What are the quality standards in the long-acting heat-sensitive label industry?

The quality standard in the thermal label industry is a comprehensive system that covers multiple aspects of performance requirements and test methods. The following is a summary of the quality standards of long-acting thermal label paper based on industry standards and relevant reference articles:

First, product classification

Long-acting thermosensitive label paper is usually classified according to product material, such as ordinary thermosensitive paper and synthetic thermosensitive paper. Different types of paper may vary in performance, but they all need to meet the corresponding quality standards.

Second,Technical requirements

1.Physical property

Quantitative and quantitative deviation: Specify the quantitative range of paper and its deviation to ensure the consistency of the thickness of the paper.

Tightness: reflects the density of the paper, affecting the strength of the paper and printing effect.

Brightness (whiteness) : The brightness or whiteness of the surface of the paper, which affects the clarity of the printed image.

Smoothness: The smoothness of the surface of the paper affects the print quality and the adhesion of the ink.

Tensile strength: The ability of the paper to resist tensile breakage, ensuring the durability of the paper during use.

Tear: The ability of paper to resist tearing is also an important indicator of paper durability.

2.Chemistry and durability

Water resistance: The ability of the paper to maintain a clear and complete image after contact with water.

Oil resistance: The ability of the paper to resist oil erosion, ensuring that the printed image does not fade or blur after contact with oil.

Light resistance: The ability of paper to maintain image stability in light conditions.

Heat resistance: The ability of paper to maintain a clear and complete image at high temperatures.

Moisture resistance: The ability of paper to maintain image stability in wet environments.

3.printability

Hair color performance: including static hair color performance and dynamic hair color performance, reflecting the color performance of the paper in the printing process.

Color sensitivity: the speed and clarity of the paper's response to the printing heat source.

Image preservation performance: The length of time the image remains clear and complete after paper printing.

4.Appearance quality

The surface of the paper should be smooth, clean, evenly coated, without wrinkles, wrinkles, holes, obvious streaks, cracks and other appearance defects.

The cutting edge should be neat, and the roll section should be smooth and smooth.

The length or number of labels should be indicated on the package, and the deviation should not exceed the specified range when marking the length, and the deviation when marking the number of sheets should also be controlled within a reasonable range.

Third,Test methods

The quality inspection of long-acting thermal label paper usually involves a variety of test methods, including but not limited to:

Reflection colorimeter measurement: used to measure the color parameters of the paper, compare the measured value with the standard value.

Needle test, scratch test: evaluate the mechanical strength of the paper, such as puncture resistance, scratch resistance, tear resistance, etc.

Thermal aging test, wet thermal aging test, ultraviolet aging test: simulate the service life and stability of paper in different environments to evaluate its durability.

According to the relevant national standards (such as GB/T series standards) : size, quantitative, brightness, smoothness, tensile strength, tear and other physical properties measurement.

Fourth,Industry standards and norms

The industry standards of long-lasting heat-sensitive labels may vary from region to region and country to country, but usually refer to international general standards or national mandatory standards. For example, GB/T 28210-2011 "Thermal paper" is one of the national standards of China, which specifies the performance requirements and test methods of thermal paper in detail. In addition, there are relevant standards formulated by ASTM, ISO and other international standards organizations for reference.

Fifth,Conclusion

The quality standard of long-lasting heat-resistant label paper is a comprehensive system, covering many aspects such as physical properties, chemical and durability properties, printing performance, and appearance quality. In order to ensure that product quality meets the requirements of use, production enterprises should strictly follow the relevant standards for production and testing. At the same time, the user should also pay attention to the product quality standards and testing reports and other information to ensure that the purchase of high-quality products.
