The glue of the tape is the key to determine whether a tape product is good. The current tape product market basically uses pressure-sensitive adhesives. As a professional tape manufacturer, Kunshan Yuhuan Package Materials Co., Ltd. will give you a brief introduction to this pressure-sensitive adhesive.

Since its invention, pressure-sensitive adhesive has undergone long-term development and evolution, and now has many different types. Among them, emulsion-based, solvent-based and hot-melt pressure-sensitive adhesives play a major role. Solvent-based acrylic pressure-sensitive adhesives are mainly prepared from ethyl acetate and toluene-based solvents, soft monomers, hard monomers, and functional monomers through polymerization. The solvent has a significant effect on viscosity and reaction speed. The performance of the pressure sensitive adhesive can be adjusted by changing the ratio of monomer and solvent. This pressure-sensitive adhesive has high initial viscosity, fast drying, and good water resistance. It is widely used in stationery tape, packaging tape and double-sided tape.

Next is the emulsion pressure-sensitive adhesive, which is mainly used to coat the surface of the substrate and form a pressure-sensitive adhesive film after drying. This kind of adhesive is closely related to people's daily life, and is currently one of the most widely used and most produced adhesive varieties. However, although the emulsion pressure sensitive adhesive uses water as the solvent and is relatively environmentally friendly, it has problems such as slow drying speed and migration of emulsifiers. With the development of people's environmental awareness and technology, the third generation of pressure-sensitive adhesive products, hot-melt pressure-sensitive adhesives, appeared.

Compared with the first two pressure-sensitive adhesives, hot-melt pressure-sensitive adhesives are solvent-free, more conducive to environmental protection and production safety, improved production efficiency, and reduced production costs. Therefore, the development momentum is very strong, and countries all over the world are vigorously developing this pressure sensitive glue. Hot-melt pressure-sensitive adhesives are currently used in products such as BOPP tape, sealing paper tape, and flame retardant tape.
