O testador de encolhimento térmico também é muito importante na aplicação de filme composto de embalagem flexível. Flexible packaging composite film is a commonly used packaging material, que é caracterizado por excelente água, gás, resistência ao óleo e resistência mecânica, adequado para vários campos de embalagem, como comida, medicamento, daily chemical, etc.. No entanto, since the properties of composite films are affected by many factors, como temperatura, pressure and humidity, it is necessary to use a heat shrink tester to test them to evaluate their performance and quality.

Na aplicação de filme composto de embalagem flexível, the heat shrink tester can carry out the following tests:

Teste de encolhimento térmico: 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.

O testador de encolhimento térmico é usado para testar o encolhimento térmico de filme composto de embalagem flexível

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.

Através desses testes, the performance and quality of the flexible packaging composite film can be comprehensively evaluated, and whether it is suitable for a specific packaging field. Além disso, 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.

Para concluir, o testador de encolhimento térmico é de grande importância na aplicação de filme composto de embalagem flexível, which can help manufacturers to evaluate the thermal shrinkage performance, aplicabilidade e qualidade do filme composto, to ensure that it can effectively wrap and protect the packaged goods.
