How to store circular colored copperplate labels to ensure their quality?

In order to store circular colored copperplate labels and ensure their quality, a series of professional storage methods need to be followed. Here are some key storage recommendations:

1、 Temperature and humidity management

Temperature control:

It is recommended to store at a temperature of 20-25 ℃. Avoid glue overflow or label material aging caused by high temperatures (>35 ℃), and also prevent glue failure caused by low temperatures (<5 ℃).

Humidity control:

The relative humidity should be controlled between 50% and 60%. Excessive humidity can cause paper to absorb moisture and deform, ink to spread, and even glue to mold; If the humidity is too low, it may cause static electricity, adsorb dust, and affect the clarity of the label.

2、 Light avoidance and protection

Avoid light:

Long term direct sunlight can cause labels to fade, age, and even affect their adhesion. Therefore, when storing, it is necessary to ensure that the labels are not directly exposed to sunlight, and can be placed in a dark place or with blackout curtains.

Dust and moisture prevention:

The storage space should be kept clean, away from dust, oil stains, and chemical solvents (such as alcohol and cleaning agents), to prevent surface contamination of labels or corrosion of adhesives.

To prevent labels from getting damp, desiccants can be placed in the storage space to maintain a suitable humidity level.

3、 Storage methods

Flat placement:

Labels should be placed flat to avoid folding or curling, in order to prevent deformation and damage.

Regular flipping:

To prevent paper adhesion, it is recommended to regularly flip the label paper to ensure it remains flat.

Avoid heavy pressure:

For roll labels, it is necessary to prevent compression and avoid the formation of "chrysanthemum pattern" wrinkles. The stacking layers should not be too many, and it is usually recommended that the number of rolls should not exceed 5 layers to prevent the adhesive from penetrating after the lower labels are compressed.

4、 Packaging and labeling

Retain original factory packaging:

Unopened labels should be kept in their original moisture-proof packaging (such as aluminum foil bags) to extend their shelf life.

Sealed packaging:

After opening, the label should be wrapped in a sealed bag or wrapping film to prevent dust and moisture from entering.

Classified storage:

Store according to material (such as copperplate paper) and adhesive type (permanent adhesive, removable adhesive) to avoid confusion in usage scenarios.

Compliance retention:

If the stored labels are used in industries such as food, sample and batch records must be retained for traceability of printing information compliance.

5、 Regular inspection and management

Regular inspection:

Regularly inspect the quality of labels, including adhesion, color, and clarity, and promptly address any potential issues.

First in, first out principle:

For labels with a shelf life (such as adhesive labels), the "first in, first out" principle should be followed to ensure the use of the latest produced labels.

In summary, through reasonable temperature and humidity management, light avoidance and protection, correct storage methods, proper packaging and labeling, and regular inspection and management, circular colored copperplate labels can be effectively stored and their quality can be guaranteed.
