II. Types of Acrylic Resins (1) Classification by Thermal Behavior (Film-forming Characteristics): ① Thermosetting Acrylic Resins: Based on acrylic monomers as their fundamental components, these resins undergo further reactions—either among their own functional groups or with active functional groups in other resin systems (such as amino resins, epoxy resins, polyurethanes, etc.)—during the heati...

How Waterborne Polymers Improve Flexographic Printing Quality
- 2026-05-07 14:50:35
- admin
In flexographic printing, the performance of waterborne polymers and resin systems directly affects ink stability, color consistency, adhesion, and production efficiency. Traditional water-based inks may cause anilox roller clogging during long production runs, leading to unstable ink transfer and interrupted printing. In comparison, UV flexographic inks cure instantly under UV light, helping redu...

Poor Ink Adhesion on BOPP and PP Films / A Top Coating Can Help
- 2026-06-05 18:37:46
- admin
BOPP, PP, OPP, and PE films are widely used in flexible packaging, labels, and decorative applications due to their transparency, chemical resistance, and stable processing properties. However, printing on these films isn’t always straightforward. A printed surface may look fine initially, but problems can appear during tape tests, rewinding, die-cutting, or transport. Ink may peel, scratch, or lo...

Why Ink Adhesion and Rub Resistance Matter in Packaging Printing
- 2026-06-10 17:41:44
- admin
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...
