What are the storage requirements for copperplate adhesive labels?

The storage conditions for copperplate adhesive labels are as follows:

1、 Temperature and humidity control

Best storage conditions: temperature of 23 ℃, humidity of 50%. In this environment, adhesive materials can be stored for one year. After more than one year, it is necessary to check the adhesive and peel properties of the paper surface material.

Actual storage environment: Label printing companies may find it difficult to achieve the optimal conditions mentioned above, but they should try to control the ambient temperature at 1828 ℃ and humidity at 40% -60%. At the same time, efforts should be made to ensure minimal fluctuations in storage temperature and humidity to prevent paper swelling, deformation, and other issues.

2、 Avoid physical damage

Stacking strength: If paper adhesive materials are stored in whole rolls, the stacking strength should not be too high, and the stacking height should be moderate to prevent the material from being deformed or damaged under pressure.

Avoid direct sunlight: Ultraviolet rays in sunlight may have adverse effects on the adhesion performance and color stability of adhesive labels. Therefore, labels should be stored in a cool and dry place, avoiding direct sunlight.

3、 Prevent chemical reactions

Avoid contact with chemicals: Some chemicals may react with the adhesive on the sticker, causing a decrease in its stickiness or deformation of the label. Therefore, when storing, it is advisable to avoid exposing adhesive labels to chemicals such as solvents, acids, and bases.

4、 Other precautions

Shelf life: Adhesive labels usually have a shelf life, beyond which problems such as color fading and decreased adhesion may occur. Therefore, before using adhesive labels, their expiration date should be checked and fresh labels should be used as much as possible.

Fire safety: Many surface materials and adhesives of adhesive materials are flammable, so it is advisable not to stack the materials too densely in the warehouse and ensure smooth safety passages.

In summary, in order to ensure the quality and performance of copperplate adhesive labels, temperature and humidity should be strictly controlled during storage, physical damage and chemical reactions should be avoided, and attention should be paid to shelf life and fire safety.
