What are the storage conditions for colored copper label paper?

The storage conditions of color copperplate label paper mainly involve temperature, humidity, light, packaging and stacking methods. The following is a detailed summary of these requirements:

First, temperature and humidity

Recommended storage conditions: The temperature is controlled at 22±2℃ or 23±2℃, and the relative humidity is maintained at 50%±5%. This is to maintain the stability of the label paper and extend its service life.

Actual operating range: For storage environments that cannot strictly meet the above conditions, label printing companies can control the temperature at 18-28 ° C and the humidity at 40%-60%. At the same time, fluctuations in storage temperature and humidity should be minimized to prevent paper expansion and deformation.

Second, lighting

Prevent direct sunlight: color plate label paper should avoid long-term exposure to direct sunlight, so as not to cause the paper to fade or performance decline.

Third, packaging and stacking

Outer packaging of surface materials or labels: use materials such as plastic film for packaging, and reseal after each use to prevent the impact of dust, moisture and other external factors on the paper.

Layer stacking: After the printed labels are packed, they should be stacked in layers to avoid glue penetration and adhesion caused by excessive stacking. At the same time, the stacking height should be moderate to reduce the compression of the paper self-adhesive material.

Fourth, other precautions

Material characteristics: The self-adhesive glue coating (such as water glue, hot glue, etc.) of color copperplate label paper has good viscosity, but it is still necessary to pay attention to avoid adhesion during storage.

Testing and verification: The customer shall test the label in the end-use environment to confirm that it meets the requirements of that environment.

In summary, the storage conditions of color copperplate label paper need to consider temperature, humidity, light, packaging and stacking methods. Through reasonable storage conditions, the service life of the label paper can be extended and its good performance can be maintained. At the same time, customers should conduct adequate testing before use to ensure that the label paper can meet the actual needs.
