ISO 25765 Printing Ink Migration Analysis in Flexible Packaging

The ISO 25765 standard provides a comprehensive framework for the analysis of printing ink migration from flexible packaging into food products. This service ensures that printed labels and graphics on food contact materials do not contaminate the contents with harmful substances, thereby safeguarding consumer health and maintaining product integrity.

Flexible packaging is widely used in the food and feed sectors due to its barrier properties, lightweight nature, and ability to extend shelf life. However, the presence of printing ink on these packages can lead to migration of potentially hazardous substances into the packaged goods if not properly controlled. This service focuses on quantifying such migrations by simulating real-world conditions that a package might encounter during storage and distribution.

Testing adheres strictly to ISO 25765, which outlines standardized methods for determining the amount of printing ink transferred from packaging into foodstuffs under specified temperature and time conditions. The process involves placing labeled samples in contact with model foods or simulants that mimic the properties of various food types.

The testing apparatus typically consists of a controlled environment chamber where the flexible packaging containing the printed label is immersed in these simulant liquids. Over predefined periods, the amount of ink transferred to the liquid is measured using analytical techniques such as gas chromatography or mass spectrometry. These methods allow for precise quantification of the migrated compounds.

The results provide critical insights into whether the printing process has adhered to regulatory requirements and best practices. This information is essential for quality managers, compliance officers, R&D engineers, and procurement teams responsible for ensuring product safety and maintaining brand reputation.

Industry Applications: Food manufacturing companies, packaging designers, and regulatory bodies.
Use Cases and Application Examples: Ensuring compliance with international standards like ISO 25765; verifying that printing processes do not compromise the safety of packaged food products; providing data for label design optimization.

Benefits

The primary benefit of this service lies in its ability to protect consumers from potential health risks associated with harmful substance migrations. By identifying and quantifying these migrations early in the product development cycle, food manufacturers can make necessary adjustments to their packaging and printing processes.

In addition to enhancing consumer safety, compliance with ISO 25765 standards also helps businesses avoid costly legal ramifications and negative publicity that often accompany non-compliance. This service ensures that products meet stringent regulatory requirements set by authorities worldwide, including the US FDA, EU regulations, and others.

For R&D engineers and quality managers, this testing offers valuable data for iterative improvements in printing technologies and package design. The insights gained can lead to more efficient processes, reduced waste, and enhanced product performance.
