Make your Ink Stand Out with Cellulose Esters

The performance of an ink plays a vital role in the overall quality of flexible packaging.  Increased consumer spending in North America has led to a demand for packaging of superior quality.  Eastman™ Cellulose Esters give ink formulators the tools necessary to produce top quality inks for the rapidly expanding packaging market.

Why use Eastman™ Cellulose Esters? The Difference is Clear

Improved Performance

  • Better adhesion to packaging films
  • Excellent cold-crack and heat resistance
  • Resistance to grease
  • Outstanding flow, leveling, & wetting

Enhanced Appearance

  • Fewer surface defects
  • Improved gloss
  • Better UV resistance (non-yellowing)
  • Excellent pigment orientation

Increased Productivity

  • Faster solvent release
  • Improved blocking performance
  • Better intercoat adhesion
  • Increased print speeds

Formulating with Eastman™ Cellulose Esters

Eastman™ CAB and CAP can be used in inks for a variety of printing operations including gravure, flexographic, offset, and ink jet.  They are compatible with most common solvents and acrylic monomers and provide a much safer option for a letdown vehicle, co-resin, or additive than traditional nitrocellulose.  Many grades of Eastman™ CAB and CAP are compliant with Swiss Ordinance on Materials & articles in Contact with Food (SR 817.023.21).  See the table below for grades recommended for food safe printing inks.
