What is the best flexo ink for food packaging?

Water-based flexo ink and low-migration UV ink are the best options for food packaging due to their safety, low VOC emissions, and compliance with FDA and EU regulations.

Is water-based flexo ink safe?

Yes, water-based flexo ink is considered safe and environmentally friendly. It is widely used for food packaging because of its low VOC content and non-toxic formulation.

What is low migration flexo ink?

Low migration flexo ink is specially formulated to minimize the transfer of substances from packaging into food, making it suitable for sensitive applications like food and pharmaceutical packaging.

What is the difference between water-based and UV flexo ink?

Water-based flexo ink dries through evaporation and is eco-friendly, while UV flexo ink cures instantly under UV light, offering higher print quality and durability.

How do I choose the right flexo ink?

Choosing the right flexo ink depends on substrate material, printing speed, end-use requirements, regulatory compliance, and desired print quality.
