How to judge the quality of PET matte silver thermal paper?

The quality of PET matte silver thermal paper can be judged from the following aspects:

1、 Appearance inspection

Color and Gloss:

Good quality PET matte silver thermal paper should have a uniform matte silver texture, a slight greenish tint (or vary depending on specific product characteristics), and should not be too pale or reflective. Pale or highly reflective paper may have added too much fluorescent agent, affecting printing quality and shelf life.

Observe whether the surface of the paper is flat, with no obvious flaws, ripples, or bubbles.

Coating uniformity:

The coating should be evenly applied to the surface of the paper, and there should be no local thickness or thinness. The uniformity of the coating can be checked by touching the surface of the paper or using a magnifying glass for observation.

2、 Printing effect test

Clarity and Resolution:

Use a thermal printer for printing testing, observe whether the printed images and text are clear, and whether the edges are sharp. High quality PET matte silver thermal paper should be able to present high-definition and high-resolution printing effects.

Color stability:

After printing, observe whether the color is stable and not easily faded. High quality thermal paper should have a longer color retention period, and can maintain color stability even under prolonged exposure to light or high temperature environments.

3、 Durability testing

Waterproof and oil resistant performance:

Place the printed PET matte silver thermal paper in a water or oily environment and observe whether it will appear blurry, faded, or deformed. High quality paper should have good waterproof and oil resistant properties.

Wear resistance:

Use standard abrasion resistance testing equipment to conduct abrasion resistance tests on printed paper, observing whether its surface is easily scratched or worn. High quality paper should have strong abrasion resistance.

4、 Other performance tests

High temperature resistance performance:

Place the printed paper in a high-temperature environment and observe whether it undergoes deformation, fading, or color changes. High quality paper should be able to maintain stable performance within a certain range of high temperatures.

Environmental performance:

Understand the environmental performance of paper, such as whether it is made of recyclable materials and whether it contains harmful substances. High quality paper should meet environmental requirements and reduce its impact on the environment.

5、 Supplier reputation and certification

Supplier reputation:

Choose a supplier with good reputation and credibility to purchase PET matte silver thermal paper. You can understand the reputation of suppliers by reviewing their historical records, customer evaluations, and other methods.

Certification status:

Understand whether the paper has passed relevant quality and environmental certifications, such as ISO9001 quality management system certification, RoHS environmental certification, etc. These certifications can serve as an important reference for judging the quality of paper.

In summary, the quality of PET matte silver thermal paper needs to be comprehensively evaluated from multiple aspects such as appearance, printing effect, durability, other performance, and supplier reputation and certification. Through comprehensive testing and inspection, it can be ensured that high-quality PET matte silver thermal paper is selected to meet application requirements.
