Extremely strong adhesive labels on A4 sheets, self-adhesive. They stick twice as strongly as conventional paper labels, even on critical surfaces such as damp, warm, cold, rough, or dusty areas. Ideal for securely labeling products, documents, and inventory, as well as for safety and warning notices, re-labeling, inspection stickers, or closure labels for indoor use. Environmentally friendly: made from high-quality, chlorine-free bleached specialty paper, PEFC certified, with a solvent-free adhesive. The labels are 100% recyclable with waste paper, and the packaging is made from recycled cardboard. They provide excellent printing results on all laser and inkjet printers, copiers, color laser printers, and color copiers. Hassle-free processing is ensured by the all-around safety border and optimal flatness.
