How long are the three thermally sensitive paper characters retained? Do you understand the conditions for effective preservation?

Thermal paper is also known as thermal fax paper, thermal recording paper, thermal copy paper, thermal paper is a kind of processing paper, its manufacturing principle is to apply a layer of high-quality raw paper "thermal coating" (thermal discoloration layer). Our common lottery is the use of thermal paper materials, then, three heat-proof paper characters retained for how long? Here's an answer for you.

General thermal paper is only used to occasionally transmit or produce information that does not take long to store. The preservation of thermal paper has a great relationship with the environment of thermal paper preservation. If you put it under the sun and the temperature exceeds 30 degrees Celsius, you can only store it for about ten days, so the shelf life of thermal paper stored at different ambient temperatures is different.

General thermal paper preservation period is only 2 to 3 years, or even only a few months. Long-lasting thermal paper belongs to long-acting thermal paper, the current well-preserved thermal paper in the normal preservation environment (avoid high temperature and humidity, direct sunlight, avoid contact with solvents, plasticizers, etc.) up to 10 years.

Three anti-thermal paper relative to single thermal paper preservation time will be much longer, single anti-thermal paper general preservation time in six months to half a month or so, but three anti-thermal paper due to its own property problems, preservation time of up to a year, or even 2-3 years.

The difference between three heat-proof paper and single heat-proof paper:

Single defense: waterproof.

Three anti-: waterproof, anti-oil, anti-wear.

1. Single thermal paper labels, generally are the use of ordinary materials, white surface, clear printing, can be simple waterproof, basically can meet the general retail, bar code printing, logistics and transportation and other fields of use requirements, and cheap.

2. Three anti-thermal label, using special surface material, with three anti-function (waterproof anti-oil anti-pvv).

3. Three heat-proof paper is the use of hot melt glue, the initial viscosity is better, can be applied to some surface is not very flat labeling base surface;

At present, the market of thermal paper is uneven, the country has not yet issued a national standard, many users also do not know how to identify the quality of thermal paper, which for many businesses to maintain poor quality thermal paper to provide a convenient, for users to cause losses, light storage time is shorter, blurred handwriting, heavy damage to the printer. Thermal printing paper is generally divided into three layers, the bottom layer is the paper base, the second layer is thermal coating, the third layer is the protective layer, mainly affecting its quality for the thermal coating or protective layer.

How to identify thermal paper materials:

1. Appearance: If the paper is very white, the paper's protective coating and thermal coating is unreasonable, added too much phosphor, better paper should be slightly green. Paper finish is not high or looks uneven, indicating that the paper coating is not uniform, if the paper looks reflected very strong light, but also added too much phosphor, the quality is not very good.

2. Fire roasting: the method of roasting with fire is also very simple, with a lighter on the back of the paper heating, if heated, the color of the paper is brown, indicating that the thermal formula is not reasonable, the preservation time may be relatively short, if the black part of the paper has small stripes or uneven color blocks, indicating that the coating is uneven. Better quality paper should be black-green (with a little green) after heating, and the color blocks are uniform, the color gradually fades from the center to the four.

3. Contrast identification of sunlight: the printed paper is applied with a highlighter and placed in the sun (this can speed up the thermal coating response to light), which paper is the fastest blackening, indicating that the shorter the time to save.
