Technical data sheet Extrachrome WS 90 Coated one-side papers > Specialty labels

Product description

One-side coated, supercalendered paper for self-adhesive labels. Extremely high gloss, high brightness and opacity. Wet opacity to ensure good outlook of label in wet conditions. Wet strength and caustic resistance ensure the usability for returnable bottles or products otherwise requiring wet strength properties. Runs smoothly on converting lines. Optimal printability in narrow web printing systems.
