Preservation Mode Of BOPP labels During Processing
What effect does rain have on BOPP labels? The preservation of BOPP labels becomes more difficult in rainy days, especially when it is continuously rainy. Today, we will talk about how to save BOPP labels in rainy season.
Storage of BOPP labels materials: Self-adhesive materials are easy to get damp when placed in high humidity environment, which will affect its flatness, printability and labeling effect. It causes the label to curl, drop ink, wrinkle and so on. Therefore, labels need to be stored in a dry environment to avoid adverse effects caused by high humidity. The storage environment is 22℃ 2℃, and the relative humidity is 50% 5%. The materials should not be placed in direct contact with the ground and walls.
Temperature and humidity of processing environment: The processing environment is very important for printing processing. If the humidity is too low or too high, the materials will have adverse effects on paper feeding, printing, die cutting and slitting because of the surface material and bottom. As a result, materials can not be processed and used smoothly. At the same time, the humidity is too high, which causes the paper material to get wet during processing, which will affect its printability and lead to wrinkling. Generally, the environmental requirements for self-adhesive printing are: temperature 18-25℃, relative humidity 50%-60%.
