What is Food-Grade Ink and Why It Matters?
Food-grade ink refers to inks that are certified safe for indirect food contact. These inks are specifically formulated to ensure that they do not pose any health risks when used in food packaging.
Relevant safety standards:
- FDA (USA): The Food and Drug Administration sets stringent guidelines for materials that come into contact with food.
- EU 1935/2004: This regulation ensures that materials intended for food contact do not transfer constituents to food in quantities that could endanger human health.
- Swiss Ordinance: Similar to EU regulations, it governs the safety of materials used in food packaging.
- GB (China): The national standard for food safety in China, ensuring compliance with health regulations.
Dangers of using regular ink:
Using regular ink for food packaging can lead to serious health risks, including chemical migration and contamination. These inks may contain harmful substances that can leach into food products, posing a threat to consumer safety.
Types of Safe Inks Used for Food Packaging
Water-Based Inks
Water-based inks are an excellent choice for food packaging due to their low volatile organic compounds (VOCs) and environmentally friendly nature. They are particularly suitable for uncoated kraft paper and can be used with flexographic and digital presses, such as LUNAJET.
UV-Curable & Low-Migration UV/LED Inks
These inks offer fast drying times and durable colors, making them ideal for coated or barrier-lined paper. However, it is crucial that they comply with low-migration certifications to ensure safety.
Edible Inks
While edible inks are used for direct food printing, such as on cookies or cakes, they are not the same as food-grade ink for packaging. Edible inks are designed to be consumed, whereas food-grade inks are safe for indirect contact.

Choosing the Right Paper for Safe Printing
Selecting the appropriate paper type is essential for safe printing. Options include kraft, uncoated, and barrier-coated papers. It is vital to match the ink and paper absorbency to ensure optimal print quality and safety.
Printing Techniques for Custom Paper Bags
Flexographic Printing
Flexographic printing is ideal for large volume runs and high-speed production. This method allows for efficient printing on various paper types, making it a popular choice for custom food bags.
Digital Inkjet Printing (incl. LUNAJET)
Digital inkjet printing is suitable for short runs and offers vibrant color accuracy and flexible customization options. This technique is particularly beneficial for businesses looking to create unique designs without the need for large quantities.
Screen Printing
Screen printing is a budget-friendly option for low-volume orders. It is ideal for solid or simple designs, making it a practical choice for smaller businesses or specific promotional items.
Ensuring Food Safety & Certification
To guarantee food safety, it is essential to conduct migration testing and obtain third-party lab certifications, such as those from the FDA, EU, or GB. Good Manufacturing Practices (GMP) should be followed, and shelf-life control is typically around 12 months for ink. In some cases, the use of barrier paper layers may be necessary to enhance safety.
Real-Life Applications & Case Studies
Custom food paper bags have a wide range of applications, including bakery bags, hot food takeaways, and promotional food packaging. A notable case involves the combination of kraft paper, barrier layers, and LUNAJET digital printing, which successfully meets both safety and aesthetic requirements.
