4.  French Law 2012-1442 (24/12/2012)
Printing inks & varnishes formulated with raw materials containing Bisphenol A (BPA) applied to the
outside surface of a food packaging are affected by the application of the French law on BPA.
By consequence, for all products used in applications without functional barrier, all RM based on BPA
have to be substituted.
 Nestlé Guidance Note on Packaging Inks (Version: August 2016)
Ban of BPA based raw material status : French market & Nestlé applications

• Conclusion:
• For the French packaging market or for Nestlé applications, food packaging without any functional
barrier, should be printed with UV inks free of raw materials based on BPA.
‘’General exclusions for ink formulations:
This Note has negative lists of components. The components below are allowed by the Swiss
Ordinance, but are forbidden for Nestlé ink formulations due to quality and safety concerns…
… Bisphenol A (BPA) and materials manufactured from or incorporating BPA in reacted form as
part of the chemical structure must not be used.’’
