We all agree that leakages in food packages can be a great turn off. Leakages more often lead to hastened food spoilage and contamination. It is, therefore, important for food processing and packaging companies to invest in leak detection equipment to ensure their food packages are tight and devoid of any chances of leaking before the end consumers utilize them. Due to technological advances, there are now a number of leak detection equipment at their disposal.
This equipment operates on the principle of measuring the reactive force generated by a food pack when it’s subjected to vacuum. The change in this force is an illustration of packaging integrity. Package leak testing identifies any weak seals thus highlighting quality assurance issues. With MediTEST MO12C, only a few seconds are needed to detect holes up to 10 microns whereas its non-destructive nature allows for waste reduction.A computer based virtual instrument control system, which features a touchscreen HMI, guarantees easy to read results, indications, and graphical test data to assist in analysis. MediTEST MO12C-4 is capable of inspecting up to four food packs at ago.
Pack-Vac Leak Detectors
This leak detector equipment is trusted by many food manufacturers because it has continued to guarantee customers safety of the food in the package. A systematic food package testing system that involves Pack-Vac Detectors allow manufacturers to set-up packaging lines quickly and reliably.
Continual process monitoring using Pack-Vac Leak Detectors will detect sealing anomalies on time, thus leading to improved production yield. To ensure the best standards, manufacturers are encouraged to add an Electronic Controller for altitude simulation to ensure the food packages are tested to the ideal conditions.
This detector allows users to perform vacuum tests in less than a minute. For a good number of packages, the unit is partially filled with water for the test. You just drop your sealed package, close the lid and then you engage the vacuum device as you watch for bubbles.
FLEXPAK Leak Detector
Flexpak leak detector is a high-quality packaging seal integrity detector that adds quality packaging applications.
This detector can be used for a range of package types starting from stand-up pouches, rigid trays, sachets, form fill seal, flow wraps, and thermoform packages. The detector uses solid stainless steel working parts to avoid breakages and ensuring highest quality standards. Food packages that require testing are first placed in a clear acrylic vacuum water tank, then the lid is closed before finally engaging the vacuum. Thereafter, one can choose a testing method based on his/her company’s requirements and standards. Flexpak guarantees a complete leak test results within few second.
Because quality engineers seek perfection while product managers push for greater output, they have always been at odds. However, serving both agendas is now possible thanks to advances in leak detection devices. Modern leak detection equipment helps to speed up the process of quality control without sacrificing accuracy.
Testing every product is a must since the consequences of component failures often come back to haunt manufacturers in the form of high liability claims, particularly when manufacturing for critical applications. With advanced knowledge about what to look for when it comes to Leak Detection Equipment, test engineers can increase the chances of rolling off quality assured products without acting as a hindrance to production schedules. The following tips can be helpful when it comes to picking the most suitable equipment for your application.
1. Insist on application specificity
Because even minimal leaks can mean the difference between success and failure of a product, leak testing equipment demands attention to detail. As such, you cannot take a one-size-fits-all approach.
2. Always opt for automated testing equipment
Test equipment should always feature fully automated or semiautomatic leak detection systems to streamline the delivery, clamping, sealing, marking, and testing of products. Opting for fully automated systems allows you to minimize changeover costs and time, remote-start input, and PLC connectivity, speeding up the process of testing.
3. Examine the ease of operation
Regardless of a leak tester’s capability, the equipment is nothing if it is not easy to use. Programming should be simple and straightforward. Most current leak testers offer a relatively simple programming process featuring a high-resolution graphic interface. The programming software also includes preformatted test configurations that you can easily modify to each application.
4. Seek system flexibility
Since the introduction of new components, specification changes, and product variations all mandate alterations when it comes to testing parameters, flexibility is a necessity for future upgrades. High-quality leak testers accommodate such options, saving the expense of acquiring a new piece of equipment.
5. Hold out for output options
A good paper trail is quite important when it comes to certifying the manufacturing process. As such, complete leak detection equipment should include options for documenting the process of testing. For archival purposes, a tester should be at least capable of inputting leak rates and other results into a database or spreadsheet.
6. Demand an outstanding support from your supplier
Like most sophisticated devices, leak detection systems are only as good as the support offered by the manufacturer. It is notable that the number of years any supplier has been in this particular business counts seeing as experience adds to their knowledge when it comes to following up on applications. Always use reputable suppliers like Flex Pak Inc.
7. Consider repeatability
Unless you can repeat a test and come up with the same results, it has no meaning. The automation of leak detection systems improves reproducibility since the testing process is not subjective, unlike relying on an operator’s memory to initiate a sequence of tests. As incorporated into some leak detection systems, the ability to automatically compensate for alterations in temperature and humidity also helps to ensure the consistency of product quality.
Leak detection is always a priority when storing, handling or transporting packages containing gas or liquid substances. Even compounds that are not hazardous through direct exposure can create environmental and contamination concerns if they get out. Fortunately, the bubble emission test is a simple and relatively reliable technique to determine if a container is in good condition. The test does require some specialized leak detection equipment, but it is often a wise investment for preventing financial loss due to leaks.
How The Test Works
The concept of the bubble emission test is actually quite simple. Containers are submerged in a container filled with water, then all of the air is sucked out through a vacuum. This puts pressure on the air inside the package, causing it to inflate slightly. Existing packaging faults or breaks in the lining will cause visible air bubbles to escape from the container and rise to the surface of the water.
Workers conducting bubble emission tests must follow operational procedure carefully as they establish an environment to test product packaging. If the pressure exerted on the container grows too high, it can cause air to leach out of porous material to the outside of the container. This may appear like a positive leak detection result, which harms the integrity of the testing process overall. The appropriate settings for the test depends on the nature of the specific container and contents.
When to Select the Bubble Emission Test
The bubble emission test is designed for packages that have some open space inside, so there is enough air to exert a meaningful amount of pressure on the inside of the container. Liquid and gas compounds stored inside of smaller or compact packages should be subjected to the dry chamber test instead for better results. Bubble tests can take 30 seconds or more to thoroughly analyze a single container, so additional Leak Detection Equipment may be needed to examine them in a timely manner.
Reliable and Simple Leak Detection
The bubble emission test is not 100 percent accurate, but it is relatively easy to set up and does not require significant financial investment. Specialized supplies, like sterile medical material and volatile chemicals, may also be subject to specific standards that define the scope of testing procedures. Businesses should research the requirements enforced by the appropriate agencies in their industry to ensure their testing process meets essential requirements.
