Plastic bags are a common packaging material, widely used in the packaging and transportation of various commodities. Since plastic bags are used in different environments, such as high temperature or low temperature environments, high-low temperature resistance tests are required to test the physical and chemical properties of plastic bags at different temperatures, such as tensile strength, heat resistance, impact resistance , anti-aging properties, etc. This kind of test can detect the durability and stability of plastic bags, so as to ensure that the plastic bags will not be broken, deformed, aged and other problems due to changes in the external environment during long-term use, and ensure the integrity of the packaging and the safety of the product. At the same time, the high-low temperature resistance test can also test the chemical properties of plastic bags, such as acid and alkali resistance, oil resistance, etc., so as to ensure that plastic bags can be used in different material environments and improve their practical value and scope of application.
The high-low Temperature Test Chamber is used to test the performance and stability of plastic bags in high-low temperature environments to evaluate their scope of application and service life. This type of test can simulate the use of plastic bags at different ambient temperatures to determine whether they meet the requirements for use.
experiment procedure
(1) Place the plastic bag to be tested in the high-low Temperature Test Chamber, and adjust the temperature of the Test Chamber to the set high temperature value (eg 60°C).
(2) Keep the temperature stable for a period of time (such as 24 hours), and then adjust the temperature of the Test Chamber to the set low temperature value (such as -20°C).
(3) Keep the temperature stable for a period of time (for example, 24 hours), and then adjust the temperature of the Test Chamber back to the set high temperature value.
(4) Repeat the above process several times to test the performance and stability of the plastic bag under alternating high-low temperature environments.
(5) During the test, the parameters of the plastic bag can be monitored and recorded, such as temperature, deformation, etc.
(6) After the test is completed, evaluate the performance parameters and stability of the plastic bag to determine whether it meets the requirements for use.
NBCHAO reminds you: the high-low temperature test parameters and test standards for different types of plastic bags may be different, and the specific test steps should be adjusted according to the product type and relevant standards. At the same time, sufficient safety measures need to be taken before the test to ensure that no safety accidents will occur during the test.
