Technical data sheet Intact WS 80 Coated one-side papers > Specialty labels

Product description

One-side coated, supercalendered paper for wet-glue labels. Popular also in use as pressure sensitive labels. Appealing brightness and high opacity. Medium gloss level. Wet opacity to ensure good outlook of label in wet conditions. Reliable printing and high-speed labelling. Ideal for returnable bottles. Wet strength and caustic resistance properties ensure good label wash-off. Suitable for both glass and PET bottles.
