What Are The Precautions For Using Self-adhesive Labels In Winter?

In a cold environment, the viscosity of the self-adhesive material has a characteristic that decreases as the temperature decreases. The quality of Adhesive labels is closely related to the external environment, especially the external temperature. Generally, if the temperature is too high or too low, the sticker will not be firmly attached. So when we paste Self-adhesive Labels in winter, we have a lot of things to pay attention.

 First, the labeling environment temperature should meet the product requirements: normal labeling under the condition of meeting the labeling temperature (10 °C -25 °C), and the product with the self-adhesive label after 24 hours can be used within the operating temperature range (generally -5 ° C - - 40 ° C) for use. Any self-adhesive material has a related labeling temperature below which the adhesive viscosity of the self-adhesive is limited, which may result in problems such as poor labeling and lifting.

Second, the storage environment temperature of the label should not be too low: the self-adhesive printing material is placed outdoors or in a cold environment, which can easily lead to frost damage to the material, especially the glue. If not properly restored, the tackiness and processability of the sticker will be lost or lost.

 Third, the label preset processing: This is very important in cold regions. If the temperature of the label itself is low due to transportation and storage conditions, and even frostbite, even if the labeling ambient temperature meets the requirements, the viscosity and processing properties are also affected due to the inability to recover in time. Therefore, in the above case, before the processing or labeling operation, the label material should be preset in the labeling environment for a period of time (more than 24 hours), so that the temperature of the label material itself rises, and the viscosity and processing performance are restored. .

Fourth, the labeling should also pay attention to: labeling pressure control and cleaning of the surface to be attached. A suitable labeling pressure ensures that the air between the label and the surface being applied is removed. Thus, the label is firmly and flattened. The cleaning of the surface to be attached is also an important factor in ensuring the tackiness of the label and the flatness after lamination.

5. After the labeling is completed: the tackiness of the Waterproof Stickers Labels usually takes a while (usually 24 hours) to reach the highest value. Moreover, film-type labels and containers will expand and contract due to temperature changes, and paper labels are more prone to moisture or water loss of paper fibers. These changes are not conducive to the best performance of the glue.
