How to judge whether BOPP color thermal synthetic paper meets the quality standard?

To determine whether BOPP color thermal synthetic paper meets the quality standard, it can be considered from the following aspects:

First, appearance inspection

1.Color uniformity: Observe whether the surface color of the paper is uniform, and there is no obvious color difference or spots. High quality BOPP color thermal synthetic paper should have an even and consistent color.

2.Finish: Check the surface finish of the paper and avoid choosing a paper that is too smooth or rough. Too smooth paper may not coat evenly, and too rough paper may affect the printing effect.

3.Coating condition: Determine whether the paper coating is uniform by the appearance. Paper with uneven coating may have problems during use, such as poor printing effect or easy to fade.

Second, physical performance test

1.Thickness and size deviation: According to the relevant standards (such as GB/T 10003-2008, etc.), measure the thickness and size deviation of the paper to ensure that it is within the allowable range.

2.Tensile strength and elongation at break: These indicators reflect the mechanical properties of the paper. High-quality BOPP color thermal synthetic paper should have high tensile strength and appropriate elongation at break to ensure that it is not easy to break during use.

3.Heat resistance, cold resistance: Test the stability of the paper at different temperatures to ensure that it can maintain good performance within a certain temperature range.

4.Oil resistance, chemical resistance: For situations where you may come into contact with grease or chemicals, you need to test the oil resistance and chemical resistance of the paper to ensure that it will not be damaged by contact with these substances.

Third, thermal performance test

1.Color stability: Observe the color rendering effect of the writing after printing to ensure that it remains stable for a certain period of time and is not easy to fade. The color stability can be evaluated by accelerated aging test and other methods.

2.Print clarity: Use the printer to print text or patterns on the paper, and observe whether the printing effect is clear and whether the edges are neat. High quality BOPP color thermal synthetic paper should be able to provide clear printing results.

Fourth, other performance tests

1.Gloss: Test the gloss of the paper according to the specific needs to ensure that it meets the requirements of use.

2.Moisture permeability: For occasions where moisture is required, the moisture permeability of the paper can be tested to ensure that it can resist moisture erosion.

Fifth, reference standards and certification

1.Implementation standards: Check whether the BOPP color thermal synthetic paper meets the relevant national or industry standards (such as GB/T 10003-2008, T/QGCML 2791-2023, etc.), which have detailed provisions on the indicators of the paper.

2.Third party certification: Find out if the paper has been certified by a third party organization, such as ISO certification. These certifications usually mean that the paper has reached a high level in terms of quality, environmental protection, etc.

To sum up, judging whether BOPP color thermal synthetic paper meets the quality standard needs to be comprehensively considered from many aspects. In practice, detailed testing and evaluation can be carried out according to specific needs and standard requirements.
