GB/T 15171 Test Method for Sealing Performance of Soft Packaging Bags, to ensure the compliance of test data.

3、 Main product introduction

1. Negative pressure sealing tester (such as LT-02P):

Application scope: Suitable for testing the sealing performance of various packaging materials such as food bags, drug 

packaging, medical device packaging, etc.

Working principle: By applying negative pressure, observe whether there is any leakage in the packaging, and evaluate 

its sealing performance.

Features: Easy to operate, accurate and reliable test data, in compliance with multiple industry standards.

2. Vacuum attenuation method sealing tester (such as LT-02M):

Application scope: Suitable for micro leak detection of pharmaceutical packaging such as penicillin bottles, pre filled

 needles, and vials, as well as food packaging such as bagged, canned, and bottled.

Working principle: Using the principle of vacuum attenuation method, the sealing performance of the packaging is 

determined by monitoring the changes in gas pressure inside the packaging.

Features: Non destructive testing, suitable for trace leak detection, with accurate and reliable detection results.

3. Packaging leakage detector (positive pressure testing principle, such as LT-03A):

Application scope: Widely used for leak detection of various packaging materials, ensuring the sealing of products during

 production, transportation, and storage.

Working principle: By injecting gas into the interior of the sample and applying a certain pressure, observe whether there 

is any leakage in the packaging to determine its sealing performance.

Features: Easy to operate, high detection efficiency, able to promptly detect and solve packaging leakage problems.
