What Is the Best Adhesion Promoter for UV Inks
- 2026-08-01 10:23:15
- admin
When UV ink comes off during a tape test, the primer is often blamed first. However, poor adhesion can also result from the film surface, contamination, incomplete primer drying or incorrect UV curing. Here, “adhesion promoter” refers to a primer applied before printing. No single grade is suitable for every plastic film. Choose the Primer by Substrate PET and BOPET films often benefit from a prim...

- admin
Printing problems on plastic film do not always come from the same part of the process. Ink may shrink immediately after transfer. A printed layer may look normal but fail a tape test after drying. Some problems only appear after water exposure, rubbing or when the press reaches normal production speed. During troubleshooting, it is useful to record when the defect first appears before changing se...
