What is the shelf life of three proof thermal paper?

The shelf life of three proof thermal paper is affected by various factors, including production quality, storage environment, and usage conditions. Normally, the shelf life of three proof thermal paper is longer than that of ordinary thermal paper. The following is a specific analysis:

1、 General shelf life range

Under normal circumstances, the three proof thermal paper can be stored for about 2 years due to its waterproof, oil proof, and alcohol proof properties. If high-quality domestic paper specific fabrics are used, the storage time may be longer.

High quality products: Some high-quality three proof thermal paper, under good storage conditions, can even maintain its printed content for 3 years without fading, and some can even reach a shelf life of 10 years.

2、 Factors affecting shelf life

Storage environment: Storage conditions such as temperature, humidity, and light can affect the shelf life of three proof thermal paper. Adverse environments such as high temperature, high humidity, and direct sunlight can accelerate the aging of thermal sensitive coatings, thereby reducing the shelf life of paper.

Usage conditions: If the three proof thermal paper is subjected to excessive friction, scratching, or contact with harmful solvents during use, it will also affect its shelf life.

Production quality: The selection of raw materials and process control during the production process can also affect the shelf life of the three proof thermal paper. High quality raw materials and advanced production processes can extend the shelf life of paper.

3、 How to extend shelf life

Choose a suitable storage environment: Storing the three proof thermal paper in a cool, dry, and dark environment can effectively extend its shelf life.

Avoid contact with harmful substances: During use, avoid the three proof thermal paper from coming into contact with harmful solvents, plasticizers, and other substances to reduce damage to the paper.

Reasonable use and storage: When using three proof thermal paper, try to minimize friction and scratching, and store it properly to avoid damage.

In summary, the shelf life of three proof thermal paper is generally around 2 years, but the specific shelf life may be affected by various factors. To ensure the shelf life of paper, it is recommended to choose a suitable storage environment, avoid contact with harmful substances, and use and store the three proof thermal paper reasonably.
