What is the test method for the anti-scratch performance of the heat-sensitive label paper?

The anti-scratch performance test method of heat-proof label paper usually involves a series of scientific, repeatable and standardized test processes. Here are some common detection methods:

1. Scratch-resistant test equipment

Equipment selection: Use professional scratch resistance test equipment, which can apply different pressures to the scratch head through the pressure device, and match different speeds for testing.

Standardized operation: Scratch resistance of thermal paper is tested under the same scratch test material, different test speeds and different test pressures to ensure the stability and comparability of test results.

2. Visual assessment method

Direct scratching: Use a standard scratching tool (such as coins, keys and other hard objects) to scratch the surface of the label paper with a certain amount of force.

Observe marks: Carefully observe the marks left after scratching to assess the extent of damage to the label surface and printed information. The shallower the trace and the clearer the information, the better the anti-scratch performance.

3. Friction testing machine

Equipment use: The friction testing machine is used to simulate the friction conditions in actual use, and the label paper is continuously or periodically tested by friction.

Data analysis: Evaluate the scratch resistance of the label paper by measuring the gloss, color change and other parameters before and after friction. This method is more accurate and objective.

4. Third-party testing and certification

Inspection authority: Send the label paper to a qualified third-party testing institution for testing.

Authoritative report: Third-party organizations will conduct tests according to industry standards or customer requirements, and issue authoritative test reports. This helps verify that the anti-scratch properties of the label paper meet the requirements.

5. Practical application simulation

Environment simulation: Based on the actual application scenarios of labels, simulate possible scratches, such as friction during transportation and unexpected scratches during use.

Long-term observation: Long-term observation of the label paper in a simulated environment to evaluate the durability and stability of its scratch resistance.

Matters needing attention

Test standards: When conducting anti-scratch performance tests, relevant industry standards or customer requirements should be followed to ensure the accuracy and comparability of test results.

Sample selection: Representative samples should be selected for testing to avoid the deviation of test results caused by improper sample selection.

Equipment calibration: Before testing, the test equipment should be calibrated and checked to ensure the accuracy and reliability of the test results.

In summary, there are a variety of anti-scratch performance testing methods for the three heat-resistant label paper, and appropriate test methods and processes can be selected according to specific needs and conditions. These methods help to evaluate whether the anti-scratch performance of the label paper meets the requirements, so as to ensure its stability and reliability in practical applications.
