Packaging Leak Test in the Food and Pharma Industry
The importance of packaging integrity and how advanced non-destructive packaging leak detectors improve package quality
Packaging plays a crucial role in the preservation and safety of products within the food and pharma industries. Maintaining seal integrity throughout the supply chain not only ensures product quality and safety but also upholds consumer trust. However, despite advancements in packaging technologies, certain persistent issues continue to challenge industry professionals.
Package Leaks Despite Integrity Testing
A significant issue for the industry is when food like coffee spoils even after passing leak tests. This can lead to significant losses and decreased consumer confidence in vacuum packing. Investigating the root causes—be it microscopic punctures or seal imperfections—is essential for developing more reliable testing protocols.
Another critical aspect to consider is the impact of environmental factors on packaging performance. Temperature fluctuations, humidity, and exposure to light can all compromise the integrity of packaging materials, leading to spoilage or contamination.
While packaging is a vital component in safeguarding food and pharmaceutical products, ongoing challenges require an advanced approach. The industry can improve process quality by solving problems like leaking packages for better and more reliable solutions. This not only protects the products but also fosters trust and customer satisfaction.

The following list highlights common packaging testing topics, the types of packaging affected, and the methods used to address these challenges
Burst Packaging in Water Bath
Testing snack foods in capsules in water baths to mimic the stress of transportation and handling is a well-known method, also called bubble test or bubble leak test. Such traditional methods sometimes fail to predict failure points accurately. The "DIY Test" method has emerged as a practical way to gauge packaging resilience under real conditions.
Non-destructive Testing of Food Packaging
For sensitive products like nuts and dried fruits, the Modified Atmosphere Packaging (MAP) technique is common. Employing non-destructive testing, specifically dye penetration test can detect vulnerabilities without damaging the product. This method ensures the longevity and freshness of packaged goods without the need for invasive procedures.
Claims of Faulty Packaging
Faulty packaging claims, particularly for powdered products in protective gas packaging, can be challenging. Rhodamin dye test finds small leaks and ensures protective atmospheres prevent spoilage.
Paper in Water Bath Testing
Cheese products, often packaged in metal cans, undergo rigorous testing including the water bath test to ensure no water ingress that could lead to spoilage. This method helps manufacturers guarantee the hermetic sealing of cans against liquid penetration.
New Packaging Trials in Water Bath
Innovative packaging solutions like coffee in pouches often require thorough testing to ensure their efficacy with a CO2 tester in water bath trials to check gas levels in pouches. This helps prevent germs and maintain product freshness. The tester ensures that the gas levels are correct for preserving the product. It also helps in extending the shelf life of the product.
Container Closure Integrity Testing (CCIT)
Container Closure Integrity Testing (CCIT) is essential for ensuring pharmaceutical packaging, like vials and syringes, is sealed properly. It uses various methods, including vacuum decay technology, which creates a vacuum in a chamber around the container and detects leaks by measuring the rate of vacuum decay. While CCIT is crucial for maintaining product quality, challenges include accurately detecting tiny defects and limitations like the potential for some methods to miss extremely small leaks or be destructive.
Pressure Decay Leak Test
The Pressure Decay Leak Test is effective for detecting packaging leaks in rigid containers but has limitations. It is less sensitive to very small leaks, especially in flexible packaging, and can sometimes be partially destructive. Environmental factors like temperature and humidity can also affect accuracy, and proper setup is crucial to avoid false results. Despite its usefulness, these challenges make it less suitable for certain types of packaging and applications.
Further Innovations and Testing
The food and pharmaceutical packaging industry continually seek advancements to enhance product safety. For instance, the testing of chip bags and medical thermoform packaging ensures durability and integrity. The MAP testing for these applications is crucial for validating the effectiveness of new packaging designs and materials.
Emerging Solutions
Emerging solutions like aroma vent sachets for minced meat represent the innovative spirit of the packaging industry. These sachets not only help maintain product integrity but also enhance consumer appeal by improving product freshness and aroma.
Innovative package leak detection
As the food and pharmaceutical industries evolve, so need the methods and technologies for packaging and testing be up to date. These innovations are vital for addressing the ongoing challenges of packaging integrity and safety.
The Contura S-Series from INFICON represents a significant advancement in packaging testing technology, overcoming the limitations of conventional methods like visual inspection and water baths. Traditional methods often fall short in detecting minor leaks, which can compromise product quality and safety. The package leak detector from INFICON addresses these issues by using a non-destructive and highly sensitive pressure rise method to detect leaks with precision and reliability.
This innovative approach allows for rapid testing of various packaging types, including flexible and rigid containers, without damaging them. The system identifies even the smallest leaks, which ensures that packaging integrity remains intact, enhances product safety, extends shelf life, and increases efficiency in the quality control process.
