How long is the shelf life of BOPP thermal sensitive synthetic paper?

The shelf life of BOPP thermal sensitive synthetic paper is not a fixed time, but is influenced by various factors, including paper quality, processing methods, and storage environment. The following is a detailed analysis of the shelf life and influencing factors of BOPP thermal sensitive synthetic paper:

1、 Overview of shelf life

General shelf life: The commonly used BOPP thermal synthetic paper on the market is usually labeled with a shelf life of three years or more on its packaging, but this is mainly for high-quality thermal paper.

Quality impact: The quality of paper has a crucial impact on its shelf life. High quality thermal paper can ensure high-quality printed data and extend the storage time of the data. On the contrary, low-quality thermal paper may only be stored for a shorter period of time.

2、 Influencing factors

Paper quality:

The coating quality, uniformity, and chemical composition of thermal paper directly affect its storage time. High quality coatings and reasonable chemical composition can significantly improve the shelf life of thermal paper.

The quality of thermal paper can be judged through some simple tests, such as observing the color change on the back of the paper when burned, or observing the blackening time of printed paper with the same content naturally exposed to sunlight.

Handling method:

The correct handling method can extend the storage time of thermal paper. For example, when printing, the appropriate printing temperature should be selected to avoid damage to the thermal sensitive coating caused by excessively high or low temperatures.

When storing thermal paper, it should be placed in a cool and dark place, avoiding direct sunlight and high temperature environments.

Storage environment:

The temperature, humidity, and lighting conditions of the storage environment can all affect the storage time of thermal paper. High temperature, high humidity, and direct sunlight can accelerate the aging of thermal sensitive coatings, leading to fading or disappearance of handwriting.

The ideal storage environment should be cool, dry, and away from light.

3、 Methods to extend shelf life

Choose high-quality thermal paper: When purchasing, choose thermal paper from well-known brands with guaranteed quality.

Proper handling and storage: Print and store thermal paper correctly according to the above handling method.

Adopting auxiliary protective measures: Although methods such as plastic sealing cannot permanently extend the storage time of thermal paper, they can to some extent slow down the fading speed of handwriting. However, it should be noted that non adhesive plastic film and cold mounting film should be selected for cold mounting during plastic sealing to avoid damage to the thermal sensitive coating.

In summary, the shelf life of BOPP thermal sensitive synthetic paper is not fixed, but is influenced by various factors. Therefore, when selecting, processing, and storing thermal paper, these factors should be comprehensively considered to extend its storage time and ensure print quality.
