These are biaxially oriented polypropylene tapes with a high-strength, pressure-sensitive, water-based acrylic adhesive, ensuring a secure seal for packages. They offer excellent adaptability for sealing boxes of various corrugated board qualities and cardboard liners. The adhesive is environmentally friendly, solvent-free, and can be applied in a wide range of climatic conditions. It does not crystallize at low temperatures and does not liquefy at high temperatures, thus preserving the integrity of the packaging and its contents. The high quality is due to the water-based acrylic adhesive systems, which increase in adhesion over time.
