Dynacel: High Rub and Grease Resistant Water-Based Ink for Tableware
DYNACEL is an advanced water-based ink specifically engineered for flexographic printing on paper tableware, including napkins, single-use tablecloths, food bands, and service bags. Its technical architecture, built upon high-adhesion acrylic vehicles and stable pigmentation, delivers exceptional performance against dry and wet rub, alongside outstanding resistance to oils and grease. It is the definitive solution for the HORECA channel and take-away services, where color transfer and structural staining must be eliminated during real-world consumer handling.
Operational Advantages on Press
- High dry and wet rub resistance: Radically minimizes ink transfer during stacking, industrial handling, and final product use by the consumer.
- Superior oil and grease behavior: Ensures color stability and prevents staining when in contact with typical fatty food components.
- Industrial processability and fast drying: Features a wide processing window with stable rheology, enabling high-speed production lines without compromising print quality.
- Consistent optical quality: Achieves clean solid areas, sharp typography, and excellent mottle and halo control, even on highly porous paper or kraft substrates.
