BOPP self-adhesive is a label material based on biaxially oriented polypropylene (BOPP) film. With its unique physical properties and technological advantages, it performs outstandingly in terms of both performance and effectiveness. Its surface is smooth and bright, featuring excellent water resistance, moisture resistance and oil resistance. It has strong chemical stability and can resist general acid and alkali corrosion. Moreover, it is light, thin, tough, scratch-resistant and tear-resistant, and can adapt to complex environments such as dampness and oil stains. In terms of printing adaptability, it supports various processes such as offset printing, flexographic printing, and gravure printing. The ink adheres firmly, and the colors are bright and long-lasting. It can also undergo post-processing such as lamination and hot stamping to enhance the texture of the label. In terms of bonding performance, when combined with different types of adhesives such as water-based glue and hot melt glue, it can be firmly adhered to smooth surfaces like plastic, metal, and glass. The initial adhesive force and holding force are balanced. Some products have removable features, and it is less likely to leave adhesive marks after being torn off. It is mainly used in scenarios such as food packaging (such as cookie and candy bag labels), daily chemical products (such as detergent bottle stickers), medicine packaging (moisture-proof labels), and express logistics (moisture-proof surface waybills). It can not only maintain clear information in damp and oily environments but also enhance the visual effect of product packaging with the high transparency and gloss of BOPP material. It is a commonly used label material that takes into account both functionality and aesthetics.
