How is the stiffness of the thermal label paper

The stiffness of thermal label paper is an important performance indicator, which directly affects the flatness, durability and performance of the label during use. The stiffness of paper is affected by many factors, including the thickness of the paper, the fiber structure, the coating formula and the production process.

Influencing factors of paper stiffness

1.Paper thickness:

Generally speaking, the thickness of the paper is proportional to its stiffness. The thicker the board, the higher the stiffness. This is because increased thickness provides better support and resistance to bending.

2.Fiber structure:

The fiber structure of the paper also has a significant effect on its stiffness. Papers with tightly packed fibers and uniform structure tend to have higher stiffness.

3.Coating formula:

The formulation of the thermal coating and protective layer on the thermal label paper will also affect its stiffness. The proper coating formulation can provide additional support and protection, thereby increasing the stiffness of the paper.

4.Production process:

The process steps such as calender and drying in the production process will also affect the stiffness of the paper. Proper processing can improve the flatness and stiffness of the paper.

Thermal label paper stiffness characteristics

Moderate stiffness: Thermal label paper usually needs to have a certain stiffness to ensure that it is not easy to deform or curl during printing, pasting and use. However, the stiffness should not be too high so as not to affect its flexibility and foldability.

Adjust according to the use: Different use scenarios have different requirements for the stiffness of thermal label paper. For example, in the need for higher flatness and durability, you can choose a higher stiffness of thermal label paper; In the case of better flexibility, you can choose products with moderate stiffness.

Stiffness test method

For the test of paper stiffness, it is usually measured by a professional stiffness tester. These instruments can simulate the bending situation during actual use and objectively evaluate the stiffness of the paper.

conclusion

In summary, the stiffness of thermal label paper is a performance indicator affected by a variety of factors. When selecting thermal label paper, you need to select the appropriate stiffness level according to the specific use scenario and requirements. At the same time, it is also necessary to pay attention to the preservation environment and transportation conditions of the paper to avoid a decline in the stiffness of the paper due to external factors.

It should be noted that because different manufacturers and different specifications of thermal label paper may have differences in stiffness, it is necessary to evaluate and select according to the specific situation in practical applications.
