Inks for Food Product Marking, Coding, and Packaging

Manufacturers are turning to industrial inkjet printing for marking and coding of food products with variable data to meet increasingly stringent food industry regulations for tracking products with lot codes and precise expiration information.

Brands also produce shorter-run packaging for variations in sizes, unique flavors, and customization for regional marketing that supports changing consumer demand and tastes. Inkjet printing offers the most cost-effective workflow for product versioning.

The primary concern for food companies regarding any ink they use on products or packaging is the need to prevent contamination through ink migration. Ink must be evaluated and validated for compatibility with the packaging substrate and potential environmental interactions that could affect food safety and quality.

Marking and Coding

Inks used to mark and code products are typically applied to the outside of the product packaging in order to comply with industry regulations in various countries, and also to help consumers. Manufacturers must ensure that their packaging serves as a functional barrier that prevents any migration of the ink chemicals. Tin, aluminum, glass, plastic, and laminated materials are generally considered absolute barriers that prevent ink migration. Testing for any substrate is advised.
