In a high temperature environment, the round color copperplate label paper may undergo the following changes:
1. Color fading or discoloration:
High temperatures may accelerate the oxidation or decomposition of the ink on the surface of the label paper, resulting in lightening, fading, or unpredictable color changes. This change will affect the visual appearance and recognition of the label.
2. Material deformation:
Although coated paper has a certain degree of straightness, in a long time of high temperature environment, its fiber structure may change, resulting in paper deformation, curling or expansion. This deformation will affect the flatness of the label and the pasting effect.
3. Viscosity reduction:
High temperature may accelerate the aging process of adhesive and reduce its viscosity. This means that labels may fall off more easily at high temperatures or fail to stick firmly to the surface of the object being pasted.
4. Chemical changes:
Some chemical components on the label paper (such as pigments in ink, additives, etc.) may react chemically at high temperatures to produce harmful gases or substances that pose potential hazards to human health or the environment. However, it is important to note that coated paper label paper usually does not contain thermal chemical layers, so it will not disappear due to high temperature like thermal paper.
5. Physical performance degradation:
High temperature may also cause the physical properties of the label paper to decline, such as tear resistance and wear resistance, making it more likely to be damaged during transportation and use.
In order to deal with the impact of high temperature environment on circular color copper plate label paper, the following measures can be taken:
Select high-temperature label paper: In scenarios requiring high-temperature environment, select specially treated high-temperature label paper, which usually has higher heat resistance and stability.
Control the ambient temperature: Store the label in an environment with a proper temperature to avoid long-term exposure to high temperatures.
Strengthen the test: Before the label paper is put into use, the performance test is carried out in a high temperature environment to evaluate its high temperature resistance and possible changes.
In summary, the circular color copperplate label paper may change in color fading, material deformation, viscosity weakening, chemical changes and physical properties decline under high temperature environment. In order to cope with these changes, it is necessary to select the appropriate label paper, control the ambient temperature and strengthen the test.
