Heat shrink tester is very important in the application of packaging shrink film. Packaging shrink film is a kind of packaging material widely used in various packaging fields, which is characterized by good plasticity and shrinkage performance, and can effectively wrap and protect the packaged goods. However, because the shrinkage performance of shrink film is affected by many factors, such as temperature, time, humidity and pressure, it is necessary to use a heat shrink tester to test it to evaluate its performance and quality.

In the application of packaging shrink film, the heat shrink tester can perform the following tests:

Shrinkage test: This test can test the shrinkage rate of shrink film under certain temperature, time and humidity conditions to evaluate its shrinkage performance.

Shrinkage initiation temperature test: This test tests the minimum temperature at which the shrink film begins to shrink in order to assess its shrinkage performance and suitability.

Shrinkage balance time test: This test can test the time required for the shrinkage film to reach the equilibrium state, in order to evaluate its shrinkage performance and use effect.

Shrinkage force test: This test tests the shrinkage force of the shrink film during shrinkage to assess its suitability and quality.

Application of heat shrink tester in packaging shrink film

Through these tests, the performance and quality of packaging shrink film can be comprehensively evaluated, and its suitability for specific packaging areas can be determined. In addition, the heat shrink tester can also be used for quality control and inspection, manufacturers can use the equipment to test the shrinkage performance and quality of each batch of packaging shrink film, to ensure that its quality meets the standard requirements.

In short, the heat shrink tester is of great significance in the application of shrinker film, which can help manufacturers to evaluate the shrinker film shrinkage performance, applicability and quality, to ensure that it can effectively wrap and protect the packaged goods.
