Why Packaging Leak Testing Is Critical for Your Business

Leaks in packaging are considered one of the most frequent causes of failure, customer complaints, and even recalls. The smallest flaw in the seal of a bag will cause air or other contaminants to pass through, which will cause the product to deteriorate faster and may even lead to food poisoning.

Leak testing of packaging goes beyond mere quality control and becomes a legal requirement imposed by regulatory authorities and retailers. Therefore, having an effective vacuum leak tester for packaging should be considered more than just an investment in quality, but also in business security.

Consequences of Skipping Vacuum Leak Testing:

• Early spoilage of products and shortened shelf life, resulting in stock disposal
• Complaints from customers and poor reviews are hurting the brand image
• Breaches of regulations and possible product recalls for all manufacturing lots
• Danger of contamination in the packaging of drugs and medical devices – a safety risk to patients
• Waste of raw material, returned shipments, and additional costs associated with manufacturing work
• Loss of access to retail and international markets following third-party audit failure

Vacuum Leak Tester for Packaging: Product Overview

The Effective Lab India vacuum leak detector is a small, benchtop machine that checks the tightness of different types of packaging quickly and effectively.

The test sample, which could be a flexible pouch, hard bottle, blister pack, or thermoform tray, is dipped into water in a clear vacuum chamber. The chamber is subsequently subjected to vacuum to a pre-determined level.

If there is any leakage in the test sample, it will become obvious through the appearance of an air stream that emerges from the packaging.

This bubble emission technique is commonly referred to as the immersion vacuum leak test. It is the most frequently used leak detection technique employed in the testing of flexible packaging.

This technique is not only quick (tests are normally completed within 30 seconds) but also easy, because all you need is water.

The HMI touchscreen offers a user-friendly interface wherein users can input the target vacuum level, the test duration that ranges up to 999 seconds, and the acceptance criteria.

This instrument shows the results in real-time, and such can be digitally recorded for documentation purposes. With its digital pressure sensor, the unit measures vacuum with a least count of 1.0 mm Hg and 0.5% accuracy of measurement.

How Does the Vacuum Leak Tester Work? Step-by-Step

In the Effective Lab India vacuum leak detector, the immersion bubble emission technique is employed, which is considered one of the easiest and quickest ways to identify leaks in flexible and rigid packages. The entire testing procedure is as follows:

• Stage One - Specimen Conditioning: Place the specimen under test, a pouch, a bottle, a blister pack, or a tray, in the chamber filled with water. Make sure that the specimen is completely immersed in the chamber and closed with its cover.
• Stage Two - Parameter Input: Input the vacuum level (mm Hg) you wish to reach as well as the required testing time (in seconds). You can store the entered parameters as a profile.
• Stage Three – Draw Down of Vacuum: The vacuum pump starts to evacuate the chamber to the required pressure level. Pressure changes are monitored by the digital vacuum gauge.
• Step 4 – Leak Detection Observation: With an increase in vacuum within the chamber, there will be high internal pressure inside the faulty pack that causes the flow of air via the fault site. This process results in a constant flow of air bubbles, which can easily be seen with the naked eye on the clear acrylic lid. The position of these bubbles clearly shows the exact area where there is leakage.
• Step 5 – Pressure Hold Test Analysis: Another way to conduct this test is to check the pressure hold analysis for rigid packs, as it involves assessing the stability of the vacuum during the hold period.
• Step 6 – Test Data Logging: All the data related to the test, i.e., the outcome and its parameters, will be recorded digitally in the computerized data log.
• Step 7 – Vacuum Discharge and Specimen Withdrawal: At the end of the test, the vacuum will be discharged, and the specimen will be withdrawn from the chamber.

Frequently Asked Questions (FAQs)

Q: What is the difference between a vacuum leak tester and a vacuum decay leak tester?

A: The traditional vacuum leak detector device, like Effective Lab India, operates using the bubble generation technique (immersion). In this procedure, the packaging material is dipped in water, and a vacuum is applied in the test chamber. Leaks are determined through the release of bubbles emerging from the leakage point.

This technique is well-suited for flexible materials such as pouches, sachets, and blisters, which provide not only an outcome whether the test item passed or failed but also the exact location of the leakages. The vacuum decaying method for detecting leaks is another form of vacuum testing that does not need water submersion.

It works on determining the pressure decay rate in a closed test fixture and is suitable for destructive testing of rigid packages and some semi-rigid packages. Both methods are based on ASTM standards.

Q: How do I choose the right vacuum level and test duration for my packaging?

Answer: The right vacuum level and holding time will depend on the material used for packaging and the item contained in the pack, along with the specific test standard used.

ASTM D3078 is one of the most widely used test standards for assessing the emissions of bubbles from flexible packaging. As a thumb rule, flexible pouches with food items require a vacuum level of 10 to 27 inches of mercury (254 to 686 mm Hg), with a holding period ranging from 30 seconds to 3 minutes.

Different parameters apply to pharmaceutical blister packs and rigid containers. Technical experts at Effective Lab India advise the appropriate parameters for each packaging type purchased from us, and we have the provision of saving test profiles through our HMI panel.

Q: How often should the vacuum leak tester be calibrated, and does Effective Lab India provide calibration services?

A: For quality control laboratories in food and pharmaceutical industries, calibration of the equipment is advised to be done at least once per year or more often if the equipment is under constant use or if any deviation from the normal performance of the instrument is noted.

The Effective Lab India vacuum leak tester features an integrated calibration option that enables easy calibration to be performed by the lab technician without the need for special devices. In case of third-party or NABL traceable calibration services needed for compliance with quality assurance protocols like ISO 9001, FSSC 22000, or GMP, you can book calibration services provided by us, which will be fully documented.
