Heat shrinkage tester is also very important in the application of flexible packaging composite film. Flexible packaging composite film is a kind of commonly used packaging material, which is characterized by excellent water, gas, oil resistance and mechanical strength, suitable for various packaging fields, such as food, medicine, daily chemical and so on. However, since the properties of composite films are affected by a variety of factors, such as temperature, pressure, and humidity, they need to be tested using a heat shrinkage tester to evaluate their performance and quality.

In the application of flexible packaging composite film, the heat shrinkage tester can perform the following tests:

Thermal shrinkage test: This test can test the shrinkage of composite films under certain temperature and time conditions to evaluate their thermal shrinkage performance and applicability.

Heat shrinkage starting temperature test: This test can test the minimum temperature at which the composite film starts heat shrinkage to evaluate its heat shrinkage performance and applicability.

Heat shrinkage balance time test: This test can test the time required for the composite film to reach the equilibrium state to evaluate its heat shrinkage performance and use effect.

Thermal shrinkage test: This test can test the shrinkage force of composite films during thermal shrinkage to evaluate their applicability and quality.

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

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