In the previous article, Leadtra Packaging compiled a list of common quality issues with sealing liners. Today, we will continue to look at key preventive measures and quick troubleshooting processes. 

1、 Key preventive measures 

Strict process control: Ensure that the heat sealing temperature, pressure, and time match the material, and regularly calibrate the equipment. 

Strengthen incoming material inspection: Conduct trial sealing on new batches of sealing liners, check the flatness of edges and the uniformity of aluminum layer residue. 

Keep the bottle mouth clean: Wipe the bottle mouth with an alcohol swab and blow dry to avoid hand contamination. 

Optimize design matching: Ensure that the sealing liner size, material, and bottle mouth are compatible to avoid uneven clamping force. 

Regular testing: Use equipment such as heat sealing strength tester to quantitatively test and adjust the process in a timely manner. 

2、Quick troubleshooting process 

Appearance inspection: Check for defects such as burnt heads and bubbles in the seal. 

Sealing test: Check whether the heat sealing strength and breaking force are within the standard range. 

Environmental simulation: Conduct high and low temperature cycling or vibration tests to observe long-term sealing performance. 

Root cause analysis: If the problem persists, check the compatibility between the sealing liner material and the contents.
