How to evaluate the durability and endurance of small roll thermal label paper?

Evaluating the durability and endurance of small roll thermal label paper can be considered from multiple dimensions. Here are some specific evaluation methods and indicators:

1、 Physical performance testing

Thickness measurement: Use a thickness gauge to measure the thickness of the paper, ensuring its uniformity to avoid problems such as paper jams or inconsistent printing quality during the printing process. Paper with uniform thickness is more durable and less prone to damage.

Flatness test: Evaluate the flatness of the paper to ensure that there are no wrinkles or bends during the printing process, which may affect the printing effect and durability.

Tensile strength test: Use a tensile testing machine to measure the tensile strength of paper to ensure its durability during printing and use. Paper with high tensile strength is less likely to tear or break.

Tear strength test: Evaluate the tear strength of paper to ensure its integrity during use. Paper with high tear strength is more wear-resistant and less prone to tearing.

2、 Chemical performance testing

Water resistance test: Soak the paper in water and observe its deformation and fading. Paper with good water resistance can still maintain clear handwriting and paper integrity in humid environments or accidental contact with liquids.

Chemical resistance test: Wipe the colored area with chemical reagents (such as alcohol, acetic acid, etc.), observe and record the changes in the colored area. Paper with good chemical resistance will not fade or deteriorate when exposed to common chemicals.

PH value test: Measure the acidity and alkalinity of paper to ensure its safety for print heads and other devices. Paper with a suitable pH value is more stable and less prone to chemical reactions with printing equipment, thereby extending its service life.

3、 Environmental adaptability testing

Light resistance test: Evaluate the durability of thermal paper under light conditions and determine its degree of fading in sunlight. Paper with good light resistance can maintain clear handwriting even when exposed to sunlight for a long time.

Temperature resistance test: to test the stability of thermal paper in high and low temperature environments. By conducting high-temperature experiments to test its heat resistance, it is ensured that the quality will not decrease during storage and use due to high temperatures, such as avoiding severe fading when exposed to direct sunlight or near heat sources. Meanwhile, it is also necessary to test its performance in low-temperature environments to ensure its stability under various climatic conditions.

4、 Printing performance testing

Color rendering performance test: By simulating the printing process through heating, observe the reaction speed, color rendering depth, and uniformity of thermal paper. The color rendering should be fast, uniform, and free of obvious defects in dark areas, ensuring that the printed image or text is clear and visible. Paper with good color rendering performance can present better image and text effects when printed.

Wear resistance test: Evaluate the wear resistance of the coating through friction experiments to ensure that the paper will not lose or blur information due to wear during daily use. Paper with good abrasion resistance can maintain clear handwriting and paper integrity even after frequent use and friction.

5、 Long term storage performance testing

To evaluate the performance of thermal paper in different environments and conduct long-term storage performance tests. By simulating different climatic conditions such as humidity, light intensity, etc., observe whether the colored part of the thermal paper undergoes fading, discoloration, and other phenomena to ensure its suitability for various storage needs.

6、 Accelerated aging test

Simulate harsh environmental conditions using accelerated aging equipment to test the durability of thermal paper during long-term storage. This method can evaluate the durability of paper faster, in order to promptly identify problems and make improvements.

In summary, evaluating the durability and endurance of small roll thermal label paper requires comprehensive consideration of multiple factors. By conducting physical performance testing, chemical performance testing, environmental adaptability testing, printing performance testing, long-term storage performance testing, and accelerated aging testing, the durability and endurance of the paper can be comprehensively evaluated, so as to select the thermal label paper that is more suitable for one's own needs.
