
Establishing appropriate printing sample and dealing with them, are crucial for a meaningful migration analysis.
Certain conditions must be met, because it is not possible to do a rational analysis with any sample.
The following samples are generally required for the analysis :
Original substrate unprinted (blank)
The sample should have a minimum size of 22 x 22 cm (or 3 patterns a 11 cm x 11 cm for a multiple determination), and have sufficient ink coverage.
Furthermore, the samples should be wrapped in aluminum foil immediately after its creation. Do not bent and / or crumple the samples .
Packaging (roll to roll)
In this case, the patterns are to be wound separately on a sleeve . Again, the samples must be wrap in aluminum foil.
The labels should (each 3 pattern printed and unprinted ) with a minimum size of 11 cm x 11 cm and have have adequate coverage .
We recommend (if possible) to send the empty original container to which the label will be applied.
When creating samples for analysis in the field of molding pressure
(e.g. yoghurt pots ) the cups should packed in a stack of 20 and put in aluminium foil.

Please check with your customers , ifs recycled cardboard was used for food packaging.
Important: The laboratory must be informed about the kind of food, which will be packed in the beverage. This is important for the correct election of food stimulant.
