Many people are always reluctant about changing or inspecting the food packaging material they use when they are off to the grocery. While this is true, food packaging materials should be checked for leaks to ensure you don’t run into havoc. However, consumers must rely on the lead detection equipment to detect any form of leaks in their food packaging equipment. You should also know that the leak detection method used by the manufacturers is not always 100 percent correct. Food poisoning, in some cases, emanates from leaks in the food packages because it can come into microorganisms that contaminate the food. The consumer must always be aware of the equipment and method that can be used to detect leaks in food packaging material to solve this problem.
Let us look at the following methods used to test leaks.
1. Ultrasonic Measurement
As a consumer, you should know that all leaks produce sounds related to their size. The sound’s frequency can be low or high depending on the leaks. Small leaks always produce a higher frequency. Therefore, you can make use of the ultrasonic leak detector to detect the high-frequency sounds from the food product packages. The ultrasonic leak detectors are small, hand-held gadgets that that are accompanied by a meter, a pair of headphones, and a sensitive adjustment nozzle. You can easily measure for leaks in the food packaging material for any leaks found. Also, the leaking rate of the material can be identified by the leak packaging material.
2. Bubble Test
Unlike the previous method that makes use of the ultrasonic measurement, this method uses a simple application. If you suspect any leakage of the food product package material, the package will be pressured by the customer. In the end, you will also submerge it in the water. If you see any form of bubbles from the water, it is clear that there are leaks. The rate of bubble development denotes the leak extent.
3. Pressure Decay
According to some laws in the scientific world, the leak packaging material pressure reduces the internal object pressure. Before you test for any leak in the package, therefore, the material must be changed using some amount of dry air such as nitrogen at that dry level. You will monitor the temperature for some time. When the material pressure comes down, it confirms that the food packaging material shows some leakages. Because it is simple, reliable, and compact, many people prefer using this method. Also, the method is relatively free from bias and cheap.
4. Vacuum Decay
When you talk about the vacuum test, you are talking about the opposite of the pressure decay method. It also involves the evacuation of the package material parts. This means you stabilize its pressure. You measure any form of pressure building up in the packaging material. However, not any packaging material can be subjected to this measurement. Therefore, you must work to develop certain conditions for certain types of material. Because you can’t affect it by any form of temperature fluctuations, the food packages can survive in a vacuum. This is one of the best methods used in identifying sensitive leaks as the best leak detection equipment.
5. Helium Sniff
For this procedure to amount to effectiveness, a helium sniffer can be used as a leak detection equipment to determine the occurrence of leaks in the food package material. The pressure of helium is directed to the food packaging material with enough force. You scan the surface for any helium leaks using the helium sniffer. The concentration of helium in the area will increase if the surface leaks. This is an efficient method as it identifies the leak location.
Food companies can suffer massive losses when their products are rejected because they are not sealed correctly. Leaks in the packaging expose food to air, which can compromise its quality or shorten the period to expiry. It is essential for companies to invest in leak detection equipment that will help identify these leaks and prevent rejection of products in supermarkets and grocery stores.
Technological advancements in the food production industry have improved and simplified the processes of leak detection in packaging. This has, in turn, reduced the losses incurred by firms as a result of rejected products. Here are some of the improvements that have resulted from the adoption of technology in leak detection.
1. Miniaturization and Network Integration
Gone are the days when leak detection equipment and sensors were big and bulky. Technology has led to the introduction of small automated leak detectors and sensors that can be integrated into packaging and plumbing systems. Additionally, detectors are now wireless. This means that you can incorporate them into both the packaging system and a network and have great results. Automation has made it easy for companies to monitor the functioning of leak detectors through computer devices, and this has led to a significant increase inefficiency and accuracy in leak detection.
2. Process Automation
Before the introduction of technology in leak detection, the process used to be extremely labor intensive, and companies required a lot of resources in order to detect and prevent leakages. Workers had to inspect all the packages by hand before preparing them for shipping. Not only was this time-consuming, but it was also inaccurate and inefficient. Leak detection equipment has automated the processes, which has eliminated the need for extensive labor involvement. The use of automated sensors increases speed and accuracy in the process. Besides reducing losses, these improvements have also cut down costs for packaging companies and led to improved efficiency in their operations.
3. Timeliness in Leak Detection
Traditional leak detection equipment could only detect gross leaks in packaging after containers had already been packaged, warehoused, and shipped to the retail stores. Such mishaps often led to substantial losses for food companies. However, today’s systems can provide early warning signs before the products get to the consumer. Processes such as online leak testing for bottles and containers protect the process from random issues that cannot be identified through sampling. Also, the equipment not only detects leaks, but they can also isolate the likely points of origin-whether it’s due to malfunctions in certain stages of the process or the quality of the packaging. This way, it is possible to prevent any amounts of leaks at the right time.
4. Instant Notifications Help Protect Business Reputation
Obtaining real-time results in leak detection is essential in promoting efficiency and reducing losses in the food packaging industry. If the company doesn’t instantly identify the leaks as they occur, then it may have to recall the products once they have been shipped to the consumer. This can hurt the company’s reputation, lead to losses due to rejection, and increase the chances of facing liability lawsuits. Since today’s leak detection equipment allows real-time detection of leaks, they ensure that these issues are handled within the warehouse before the products are dispatched into the market.
Technology has streamlined the process of leak detection by introducing advanced equipment and automated processes. Further innovations in the industry are bound to bring about more sophisticated systems that will improve the detection of leaks in food packaging. These will save companies a significant amount of money that is always lost directly or indirectly due to the way in which the products are received in the market.
During the production of food products, manufacturers go through meticulous processes of ensuring that their products are perfect at the packaging stage. They are required to abide by the set standards regarding the integrity of food packaging. However, during the manufacturing process, small leaks can occur on the packaging, and these affect the general quality of the product. Leak detection equipment identifies these leaks, increase the shelf life of foodstuffs, and minimize the chances of loss due to product rejection.
The equipment used in leak detection comes in various types and utilize different technologies; usually depending on the food commodities being packaged. There’s a need to consider the following factors before choosing the appropriate equipment for the warehouse.
Reliability of Equipment
Manufacturing plants and packaging warehouses are usually fast-paced with time restraints and packaging requirements. Speed and efficiency describe these environments as workers have to keep up with the continuously running conveyor belts and other equipment. It is important to invest in reliable leak detection equipment that can deliver accurate results without making mistakes. Supervisors don’t have the time to run multiple tests due to the inefficiency of equipment. If the initial results are inaccurate, one can end up presenting flawed food products in the market.
Leak detection systems in warehouses comprise of large mechanisms with detection monitors. The best ones can perform tests on various types of packaging in less than a minute. Invest in such equipment that can handle the pressures and time constraints without compromising on accuracy.
Ability to Detect Leak Source
Food products go through various manufacturing stages. As they go through the different processes, they can be compromised due to the quality of the material used for the packaging, cap, or seal. Sometimes, even the strongest materials can tear and open or develop micro leaks as they go through the processing and production stages. You need leak detection equipment that not only identifies the leak, but it can pinpoint where the source of the leaks.
After testing, the manufacturer should be able to know if the leak is as a result of flaws in the turnout process or the quality of the product packaging. With this knowledge, one can quickly fix the problem and prevent future incidences of leaks. However, if the equipment cannot identify where the leak is resulting from, one may end up fixing the wrong problem and handling many similar leaks in the future.
If leaks aren’t detected in real time during processing, the manufacturer may be forced to recall the product after it has already hit the shelves in grocery stores and supermarkets. This can damage the reputation of a brand and cause millions of losses to the company. Utilizing quality leak detection equipment is the best way to test the quality of foodstuff and strength and integrity of its packaging.
Food packaging is not something we often think about while out shopping. Instead, we usually grab and pay for items packaged in tightly sealed bags. While most of us can easily recognize the smell and appearance of spoiled food, it is not a common occurrence in large supermarkets and grocery stores. As a result, the thought that we might ingest contaminants, impurities, or become ill from the food in these outlets will rarely cross our minds. Even though we probably do not understand the entire process of food packaging and how it works, our trust results from the fact that the leak detection equipment and technology used rarely fail.
Until it goes through a process of inspection, regulators keep food from reaching the shelves of large supermarkets and grocery stores. Leak detection, usually performed during the packaging process, is part of this operation. You need to use high-quality leak detection equipment to perform effective inspections. The apparatus used needs to be reliable and accurate, enough to discover the leaks in a multitude of bags repeatedly.
Most of the packaged foods displayed on supermarkets come from large warehouses. Thanks to time restraints and packing requirements, the environment in large warehouses is usually fast-paced. Workers are expected to move fast and keep up with the huge conveyor belts that run continuously. In such a setting, you need reliable leak detection equipment that can handle this level of stress. The leak testers used in warehouses are usually large industrial mechanisms that have detection monitors. Such units have the ability to perform full tests on various types of packages in as little as half a minute.
Pinpointing potential issues
In addition to identifying the location of a leak, leak detection systems are meant to determine the cause of that leak. Industrialists need to know whether the leaks are a result of processing or production tasks. Although food packaging manufacturers usually choose the strongest materials for their products, sealing issues can still arise. Regardless of the strength of a package, it can still tear and open in the process of moving it from one place to another. Leak detection equipment lets manufacturers know whether it is their product packaging or turn-out process that is flawed.
The importance of testing
Packages usually go through numerous tests before reaching the supermarket. Pressure checks and bubble testing are some of the most effective tests. While pressure checks test the integrity and strength of packages, bubble testing identifies the small holes that are excellent entranceways for bacteria. Processing will cease without such tests, as a result of which products won’t make it to the market.
You can recognize a fresh product by looking at its packaging and seal. Air-filled packages will deflate slightly if they have been on display for some time while vacuum-sealed consumables will look unpleasant when rotting.
The most ideal way to decide whether you have a leak in your pipes framework, is by first checking your water meter. You can do so manually or by using Leak Equipment.
1. Ensure no water is being leaked inside or outside of your home.
2. Find your water meter and check the break marker to check whether it is moving. Contingent upon the brand of your meter, the hole marker could be a little triangular molded dial or a little silver wheel that turns when water is moving through the meter.
3. On the off chance that the dial is moving, odds are, you have a leak.
Or, then again, you can likewise take a meter notation and hold up 1 or 2 hours and take another meter reading(ensure no water is utilized amid this time). In the event that the perusing has transformed, you have a break. And it is time to use Leak Equipment.
After you have verified that you have a release, the following stride is to decide whether the break is inside or outside of your home.
1. Find your home’s basic stopper valve and stop the water at the valve. Ordinarily, you will locate the stop valve in the storm cellar or carport straightforwardly behind an open air spigot, or outside beneath an open air fixture.
2. Once more, check the hole marker for development or utilize the meter perusing technique, making a point not to utilize any water amid this period.
On the off chance that you can’t find the hole, you may need to call a handyman. Some other cases that may be encountered are:
Spilling spigots are for the most part a consequence of a ragged elastic washer. The washer on a sink is typically situated under the handle. These are moderately simple to supplant, on the off chance that you have the correct apparatuses. It requires stopping the water under the sink or at the fundamental shutoff valve and evacuating the handle.
Latrine breaks can squander several gallons and generally are noiseless. Indeed, even a little break can indicate a considerable measure of squandered water and cash after some time. Luckily, most can holes are simple and cheap to repair.
Flapper Valve Leaks
The most well-known explanation behind a spilling can is one that has a shamefully working or fixing flapper. The flapper is the elastic valve in the base of the tank that lifts up when the can is flushed.
Customers purchasing packaged food items might take the time to look at expiration dates, but it is rare that the package integrity crosses their minds. There are times it is obvious that a package is open and not safe to buy, but a small pinhole or tear in the packaging material might not be so easy to detect. Avoiding this problem can be as easy as using leak equipment that tests the integrity of the packaging right off the line.
Integrity of Food Packaging
Food items can make it all the way from raw material and processing with top quality, but fail in the end through packaging problems. Leak detection equipment is important in the food manufacturing industry to guarantee customers the product is both safe and of the best quality. The intense over-sight given to the food industry demands rigid controls of every phase in the creation of products that are sold on the market for public consumption.
Testing for Packaging Consistency
There will always be the occasion that a package does not get properly sealed. Limiting these instances are the goal of using leak detection equipment devices. Every food manufacturer strives to have all packaging equipment operating in a consistent manner. Monitoring is the only way to guarantee this is happening.
Discovering Packaging Equipment Problems Early
Foods can be prepared as an end-product in many forms. There are powdered, baked, fresh, frozen, flexible sealed, rigid sealed and even resealable products. The product will only be as good as the package integrity. Package failure can make products dangerous to eat. This can set the manufacturer up for expensive recalls or lawsuits. Discovering a packaging equipment problem right away is the best solution. Fixes can be made to ensure all products are getting packaged the right way the first time.
Leak Detection Equipment That Is Easy to Use
Leak equipment is not that difficult to operate. It can be used as a consistent quality management tool. A specified number of samples can be pulled and tested from each packaged batch of food items. The equipment will detect problems, if any exist. The equipment is normally flexible enough to handle all types of food packaging materials and test for needed specifications.
Non-Destructive Testing Methods
Methods of testing can be employed that allow for faulty packaged foods to be tested in such a way that it is non-destructive. The food items can be sent back down the line to be re-packaged in the correct manner. This saves the manufacturer money and product. This brings ultimate food safety measures without a lot of hassle and food waste.

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.

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.
