how to store thermal paper

Thermal paper shelf life is the time period from the production terminal sales to the market, unopened thermal paper after leaving the factory to the time period that can be used normally. Usually thermal printing paper manufacturers will be in the thermal paper packaging and sealing the last process covered with the date of production, this is the factory time, and then according to the procurement of thermal printing paper paper performance, packaging technology, upstream turnover period, etc. combined to confirm the length of the shelf life. Common thermal printing paper shelf life of 6 months - 2 years, ranging from special customization requirements of the thermal printing paper shelf life can reach 10 years.

There is a formula for calculating the shelf life hours of thermal printing paper:

• Theoretical Shelf Life = Original Mill Specified Shelf Life - (End Processor Mill Date - Original Mill Date)

The shelf life of thermal paper is affected by the entire production line process.

• First of all, good paper quality base paper quality and stability, not easily affected by the outside world to ensure the stability of the thermal coating coated on top of the base paper;
• Secondly, the amount and quality of the thermal coating material also directly affects the shelf life of the thermal printing paper and color effect;
• Third, the quality of the outer layer of the thermal printing paper protective coating makes the thermal printing paper in the storage and transportation and post-processing process plays an important role in the stability of the protection.

The shelf life of thermal paper is ideal, and the real shelf life of thermal paper will be affected byUse habits,Packaging grade,printer properties,and other factors, which makes the shelf life greatly reduced.

• Usage habits: Printing paper should be wrapped and rolled up after unpacking, and stored away from humidity, light and other environments;
• Printer Properties: Choose the appropriate printer for whether the paper will print at low or high temperatures.
• Packaging grade: common packaging paper packaging (anti-light function) transparent vacuum plastic packaging (moisture-proof function) and aluminum film vacuum packaging (put direct sunlight and moisture-proof at the same time)

This is different from the concept of the shelf life of thermal paper, which belongs to the durability of the color development effect after the use of thermal paper.

The special chemical properties of thermal printing paper make it will not be preserved as long as ordinary ribbon printing paper. Carbon is known to be very chemically stable.

Currently on the market according to the application of different thermal printing paper color rendering keep time length is as follows:

• Supermarket cash register tickets: thermal printing paper color rendering lasting time of about 6 months;
• Movie tickets: three-proof paper to make movie tickets lasting time 1 year, ordinary movie tickets 6 months;
• Small ticket paper for bag storage cabinet: 3 months;
• ATM voucher: 6 months;
• Lottery tickets: 1-2 years;
• Medical record paper: more than 2 years.
