They are ideal for securely labeling products, documents, and inventory, for safety and warning notices, for circular sticking, as test labels, or sealing labels for indoor use. Environmentally friendly, these high-quality, chlorine-free bleached specialty paper labels are PEFC certified and feature a solvent-free, pressure-sensitive adhesive. They are 100% recyclable with waste paper, and the packaging is made from recycled cardboard. They deliver excellent printing results on all laser and inkjet printers, copiers, color laser printers, and color copiers. Smooth processing is ensured thanks to the fully secure edge and optimal flatness.
