In cold environments, self-adhesive materials have the property of becoming less sticky as the temperature decreases. Problems such as glue not sticking as well as dropping labels are often temperature related.

The following 6 points are very important for the use of self-adhesive label in the winter:

1 Label Storage Environment Temperature should not be too low

When self-adhesive materials are placed outdoors or saved in cold environments, it is easy to cause especially the glue part of the frostbite. Without proper recovery, the adhesive and processing properties of self-adhesive will be lost permanently.

2 The Temperature of the Processing Environment is Very Important

If the temperature is too low, the viscosity of the material is reduced, there will be poor printing, die-cutting waste with labeling, as well as drop labeling, affecting the processing of the material.

3 Labeling Environment Temperature should Meet the Product Requirements

Any kind of self-adhesive material has a minimum labeling temperature. Glue viscosity of label will be affected when it is processed lower than minimum labeling temperature. It will lead to sticker warping and other problems.

4 Label Pre-Processing, which is very Important in Cold Areas

If transportation and storage conditions of self adhesive material can not meet the requirements, which will lead to the label itself at a low temperature, or even frostbite. Although the labeling environment temperature can meet the requirements, due to the labeling state can not be restored in a timely manner, self-adhesive adhesive and processing performance 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 more than 24 hours, so that the temperature of the labeling material itself is able to rise, so that adhesion and processing performance is restored.

5 After the Labeling is Completed, the Adhesion of Self-Adhesive Labeling Material usually Takes a Period of Time (usually 24 hours) to Gradually Reach its Maximum Value

Just labeled containers or products should not be immediately put into the temperature difference in the environment (even if the environment to meet the use of self-adhesive materials temperature range).

Otherwise, the adhesion of the adhesive will be affected. And, film labels and containers will be  changes and thermal expansion and contraction due to temperature. Paper labels are easier to paper fiber moisture or water loss and deformation of the phenomenon. These changes are not conducive to the glue for play the best labeling performance.

6 Pay Attention to the Labeling Pressure Control and Ensure the Surface of the Labeling is Clean!

A suitable labeling pressure, both to ensure that to meet the pressure-sensitive properties of self-adhesive labels, but also can be discharge the air between the label and the surface to be affixed, so that the label is affixed to both firm and flat.

The cleanliness of the labeled surface is also an important factor to ensure the adhesion of the label and the flatness of the label after lamination.
