Custom printed poly bags serve as the first touchpoint for your brand. Achieving sharp flexographic printing on flexible poly film requires careful pre-press plate preparation, corona surface treatment, and precise ink viscosity management.
Why corona treatment is essential
Untreated polyethylene has low surface energy, causing ink to bead and flake off. Corona discharge treatment oxidizes the surface molecules, raising dyne levels and ensuring strong ink adhesion.
High-definition photopolymer printing plates
Using digital flexo plates allows fine line work, vibrant brand colors, and barcode readability even on high-speed roll-to-roll conversion machines.
