Ang heat shrink tester ay napakahalaga rin sa application ng flexible packaging composite film. Flexible packaging composite film is a commonly used packaging material, which is characterized by excellent water, gas, oil resistance and mechanical strength, suitable for various packaging fields, such as food, gamot na, daily chemical, atbp. Gayunpaman, since the properties of composite films are affected by many factors, tulad ng temperatura, pressure and humidity, it is necessary to use a heat shrink tester to test them to evaluate their performance and quality.

In the application of flexible packaging composite film, the heat shrink tester can carry out the following tests:

Thermal shrinkage test: This test can test the shrinkage rate of composite film under certain temperature and time conditions to evaluate its thermal shrinkage performance and suitability.

Thermal shrinkage initial temperature test: This test can test the minimum temperature at which the composite membrane begins to thermal shrink to assess its thermal shrinkage performance and suitability.

Thermal shrinkage equilibrium time test: This test can test the time required for the composite membrane to reach equilibrium state, in order to evaluate its thermal shrinkage performance and use effect.

Thermal shrinkage force test: This test can test the shrinkage force of the composite membrane during the thermal shrinkage process to assess its suitability and quality.

Sa pamamagitan ng mga pagsubok na ito, the performance and quality of the flexible packaging composite film can be comprehensively evaluated, and whether it is suitable for a specific packaging field. Bukod pa rito, the thermal shrinkage tester can also be used for quality control and inspection. Manufacturers can use the equipment to test the thermal shrinkage performance and quality of each batch of flexible packaging composite film to ensure that its quality meets the standard requirements.

In conclusion, the thermal shrinkage tester is of great significance in the application of flexible packaging composite film, which can help manufacturers to evaluate the thermal shrinkage performance, applicability and quality of composite film, to ensure that it can effectively wrap and protect the packaged goods.
