I have a question regarding migration tests. My company produce plastic packaging for food with several structure layer. Our customer always ask us for migration test report. The problem is, we not test all of our plastic packaging product due to cost and we had almost 20 different material structure. for example:
- PET/ PE/ Foil/ LLDPE
- PET/ LLDPE
Based on the above structure, LLDPE is the material which is directly contact with food. And, we had done migration test for PET/ LLDPE.
My question is:
If customer request us migration test for PET/ PE/ Foil/ LLDPE, can we give our customer migration test result of PET/ LLDPE?
