The viscosity of the round color copperplate label paper mainly depends on the type of adhesive on the back, the coating process and the use of environment and other factors. In general, the stickiness of coated paper self-adhesive labels is strong and can meet the needs of most applications.
Specifically, the adhesive characteristics of coated paper self-adhesive labels can be summarized as follows:
1. Adhesive type:
Different adhesives have different viscous properties. Common types of adhesives include rubber based adhesives, acrylic based adhesives, etc. These adhesives have their own characteristics in terms of formula, adhesion, temperature resistance, water resistance, etc., and the appropriate type can be selected according to specific needs.
2. Coating process:
The coating process also has an important effect on the stickiness of the label paper. The high-quality coating process can ensure that the adhesive is evenly and stably coated on the back of the label paper, thereby improving the adhesive effect and durability of the label.
3. Use environment:
The stickiness of the label paper is also affected by the environment in which it is used. For example, factors such as temperature, humidity, the material and cleanliness of the surface to be pasted can affect the effectiveness of the label. Therefore, when using the circular color copper plate label paper, it is necessary to pay attention to the impact of environmental factors, and take appropriate measures to ensure the stickiness of the label.
For the specific viscosity test of circular color copperplate label paper, it is usually possible to evaluate its adhesion effect and durability by means of initial viscosity test and stickiness test. These test methods can help users understand the adhesive behavior of label paper under different conditions, so as to choose the label paper product suitable for their needs.
In summary, the viscosity of the circular color copperplate label paper is strong, but the specific viscosity performance needs to be considered according to the type of adhesive, coating process and use environment. When selecting and using, it is recommended to test and evaluate according to actual needs.
