Frequently Asked Questions

What is UV flexo ink?

UV flexo ink is a UV-curable flexographic ink used in narrow web label and packaging printing. It cures instantly under UV lamps, producing a hard, durable, high-gloss surface, and is the dominant ink technology in US self-adhesive label printing.

What UV flexo inks does TriWill supply?

TriWill Group supplies standard UV flexo ink, cationic UV ink, opaque white inks (for sleeves and shrink), low migration UV flexo ink for food packaging, and high density UV flexo ink — covering every narrow web label and packaging application.

What is the difference between free radical and cationic UV flexo ink?

Free radical UV inks are the standard for most label applications. Cationic UV inks continue curing after UV exposure, offer excellent adhesion to difficult substrates, and have low odour — making them suitable for specialty applications. TriWill supplies both.

Does TriWill supply low migration UV flexo ink?

Yes. TriWill Group offers TWG-FXU-LMI, a low migration UV flexo ink formulated for food packaging applications requiring migration compliance.

What substrates do UV flexo inks print on?

UV flexo inks print on a wide range of self-adhesive label stocks, films, and packaging substrates. Contact TriWill Group with your specific substrate for ink recommendations and application guidance.
