The sealing inspection of aluminum foil sealing gaskets can be carried out through various methods to ensure the integrity and safety of the packaging. 

Firstly, visual inspection is the most fundamental step. Observe whether the aluminum foil gasket is damaged, wrinkled, or has bubbles, especially whether the edge in contact with the container is tightly adhered. If the gasket has curled edges or is loose, it may indicate poor sealing. In addition, check whether the heat sealing adhesive is evenly distributed to avoid dry cracking or missing situations.

For more specific testing, physical methods can be used. For example, when conducting a peel test, slowly tear open the aluminum foil gasket with hands or tools. Good sealing usually requires a certain amount of force, and even adhesive residue can be seen after tearing. If the gasket easily peels off, it indicates that there may be a problem with the sealing. Another non-destructive method is press testing, gently squeezing the container to observe if the aluminum foil bulges or leaks, or flipping the container upside down and placing it in water to check for any bubbles emerging.

If more accurate detection is needed, professional instruments can be used. The sealing tester can quantitatively analyze the sealing strength by vacuuming or pressurization, while the dye penetration method can apply dye to the sealing edge to observe whether it has penetrated into the interior. The airtightness detector is suitable for high demand scenarios, detecting small leaks by filling with inert gas.

The setting of heat sealing parameters is crucial in the production process. The temperature, pressure, and time must meet the material requirements, otherwise it may result in poor sealing. The heat sealing strength tester can measure peel strength to ensure compliance with industry standards.

Finally, in practical applications, environmental factors and the characteristics of packaging contents also need to be considered. For example, food and drug packaging require aseptic testing methods, while batch production should use sampling inspection combined with destructive and non-destructive testing. If poor sealing is found, it is necessary to investigate issues such as heat sealing process, material quality, or container cleanliness, and make adjustments and optimizations.
