Low Migration Products for UV-Curable Inks

Sartomer's new range of low migration specialty acrylate monomers and oligomers for food packaging and specialty coatings applications are fully assessed according to Swiss Ordinance, Nestlé Guidance Notes on Packaging Inks and EuPIA regulatory guidelines. This means they have no risk of contamination and a very low potential for migration.

 

Our customers know that it is essential to ensure the quality of our products is consistent from batch to batch in order to meet regulatory compliance. That's why the development of our food packaging line is driven by a thorough selection of raw materials, strict process control and analytical quality control process to support tight specifications.

 

In addition to meeting indirect food packaging regulatory requirements, these specialty oligomers are the answer to many food packaging challenges. That's because they successfully promote adhesion to difficult substrates used in flexible food packaging. And they offer excellent cure response with UV, EB and LED systems.

These advanced low migration products enable formulators to achieve performance properties, such as:

  • Enhanced adhesion on to a wide variety of substrates
  • Flexibility
  • Hardness
  • Chemical resistance
