Bio-renewable ink formulations
Featured products for regulatory compliance
Many of today’s top-performing lithographic inks contain products that include DAP (diallyl-phthalate). DAP is not suitable for Nestlé and Swiss compliant indirect food packaging.
To help our customers comply with current regulations, Sartomer developed phthalate-free replacement blends.
