Bag Seal Integrity Tester | Vacuum Leak Test

PRODUCT DETAILS

The Bag Seal Integrity Tester is designed to detect leaks and sealing defects in bags and packages using a vacuum-assisted immersion method. The sample is placed in the water-filled test chamber and exposed to high vacuum. If a leak is present, air escapes from the package and forms visible bubbles in the water, allowing the operator to identify weak seals, welding defects or other leakage points quickly.

Description

What Is a Bag Seal Integrity Tester?

The Bag Seal Integrity Tester is a laboratory device used to identify leaks and sealing defects in flexible bags and packages.

The system uses a vacuum-assisted water immersion method. The package sample is placed inside a water-filled chamber and then exposed to vacuum.

If the package contains a leak, the air inside the package expands and escapes through the defective area. The escaping air forms visible bubbles in the water.

This allows the operator to identify the presence and approximate location of the leakage point.

Vacuum Leak Test Principle

During the test, the sample is completely positioned inside the test chamber.

The vacuum system then reduces the pressure around the package. As the external pressure decreases, the air trapped inside the package expands.

If there is a weak seam, pinhole, welding defect or other leakage path, air escapes through that point and produces bubbles in the surrounding water.

The operator can therefore perform a direct visual assessment without complicated measuring procedures.

Package Seal Inspection

The tester can support inspection of different package areas such as:

heat-sealed sections
welded areas
seams
closures
package surfaces
possible pinholes
weak sealing points

This makes the system practical for routine packaging quality control.

Quality Control Applications

Vacuum leak testing can be used during:

packaging production
laboratory quality control
package development
seal verification
routine sample inspection
manufacturing process checks

The visual test principle helps operators detect defective packages quickly.

LT-G0091 Technical Structure

The LT-G0091 Bag Seal Integrity Tester has overall dimensions of 60 × 60 × 80 cm.

The approximate weight of the device is 50 kg.

Its chamber-based construction allows the sample to be observed directly during the vacuum test.

Practical Visual Leak Detection

One of the main advantages of the system is its straightforward inspection method.

The operator does not need to interpret complex electronic data. Instead, leakage is indicated by visible air bubbles appearing from the package while it is under vacuum.

This provides a simple and practical method for checking package integrity.

Laboratory and Packaging Applications

The system can be used for suitable bags, pouches and packaged samples where vacuum leak inspection is required.

The exact testing conditions should be selected according to the package type, material and internal laboratory procedure.

Overall, the Bag Seal Integrity Tester provides a practical solution for identifying leakage points in packaged products through a vacuum-assisted visual bubble test.
