How does circular colored copperplate label paper perform in high or low temperature environments?

The performance of circular colored copperplate label paper in high or low temperature environments is mainly influenced by factors such as paper material, coating, and printing ink. The following is a detailed analysis of its performance in different temperature environments:

1、 Performance in high temperature environment

Heat resistance:

Copperplate paper typically can withstand high temperatures ranging from 150 ° C to 200 ° C. Beyond this temperature range, copperplate paper may experience deformation, color changes, or burning.

Circular colored copperplate label paper may undergo changes in its internal fiber structure at high temperatures, resulting in reduced mechanical strength and folding resistance.

Ink stability:

High temperature can reduce the viscosity and increase the fluidity of ink, which may cause uneven transfer of ink and affect the printing effect of label paper.

The solvents or water in the ink will evaporate faster, causing the ink to dry faster, which may result in weak adhesion of the ink layer or dirt on the back.

Coating changes:

High temperature may cause changes in the coating material of the label paper, such as softening, peeling, etc., thereby affecting the clarity and durability of the label.

2、 Performance in low temperature environment

Low temperature resistance:

Copperplate paper has good low-temperature resistance and can generally remain stable between minus 20 degrees Celsius and minus 30 degrees Celsius. However, as the ambient temperature further decreases, the flexibility and strength of copperplate paper may be affected to some extent.

In extremely low temperature environments, the molecular chains of copperplate paper may become stiff, resulting in reduced flexibility. In addition, low temperatures may cause moisture in copperplate paper to freeze, thereby affecting its strength and printing effect.

Ink and coating stability:

In low-temperature environments, the properties of ink and coating materials may change, such as reduced ink flowability and increased brittleness of coating materials, which may affect the printing effect and durability of label paper.

Dimensional stability:

Low temperature may cause changes in the size of the label paper, such as shrinkage or deformation, which can affect the adhesion and readability of the label.

3、 Comprehensive recommendations

Choose the appropriate label paper:

Select appropriate circular colored copperplate label paper based on the temperature range of the actual application scenario. For label paper that needs to be used in high or low temperature environments, products with corresponding heat resistance or low temperature resistance should be selected.

Optimize printing process:

During the printing process, it is important to control the printing temperature and drying temperature reasonably to ensure stable printing quality and paper performance.

Use high-quality ink and coating materials to improve the durability and clarity of label paper.

Storage and Protection:

When storing circular colored copperplate label paper, ensure that the environment is dry and the temperature is appropriate, and avoid prolonged exposure to extreme temperature environments.

For printed label paper, appropriate protective measures should be taken, such as using protective film or storing it in a dedicated container, to prevent it from being damaged.

In summary, the performance of circular colored copperplate label paper in high or low temperature environments is influenced by various factors. In order to ensure the reliability and durability of label paper, it is necessary to select suitable label paper according to actual application scenarios, optimize printing processes, and take appropriate storage and protection measures.
