How is the stickiness of Self-adhesive Label achieved?

Publish Time: 2024-03-08
The stickiness of Self-adhesive Label mainly comes from the special adhesive coated on its back. This adhesive allows the label to adhere firmly to various surfaces through its specific chemical properties and physical structure.
First, we need to understand the basic makeup of adhesives. Adhesives usually consist of resins, tackifiers, softeners and antioxidants. These ingredients are carefully proportioned and mixed to create an adhesive with specific viscosity and other properties.
Among them, resin is the main component of the adhesive, which determines the basic properties of the adhesive. The choice of resin will directly affect key indicators such as the adhesive's viscosity, holding power, and peel strength. Tackifiers are used to improve the adhesion of the adhesive so that it can better adapt to the surface characteristics of various objects to be attached. Softeners are used to adjust the viscosity of the adhesive to maintain stable performance during coating and use. Anti-aging agents are used to improve the aging resistance of adhesives and extend their service life.
When the adhesive is applied to the back of the label, a special microstructure forms on its surface. This structure can form close contact with the surface of the object to be attached, thereby generating strong adhesion. At the same time, the chemical components in the adhesive will also interact physically or chemically with the surface of the object to be attached, further enhancing the adhesion effect.
It is worth noting that different types of surfaces have different properties, such as smoothness, polarity, humidity, etc. Therefore, in order to achieve good adhesion effect, it is necessary to select the appropriate adhesive type and coating process according to the characteristics of the object to be adhered.
In addition, the viscosity of Self-adhesive Label is also affected by environmental factors such as temperature and humidity. In high temperature or high humidity environments, the properties of the adhesive may change, causing the label to become less sticky or fail. Therefore, when using Self-adhesive Label, you need to pay attention to the impact of environmental factors on its viscosity and take corresponding measures to prevent it.
To sum up, the stickiness of Self-adhesive Label is achieved by the special adhesive coated on its back. This adhesive forms close contact and interaction with the surface of the object to be adhered through its specific chemical properties and physical structure, thereby generating strong adhesion.
