How does copperplate adhesive label perform under extreme temperature differences?

The performance of copperplate adhesive labels is relatively stable under extreme temperature differences, but it may also be affected to some extent. The following is a detailed analysis of the performance of copperplate adhesive labels under extreme temperature differences:

1、 Temperature resistance performance

The temperature resistance range of copperplate adhesive labels varies depending on the type of adhesive used. Generally speaking, the temperature range for the use of water adhesive copperplate paper labels after 24 hours of labeling can reach -50 ° C to+90 ° C, while the temperature range for the use of hot adhesive copperplate paper labels is -15 ° C to+65 ° C. This means that copperplate adhesive labels can maintain a certain level of performance over a wide temperature range.

2、 Specific manifestations under extreme temperature differences

High temperature environment:

In high temperature environments, the adhesive of copperplate adhesive labels may soften due to heat, resulting in weakened or detached adhesion of the labels. However, compared to other types of labels such as thermal paper labels, copperplate adhesive labels perform more stably at high temperatures. Thermal paper labels are prone to fading or disappearing of printed content after exceeding a certain temperature.

In addition, high temperatures may also cause changes in the ink on the surface of copperplate adhesive labels, such as color fading or fading, but this usually takes a longer time and higher temperatures to occur.

Low temperature environment:

In low-temperature environments, the adhesive of copperplate adhesive labels may become hard and brittle, thereby affecting their stickiness. Especially under extreme low temperature conditions, such as minus tens of degrees Celsius, the viscosity of the label may significantly decrease, leading to difficulties in labeling or label detachment.

Low temperature may also cause shrinkage or deformation of the label material itself, thereby affecting the flatness and printing effect of the label. But compared to paper labels, copperplate adhesive labels perform more stably at low temperatures and are less likely to deform due to temperature changes.

3、 Response measures

Choose the appropriate type of adhesive: Choose the appropriate type of adhesive based on the usage environment to ensure the adhesive stability of the label under extreme temperature differences.

Optimize labeling process: Before labeling, ensure that the surface of the object being labeled is clean and flat to improve the adhesion and stickiness of the label. At the same time, appropriate labeling pressure and speed should be used to ensure that the label can be firmly attached to the object being labeled.

Consider using special materials: For labels that require long-term use in extreme temperature environments, copper plate adhesive materials with higher temperature resistance range or special coatings can be considered.

In summary, the performance of copperplate adhesive labels is relatively stable under extreme temperature differences, but it is still necessary to pay attention to selecting appropriate adhesive types, optimizing labeling processes, and considering the use of special materials to improve their adaptability and durability.
