The role of tape adhesive

Many tapes are not sticky and need to rely on the adhesive on the back of the tape to achieve the purpose of sticking. The adhesiveness of the tape depends entirely on the adhesive, so the choice of adhesive is very important. Most tapes now use pressure-sensitive adhesives, so what are the advantages of pressure-sensitive adhesives? Come and learn it!

The pressure-sensitive adhesive also commonly known as self-adhesive. The academic definition is a kind of viscoelastic body that has both the viscous properties of liquid and the elastic properties of solid. This viscoelastic body has the influence, factors and properties of both the contact process and the destruction process of bonding. Simply put, its bonding process is very sensitive to pressure, so it is called pressure sensitive. Adhesive tape that uses pressure-sensitive adhesive as the back glue can be easily pasted on the surface of a smooth object, and when it is torn, it does not pollute the surface of the adhered object, that is, there is no residual glue.

The main components of pressure sensitive adhesives are divided into many types. Take an anti-slip tape from Kunshan Yuhuan Package Material Co., Ltd. as an example. The company uses acrylic pressure-sensitive adhesives. It is a resin-based pressure-sensitive adhesive. This type of pressure-sensitive adhesive has a colorless and transparent appearance and good weather resistance. It does not need to add a series of additives such as softeners and anti-aging agents to have good pressure-sensitive adhesive performance. The formula is simple . Moreover, this adhesive has no effect on the skin, and medical adhesive tapes often use this adhesive.
