The adhesion foil adheres to smooth surfaces without adhesive, through adhesion forces. These are based on physical interactions between the foil and the substrate, making it removable without residue and reusable. Typical materials are plasticized PVC foils or special polymer coatings, which enable static adhesion. Adhesion foils are often used for temporary labeling, window advertising, or protective applications. They adhere particularly well to glass, plastic, or painted surfaces, but lose adhesive strength in dusty or humid environments. In the industrial sector, they are used for flexible labeling solutions without residue. The advantage over conventional adhesive foils lies in the easy removal and reusability, which makes them more environmentally friendly. Adhesion foils are available in transparent or printable form and are suitable for short-term lettering or changing markings. Through special surface finishes, adhesion and reusability can be optimized.
