How to store A4 stickers correctly?

Proper storage of A4 adhesive labels requires consideration of multiple factors to ensure their quality and extend their lifespan. Here are some key storage recommendations:

1、 Control temperature and humidity

Temperature: Adhesive labels should be stored at room temperature, with a recommended temperature range of 21 ° C~25 ° C (or around 22 ± 2 ° C, 25 ° C), to avoid exposure to extreme temperatures. High temperatures may cause the adhesive to melt, while low temperatures may make the label fragile.

Humidity: The storage environment for adhesive labels requires a humidity of 45% to 55% (or around 50% ± 5%, 60%). Excessive or insufficient humidity may affect the adhesion effect of the labels.

2、 Avoid direct sunlight

Adhesive labels should be stored in a cool, dry place, away from direct sunlight. The ultraviolet rays in sunlight may have adverse effects on the adhesion performance and color stability of adhesive labels. If long-term storage is required, black or opaque containers can be considered to block light.

3、 Moisture prevention and packaging

Moisture proof: Adhesive labels should be kept away from damp environments to prevent moisture from causing label deterioration or adhesive failure.

Packaging: It is recommended to use plastic film to seal the packaging. After each use, the packaging should be sealed again to isolate dust, moisture, and external pollution, and to keep the labels clean and dry.

4、 Storage location and stacking method

Storage location: Avoid placing adhesive labels in places where they are under pressure or pressure changes to prevent the shape of the labels from changing or being damaged. At the same time, the label paper should not directly contact the ground or wall to prevent the adsorption of dust and moisture.

Stacking method: When stacking, moisture-proof paper or film packaging should be sealed properly. Roll packaging should be stacked upright and stored flat and level. The height of each board should not be too high (such as not exceeding 1 meter), and the goods should be at least 10 centimeters above the ground (with wooden boards) to prevent excessive weight from causing glue penetration and adhesion.

5、 First in, first out principle and regular inspection

First in, first out: In order to avoid quality issues such as discoloration and glue overflow of labels due to long-term inventory, warehouse management should strictly implement the "first in, first out" system. Regularly check inventory and prioritize using labels that were received earlier.

Regular inspection and maintenance: Regularly inspect the storage environment to ensure that the insulation and humidity control equipment is operating normally and the packaging is well sealed. At the same time, observe whether there are signs of discoloration, deformation, or adhesive failure on the label, and take timely measures to deal with them.

6、 Usage period

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.

In summary, the correct storage of A4 adhesive labels requires comprehensive consideration of multiple factors such as temperature, humidity, lighting, packaging, storage location, and stacking method. By following these storage recommendations, the quality of adhesive labels can be ensured and their lifespan can be extended.
