In a cold environment, the viscosity of self-adhesive materials has the characteristic of weakening with the temperature. Often customers reflect the glue is not sticky as well as fly labeling, labeling and other issues are related to temperature.
Let's Talk about the use of self-adhesive in winter:
# Storage ambient temperature
The storage ambient temperature of the label should not be too low. Self-adhesive materials placed outdoors or in cold environments can easily lead to frostbite of the material, especially the adhesive portion. If not properly restored, the adhesion of the self-adhesive will be lost or lost as a result.
# Processing environment temperature
processing environment temperature is very important for the material can be processed smoothly. If the temperature is too low, the viscosity of the material will be reduced, and then there will be poor printing, die-cutting fly marking, as well as slitting fly marking and labeling, affecting the smooth processing of the material.
#Labeling ambient temperature
labeling ambient temperature should meet the product requirements. First of all need to introduce the concept: self-adhesive products labeling temperature is the lowest ambient temperature can be labeling operation. Self-adhesive products use the temperature refers to the label on the surface of the labeled object to play after the sticky (usually takes 24 hours), can be applied to the ambient temperature range. In the case of labeling temperature requirements to meet the normal labeling, labeled with self-adhesive labels can be used in the use of products within the temperature range. Any kind of self-adhesive material has a relevant labeling temperature, below the temperature, self-adhesive adhesive glue viscosity to play a restricted, will lead to labeling sticker is not firm, warping and other issues.
# Label storage
in cold areas this is very important. If due to transportation, storage conditions can not meet the requirements, and lead to the label itself at a lower temperature, or even frostbite, although the labeling environment temperature to meet the requirements, due to the inability to recover in time, self-adhesive adhesion will also be affected. Therefore, in the above circumstances, processing or labeling operations before the labeling material should be preset in the labeling environment for a period of time, so that the temperature of the labeling material itself has to rise, so that the viscosity is restored.
# After labeling precautions
after the completion of the labeling, self-adhesive labeling material adhesion usually need a period of time (usually 24 hours) to gradually reach the highest value. It is not advisable to put the container or product that has just been labeled into an environment with a large difference in temperature immediately (even if the environment meets the temperature range of the self-adhesive material). Otherwise, the adhesion of the glue will be affected. And, film labels and containers will be due to temperature changes and thermal expansion and contraction, paper labels are more prone to paper fiber moisture or water loss and deformation of the phenomenon. These changes are not conducive to the glue to play the best labeling performance.
# Labeling precautions
labeling should also pay attention to the labeling pressure control and the cleanliness of the labeled surface. A suitable labeling pressure, that is, to ensure that to meet the pressure-sensitive self-adhesive labels pressure-sensitive properties, but also can be discharged between the label and the labeled surface of the air. Thus, the labeling that is strong and flat. The cleanliness of the labeled surface is also an important factor in ensuring the adhesion of the label and the flatness of the label after lamination.
