Extremely strong adhesive labels on A4 sheets, self-adhesive. They adhere twice as strongly as conventional paper labels, even on critical surfaces such as damp, warm, cold, rough, or dusty surfaces. Ideal for secure labeling of products, documents, and inventory, as well as for safety and warning notices, wrap-around labeling, inspection stickers, or closure labels for indoor use. Environmentally friendly: made from high-quality, chlorine-free bleached special paper, PEFC-certified, with a solvent-free adhesive. Labels are 100% recyclable with waste paper, and the packaging is made of recycled cardboard. They provide very good printing results on all laser and inkjet printers, copiers, color laser printers, and color copiers. Trouble-free processing is ensured due to the all-around safety edge and optimum flatness.
