Food Grade Ink vs. Food Safe Ink: What’s the Real Difference?
In the world of food manufacturing and packaging, ink plays a critical role in providing essential information such as expiration dates, batch numbers, and branding.
However, not all inks are created equal when it comes to safety and compliance with food industry standards.
Two commonly used terms in this context are food grade ink and food safe ink. While they might seem interchangeable, they serve distinct purposes. Here’s a closer look at their differences.
Food Grade Ink
What is food grade ink?
Food grade ink is produced for situations where the printed ink can come into direct contact with the food itself.
For example, certain food manufacturers may need to print directly onto products such as confectionery, baked goods or some types of fresh produce. In these applications, the ink must be manufactured using ingredients that are considered suitable for direct food contact.
Food grade inks are therefore designed with consumption in mind and must meet the relevant food safety requirements.
Typical features of food grade ink:
- Ingredients selected to be non-toxic and suitable for edible applications.
- Compliance with applicable food safety regulations.
- Use in industries such as confectionery, bakery and some fresh food applications.
- Formulations designed specifically for printing directly onto food.
Food Safe Ink
What is food safe ink?
Food safe ink is generally used for applications where the ink does not come into direct contact with the food, but is printed onto something associated with the food product.
Packaging is a common example. Ink may be printed onto a cardboard box, wrapper, label or container. While these materials can be close to the food, the ink itself is not intended to be applied directly to the edible product.
A major consideration with these inks is migration, this is the possibility of components from the printed surface transferring to the food. Food safe formulations are therefore designed with measures to minimise this risk.
Typical features of food safe ink:
- Formulations designed to limit migration.
- Compliance with relevant food packaging and safety requirements.
- Suitability for printing on packaging and other non-edible surfaces.
- Use on products such as boxes, wrappers, labels and containers.
Food Grade or Food Safe: Which One Do You Need?
The simplest way to understand the difference is to consider where the ink will be printed. If the ink is being applied directly to an edible product, a food grade formulation is required.
If the ink is being printed onto packaging or another surface that may be near or come into incidental contact with food, a suitable food safe ink is generally the appropriate choice.
The two terms should therefore not automatically be treated as interchangeable.
Why Choosing the Correct Ink Is Important
Selecting an ink based on the application is an important part of maintaining food safety and regulatory compliance. The wrong formulation could create a risk of contamination or migration and may contribute to more serious consequences, including product recalls and reputational damage.
For manufacturers, understanding the difference between direct and indirect food contact can help to ensure that the chosen ink is appropriate for both the product and the printing process.
Get Advice on the Right Ink
Every food production and packaging application is different, so choosing an ink should be based on how and where it will be used.
