The Leakage Tester GB-M is a leak detection and seal integrity testing instrument for flexible packaging. It is designed to help manufacturers verify the quality of package sealing before products are released for use. Utilizing a vacuum testing system combined with a high-precision pressure sensor, the instrument can accurately evaluate seal performance and detect package leakage. 

The instrument is controlled by a microcomputer-based system that allows users to set the desired vacuum level and testing duration. It is ideal for Quality Control (QC), Research and Development (R&D), and packaging compliance testing in the food, beverage, pharmaceutical, and cosmetic industries. 

Working Principle of Leakage Tester GB-M 

The instrument creates a vacuum environment inside the test chamber, where the sample is submerged in water. When a pressure difference is generated between the inside and outside of the package, any leakage can be identified by observing air bubbles escaping from the package or water penetrating into it. 

If air leakage or water ingress is detected, it indicates that the package has sealing defects or leakage points. This enables manufacturers to identify packaging issues and improve production quality effectively. 

Applications 

The Leakage Tester GB-M is suitable for leak testing and package integrity evaluation of various packaging types, including: 

• Foil pouches 

• Heat-sealed plastic bags 

• Food and beverage pouches 

• Pharmaceutical and medical packaging 

• Plastic-coated paper cartons and bags 

• Plastic bottles 

• Plastic tubes 

• Cans and various rigid containers
