Is there any relevant standard or specification for the long-term three proof thermal paper industry?

There are relevant standards or specifications for the long-term three proof thermal paper industry. The following is a detailed summary of the relevant standards or specifications for the long-term three proof thermal paper industry:

1、 National standards

Although there is currently no specific national standard for "long-lasting three proof thermal paper", there are universal national standards in the thermal paper industry, such as GB/T 28210-2011 "Thermal Paper". This standard specifies the technical requirements, test methods, inspection rules, labeling, packaging, transportation, storage, and other contents of thermal paper, providing fundamental guidance for the production and testing of long-lasting three proof thermal paper.

2、 Enterprise standards

Some manufacturers of long-lasting three proof thermal paper will establish their own corporate standards to ensure the quality and performance of their products. These enterprise standards typically cover product classification, technical requirements, testing methods, inspection rules, as well as aspects such as labeling, packaging, transportation, and storage. For example, some companies may develop specific technical indicators for long-lasting three proof thermal paper, such as waterproof performance, oil resistance, light resistance, heat resistance, etc., and specify corresponding testing methods and judgment standards.

3、 Industry standards

In addition to national and enterprise standards, there may also be some industry norms or consensus in the long-term three proof thermal paper industry, which may be jointly developed by industry associations, research institutions, or major production enterprises. These norms or consensus can help promote technological progress and product quality improvement in the industry, and promote the healthy development of the market.

4、 Specific technical requirements

For long-lasting three proof thermal paper, its technical requirements usually include the following aspects:

Appearance quality: The paper surface should be flat, smooth, clean, and evenly coated, without wrinkles, folds, holes, obvious streaks, cracks, spots, or other appearance paper defects. The cutting edge should be neat, and the cross-section of the drum should be flat and smooth.

Dimensional deviation: The length and width dimensional deviation of label paper should be controlled within a certain range to ensure accurate adaptation on various printer devices.

Performance requirements:

Waterproof performance: After the label paper is completely immersed in water, the printed information should not fade or the fading rate should be controlled within a certain range.

Oil resistance performance: After applying edible oil to the surface of label paper, the printed information should not fade or the fading rate should be controlled within a certain range.

Weather resistance: Label paper should remain stable in different temperature and humidity environments, and printed information should not fade or deform.

Adhesive performance: Label paper should have good initial adhesion, holding strength, and peel strength to ensure that the label can be firmly attached to the surface of the object and easily peeled off.

Other properties such as friction resistance and flexibility should also meet the corresponding requirements.

5、 Testing standards

In order to evaluate the performance and quality of long-lasting three proof thermal paper, a series of testing standards and methods are usually used. These standards and methods may include densitometer measurement, colorimeter measurement, tensile testing machine testing, friction testing machine testing, etc., to comprehensively evaluate the waterproof performance, oil resistance, weather resistance, adhesive performance, and other properties of label paper.

In summary, there are relevant standards or specifications in the long-term three proof thermal paper industry, which provide a basis and guidance for the production and testing of products. Meanwhile, with the continuous advancement of technology and the continuous development of the market, these standards or specifications will also be constantly improved and updated.
