Meaning of testing

In summary, the sealing strength of packaging heat seals has an important impact on the preservation, safety, appearance, sales value, and efficiency of the production and transportation process of the product. It is a key link to ensure product quality and user satisfaction.

How to test

The sealing strength of cookie packaging heat seal refers to the sealing performance of cookie packaging bags at the sealing point, and the testing method usually includes the following steps:
Sample Preparation: Some cookie bags are randomly selected from the production line as samples to ensure they are representative.
Preparation of test equipment: A heat sealing strength tester is needed, which can simulate the sealing strength under actual use conditions by heating the sealing area and applying a certain pressure.
Sample sealing: Seal the selected sample cookie bags according to the normal sealing method to ensure that the sealing quality meets the production requirements.
Test Parameter Setting: Set the parameters of the tester, including temperature, time and pressure. These parameters should be compatible with the actual use conditions.
Conduct the test: Put the sealed cookie bags into the heat sealing strength tester and conduct the test according to the set parameters. The instrument will heat the seal and apply pressure to check the strength of the seal.
Record test results: Record data such as the pressure applied during the test and the time of the test, and record the sealing condition of the cookie packaging bag, such as whether there is any air leakage or powder leakage.
Analyze the results: Analyze the test results to assess whether the heat sealing strength of the cookie packaging bags meets the requirements. Differences between samples can be compared, or the test results can be compared with standards.
In addition, there are some other methods that may be used to test the sealing strength of cookie packaging heat seals, such as anti-tension test and air tightness test. The specific choice of which test method to use should be decided according to the specific situation and needs.
