How will self-adhesive copperplate label paper change at different temperatures?

Self-adhesive copper plate label paper will show different changes at different temperatures, and these changes are mainly affected by its glue characteristics and paper material. Here are the changes:

First, conventional temperature range (5℃ to 40℃)

In the conventional temperature range, self-adhesive copper plate label paper is usually able to maintain stable performance. Within this temperature range, the adhesive is moderate in viscosity, and can be firmly pasted on the surface of the item, and it is not easy to fall off or warping. At the same time, the printing effect of coated paper can also be well maintained, and the image and text are clear and well structured.

Second, high temperature environment

When the temperature exceeds the conventional range, especially in high temperature environments, self-adhesive copper plate label paper will show the following changes:

1.Glue changes: High temperature will make the glue of the self-adhesive become more viscous, resulting in the label is difficult to peel off or the entire self-adhesive sticker deformation. This will not only affect the use of the label effect, but also may cause the label to fall off.

2.Material change: High temperature may also lead to changes in the material of the adhesive, reducing the bonding performance. This change may be manifested as fuzzy label printing or poor contact, which affects the recognition and durability of the label.

3.Resistance to temperature limit: Although the copper sheet self-adhesive label can withstand a certain degree of high temperature, the specific temperature limit depends on the quality of the material and the process. In general, its temperature is limited to between 60 ° C and 80 ° C. However, some self-adhesive labels with special process treatment or high-quality materials may have higher high-temperature resistance.

Third, low temperature environment

Under low temperature conditions, self-adhesive copperplate label paper will also be affected:

1.Glue hardening: Low temperature will make the glue of the self-adhesive become more hardened, resulting in the adhesion of the self-adhesive is greatly reduced. This makes the self-adhesive label can not be fully attached to the item, and even the phenomenon of cracking and breaking of the coated surface may occur.

2.Increased labeling difficulty: When labeling in a low temperature environment, due to the hardening of the glue, the label may be difficult to closely fit the surface of the affixed object, increasing the difficulty of labeling and failure rate.

Fourth, precautions

1.Select the right material: Select the right self-adhesive copperplate label material based on the temperature conditions of the actual application scenario. For labels that need to be used at extreme temperatures, special materials with corresponding high or low temperature resistance should be selected.

2.Strictly control the storage and use temperature: Ensure that the self-adhesive label paper is stored and used within the appropriate temperature range to avoid long-term exposure to high or low temperatures that will cause performance degradation.

3.Comply with labeling requirements: In the labeling process, strictly follow the labeling requirements of the self-adhesive label to ensure that the label can be firmly pasted on the surface of the item and maintain a good use effect.

In summary, the change of self-adhesive copperplate label paper at different temperatures is mainly affected by its glue characteristics and paper material. In practical applications, the appropriate material should be selected according to the specific conditions and the storage and use temperature should be strictly controlled to ensure the performance and use effect of the label.
