Some properties of self-adhesive labels will change with changes in temperature and ambient humidity, mainly reflected in the strong adhesion and detachment force. Generally, consumers report that the super glue is not sticky, and problems such as flying marks and falling marks are all right. Temperature is related, therefore, for me from the self-adhesive label manufacturer, it is very important for the normal use of the label in all aspects.

1. Labeled storage temperature:

If the non-drying collagen is placed outdoors or in a low-temperature environment, it is easy to cause the raw materials, especially the glue, to be frozen. If it is not properly repaired, the stickiness and processing properties of the self-adhesive will be damaged or lost. The storage of different collagen materials is also more prominently affected by high temperature and high and low temperature. Under the influence of high temperature and high and low temperature, the fluidity of the self-adhesive will increase significantly, especially the fluidity of the hot-melt superglue will be greater, resulting in a decrease in the original viscosity of the superglue and an increase in the probability of glue leakage. It is recommended to store in an independent warehouse, the temperature is generally around 23°C, and the air humidity is generally around 55%.

2. Labeling working temperature:

The lowest labeling temperature of self-adhesive products refers to the lowest temperature at which the labeling operation can be carried out. The application temperature range of self-adhesive products is the index value. Hours), the working temperature range that can be used. Any non-drying collagen material has a relevant labeling temperature. Below this temperature, the adhesiveness will be significantly limited, which may cause problems such as instability and warping of the label. What needs to be emphasized here is: Affected by the surface energy of the object to be pasted, the degree of roughness, the curvature of the label, etc., an appropriate increase in the temperature of the label will be beneficial to the final effect of the label. Generally speaking, the label Working temperature at 23℃±l is super beneficial for labeling.

3. Logo preset solution:

This is critical in winter. If the temperature of the label itself is low due to transportation and storage conditions that cannot meet the requirements, or even when it is frozen, although the labeling temperature meets the requirements, because it cannot be repaired in time, the self-adhesive and processing properties will also be affected. Influence. Therefore, in the above-mentioned cases, before processing or labeling operations, the marking material should be preset in an environment above the lowest labeling temperature of this material for more than 24 hours, so that the marking material The temperature itself has been warmed up to a certain extent, so that the viscosity and processing properties have been restored. At the same time, the object to be pasted should be placed in the labeling environment for more than 12 hours, so that it can be done after the warming process Above the extremely low labeling temperature, it is beneficial for labeling.

4. After labeling:

It generally takes a period of time (usually 24 hours) for the viscosity of self-adhesive label materials to gradually reach the standard value. It is not allowed to put the well-labeled containers or products immediately in an environment with large temperature and humidity differences (even if the environment considers the temperature range of non-drying collagen materials). Otherwise, the full play of the strong adhesive will be affected. Moreover, plastic film labels, stickers, and containers will expand and shrink due to temperature changes; paper product labels are prone to moisture or water-deficient deformation of paper fibers. This change is not conducive to the full play of the best labeling characteristics of superglue. 5. When labeling, you should also pay attention to the pressure control of the label and the cleaning of the surface to be pasted. An appropriate labeling pressure can guarantee the pressure sensitive characteristics of the pressure-sensitive self-adhesive label, and can also discharge the gas between the label and the surface to be pasted, so that the label is firm and flat . The cleaning of the pasted surface is also an important factor to ensure the stickiness of the sign and the leveling after conforming.
