Samolepicí

Samolepicí is a Czech term used to describe materials and products that adhere to surfaces through a pressure-sensitive adhesive layer, enabling sticking without water, heat, or mechanical fasteners. The typical construction includes a substrate (paper or various films), a thin adhesive layer, and a protective release liner that is removed before application.

Common backings are paper, polypropylene, or polyester, while the adhesive is usually acrylic or rubber-based. The release liner, often silicone-coated, protects the adhesive until the moment of use. After application, light pressure helps the adhesive establish contact with the surface, forming bonds that allow the material to stay in place under ordinary conditions. Performance depends on factors such as surface roughness, temperature, humidity, and the chemical compatibility between the adhesive and the substrate.

Applications encompass a wide range of products and formats, including self-adhesive labels, stickers, tapes, protective films, and mounting sheets. They are widely used in packaging, product labeling, electronics, automotive, medical, and signage industries. In packaging, self-adhesive labels are common for applying product information, branding, and barcodes. In other contexts, self-adhesive films protect surfaces or provide temporary mounting.

Advantages of samolepicí products include easy and quick application, clean removal (in many cases), and the elimination of moisture or heat activation. Potential drawbacks include the possibility of adhesive residue on removal, varying performance with surface texture or temperature, and environmental considerations related to adhesive chemistry and liner disposal.
