Seal Integrity Testing for Food Packaging

Maintaining the reliability of food packaging seals is a vital part of product safety and quality. The failure of a package’s seal could lead to spoilage, product recalls and reduced brand image.

Food packaging leak testing methods are often non-destructive, and can be conducted on production lines to ensure 100% seal integrity. Dye penetration tests are an example of this type of test.

Burst Leak Test

A food package should protect its contents throughout distribution and storage. This is why manufacturers regularly test seal integrity and use a range of methods to do so. A minor defect like a bubble leak in the packaging can significantly compromise the food product’s quality and safety.

Among the most popular seal integrity testing techniques is the burst leak test. It involves pressurizing a sample of the sealed package and submerging it in water to see if any air bubbles appear around the seal area. This type of test is usually performed in an acrylic vacuum chamber and complies with ASTM standard F1140.

Another common method is the creep test, which consists of inflating a package to a predetermined pressure and maintaining it for a specified period of time. The pressure on the package is usually measured and a pass/fail result is declared when the package is inspected after the testing period. This test can be either restrained or unrestrained, which influences the results since a restraining device limits the expansion angle and allows for a differentiation between packages with strong or weak seals.

Lastly, the peelability test is used to measure the force required to open a peeled package. It is usually conducted on a peelable medical package and provides force data that can be interpreted to help with validation and process control.

Leakage Test

Seal integrity testing is a necessary step for any manufacturer producing packaged products. The integrity of the packaging helps maintain product quality, protects the products from environmental impacts and extends the shelf life of the food. As such, maintaining the reliability of the seals is critical for food and pharmaceutical manufacturers.

One of the most common techniques for testing package integrity is using a leakage test to measure the strength of a seal. This type of test is nondestructive and works by subjecting the package to a certain amount of pressure or vacuum. The machine will then detect any changes in pressure that indicate a leak in the seal.

A food packaging leak detector is a tool that can be used to determine the quality of a seal on a variety of different types of food packages. The device uses a computer to monitor the pressure inside of the package, and it will notify the operator when there is a problem. This will allow the operator to take corrective action before the food goes bad or the packaging is compromised.

Another popular method of detecting leaks in flexible or semi-rigid foods is to use the dye penetration test, also known as the standard test method for detection of leaks in nonporous, flexible barrier materials by dye penetration (ASTM F3039 – 15). This technique involves immersing the package into a solution of water and a specified indicating dye. The package is then inspected after a period of time to see if the dye has penetrated the package seal area.

Moisture Test

A moisture test measures the ability of a package to resist water and air ingress. The test is done by placing the sealed food product in a container under controlled laboratory conditions. The test is performed on a pass or fail basis.

If your food packaging does not contain a good barrier to the ingress of moisture, it can lose its shelf life and quality. This can lead to a loss of revenue for your company due to product recalls, as well as tarnished brand image. Moisture test results help you select the right materials for your packaging. This ensures your product stays fresh during production and distribution, and saves you costs on food waste.

The Moisture Leak Test is one of the most common tests for evaluating the integrity of a heat-sealed package. The test uses a dye penetrant to locate leak channels within the seal area of a package. The test can be conducted with either the injection method or the edge drip method. The injection method involves injecting a dye penetrant into the package along its longest edge. The edge drip method involves using a container with a length that accommodates the longest edge of the packaged product.

The physical test methods used to determine a package’s integrity are more reliable than biological challenge tests, which may be prone to errors. However, physical testing can be expensive and time-consuming. New nondestructive sensing technologies are advancing as an alternative to traditional testing methods.

Environmental Test

The gas bubble leak detectory of food packaging is crucial to prevent the deterioration of packaged products. This ensures the product stays fresh and sanitary, which is especially important for delicate foods that are prone to contamination from outside factors like air or moisture. This can impact both the consumer’s health and the brand reputation of a company. Even a minor leak in the packaging can cause this to happen, and companies that rely on these types of products must have a robust package testing machine to detect any problems with their packaging immediately.

Traditionally, visual inspection was the main method used to determine the integrity of packaging. However, micro-leaks and discontinuities in the seal area made it difficult to catch these issues with this method. New test methods have been developed to assess the quality of packaging without requiring the physical manipulation of the package. For example, the patented nondestructive airborne ultrasound technology of PTI’s Seal-Scan system can quickly and accurately scan seal areas to identify defects including micro-leaks, discontinuities, misaligned seals and incomplete seals.

Other test methods include the dye penetration test (ASTM F3039 - 15), where an operator applies a dye to the sealed area and then examines the other side of the seal after a specified period of time to see if the dye has transferred through the seal. The tensile strength test is another mechanical test that measures the force required to pull apart a 1-inch section of the package seal. Creep tests and drop testing can also be conducted to measure seal strength, in which the pack is inflated to a percentage of its burst pressure and then held for a period of time to see how the package responds to stress.
