Flexo Printing on Corrugated Boxes: Ink Selection Guide

Your corrugated box is more than just a way to keep things safe—it's your first chance to make a good impression on customers. No matter what you're shipping—electronics, snacks, cosmetics, whatever—the ink you choose for printing on the box can make or break how customers see your brand. From simple black logos to full-color designs that are ready for retail, flexographic ink is key to the look and performance of your packaging.
