In packaging and label printing, a good printed surface is not only about bright color. It also needs to stay firmly on the substrate during rewinding, cutting, lamination, transportation and daily use. Some common problems are familiar to many ink manufacturers and printers: ink peels off after tape testing, the printed surface is easily scratched, color becomes uneven, or the ink layer loses str...

How Do You Select the Right Tg for a Water-Based Acrylic Label Adhesive
- 2026-07-22 18:56:18
- admin
When formulating a water-based acrylic pressure-sensitive adhesive for labels, Tg is usually one of the first parameters we set. It indicates whether the dry adhesive film will behave relatively soft or firm at a given temperature and influences initial tack, peel adhesion, holding power, low-temperature performance and adhesive ooze. However, Tg alone does not determine whether an adhesive is sui...

How to Reduce Pinholes in PTFE Coatings with PFA 001 Dispersion
- 2026-09-03 15:43:32
- admin
Poor surface smoothness, low gloss, and microscopic pinholes may occur during the spraying and baking of waterborne PTFE non-stick coatings. These defects can allow steam, fats, and corrosive substances to penetrate the coating over time, increasing the risk of blistering, peeling, and reduced non-stick performance. Why Pinholes May Form Pure PTFE has extremely high melt viscosity and limited flow...
