O testador de encolhimento térmico é muito importante na aplicação de filme retrátil de embalagens. 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 items. No entanto, since the shrinkage properties of shrink films are affected by a variety of factors, como temperatura, tempo, umidade, and pressure, eles precisam ser testados usando um testador de contração térmica para avaliar seu desempenho e qualidade.

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

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

Shrinkage onset temperature test: This test can test the minimum temperature at which the shrinkage film begins to shrink to evaluate its shrinkage performance and applicability.

Shrinkage balance time test: This test can test the time it takes for the shrinkage film to reach the equilibrium state to evaluate its shrinkage performance and use effect.

Contraction force test: This test can test the contraction force of the contraction film during contraction to evaluate its applicability and quality.

Através desses testes, the performance and quality of packaging shrink film can be comprehensively evaluated and its suitability for specific packaging areas can be determined. Além disso, o testador de encolhimento térmico também pode ser usado para controle de qualidade e inspeção, manufacturers can use this equipment to test the shrinkage performance and quality of each batch of packaging shrinkage film to ensure that its quality meets the requirements of the standard.
