Sealing Testing for Glass Bottle Packaging

Product catalog summary

Introduction
Glass bottle packaging is highly favored by food and beverage enterprises due to its transparency, sealing performance, and cost-effectiveness. Ensuring the sealing performance of glass containers is crucial for manufacturers and consumers. Labthink introduces the C660B Leak and Seal Strength Tester for evaluating the sealing of glass containers.

Testing Procedure

Fill the vacuum chamber with distilled water and immerse the sample, ensuring a minimum distance of 25mm from the water surface. Multiple specimens can be tested simultaneously.
Seal the vacuum chamber, adjust the vacuum to a specified degree (20, 30, 60, 90 kPa), and maintain it for 30 seconds. The vacuum level is chosen based on specimen characteristics or product standards.
Visually inspect for gas escape to assess sealing performance. Leakage is determined by observing five successive bubbles; isolated bubbles are not considered leakage.
Release the vacuum, remove the specimen, and check for water infiltration. The C660B automatically refills the gas post-test.

Instrument Features
The Labthink C660B Tester is versatile, testing not only glass containers but also plastic bags, bottles, tubes, cans, and boxes. It is recognized for its stable and reliable quality, with key pneumatic components imported for performance reliability. The instrument meets various national test standards and simplifies operation by automatically refilling the vacuum tank.

Sealing Testing for Glass Bottle Packaging-1

Sealing Testing for Glass Bottle Packaging Because of its high transparency, good sealing performance and characteristics such as no pollution and low cost, glass bottle packaging is favored by food enterprises, especially canned production enterprises and beverage production enterprises. In general, the glass bottles for food and drinks are sealed with mouth iron seal. Then, whether the combination of metal cover with glass container, if the sealing performance is qualified, or how to detect the overall sealing of glass container... Those are very much concerned by manufacturers and consumers. Hereinafter, Labthink will give a brief introduction to C660B Leak and Seal Strength Tester for glass container sealing tests. 1. Put an appropriate amount of distilled water in the vacuum chamber, fix the sample on the sample fixture, and then immerse it in the distilled water. At this time, the distance between the tip of the sample and the water surface shall not be less than 25mm. Two or more specimens can be tested at a time, as long as the leakage at any part of the specimens are observed during the test. 2. Cover the sealing cover of the vacuum chamber, turn off the exhaust tube valve, and then open the vacuum tube valve to vacuum the vacuum chamber. Adjust the vacuum degree at 30 ~ 60 kPa to one of the following values: 20, 30, 60, 90kPa, etc. Stop the vacuum at a certain vacuum degree and keep the vacuum for 30S. The adjusted vacuum value is determined according to the characteristics of the specimens (such as the packaging materials used, sealing conditions, etc.) or the provisions of the relevant product standards. However, the specimen should not burst or crack at the seal due to the internal and external pressure difference of the ambassador sample. 3. Observe the escape of the sample gas by visual inspection to determine the overall sealing performance of the glass container(s). Observe the leakage of the specimen(s) during vacuum retention, depending on five successive bubbles. A single isolated bubble is not considered as specimen leakage. 4. Open the inlet tube valve, make the vacuum chamber connected with the atmosphere, open the seal cover, remove the specimen(s), wipe the water on specimen surface, and open to check
