What is the shelf life of A4 stickers?

The shelf life of A4 stickers is usually 1-3 years, but the specific time depends on various factors such as storage conditions, materials, and manufacturing processes. The following is a detailed analysis of the shelf life of A4 stickers:

1、 The impact of storage conditions on shelf life

Temperature and humidity: The ideal storage environment is a temperature controlled between 22-23 ± 2 ℃ and a relative humidity of 50 ± 5% or 50%+5%. Under such conditions, stickers can maintain optimal adhesion and printing effect.

Environment type: Adhesive stickers should be stored in a dry, cool, ventilated place, away from direct sunlight, high temperature, humidity, and corrosive gases. These adverse environments may cause the adhesive of the stickers to weaken, deteriorate, or be damaged.

2、 The impact of materials and manufacturing processes on shelf life

Ordinary materials such as copperplate paper, special gloss paper, and writing paper usually have a longer shelf life under appropriate storage conditions.

Special materials such as Xiao Yinlong and Transparent Dragon series, due to their high adhesive viscosity standards, have a relatively easy shelf life to reach the ideal period, but also require relatively high storage conditions.

3、 Other precautions

Usage cycle: Although ordering more adhesive labels at once may be more cost-effective, long-term storage may affect their printing quality and bonding performance. Therefore, it is recommended to purchase according to a certain usage cycle and avoid storing for too long before use.

Inspection and testing: During storage and use, the adhesion and printing effect of the adhesive should be regularly checked. If viscosity decreases or printing becomes blurry, new adhesive labels should be replaced in a timely manner.

In summary, the shelf life of A4 stickers is not fixed, but is influenced by various factors. To ensure its performance and effectiveness, relevant regulations and precautions should be strictly followed during storage and use.
