The integrity of the sealing of the products is of concern to all food manufacturers, especially in the case of products packaged in a protective atmosphere where this integrity is a key factor in not endangering the expiration of the product.
In most food production facilities packages leakage occurs mainly due to contamination of the seal by food or due to mechanical problems related to pressure, heat and duration of the sealing process. Both problems can be easily solved with a Flexpak Inc leak detector.
The oxygen and carbon dioxide indicators can be used to monitor the quality of the food. They can be used as leakage indicators or to verify the efficiency of, for example, an oxygen scavenger. Many of these indicators acquire a color change as a result of a chemical or enzymatic reaction (the most used dye for leakage indicators is methylene blue, whose color change is based on an oxidation-reduction reaction). In Japan, oxygen indicators are widely used with many fresh or prepared foods packed with an oxygen absorber in a transparent plastic or glass container. Carbon dioxide indicators are now starting to be commercial.
An ideal indicator to control the quality of packaged foods would be one that indicated the deterioration or lack of freshness of the product, in addition to excessive temperatures or container leakage. Numerous patents exist in which mechanisms of indication of freshness are described based on the detection of volatile metabolites produced by the aging of foods such as carbon dioxide, diacetates, amines (of fish), ammonia and hydrogen sulfide.
Flexpack Leak Detector Machine:
Leak Detector / Device to test the integrity of waterproofing for the packaging industry Flexpack leak detector is a tester control quality of the integrity of the waterproofing, ideal for testing the integrity of the seal detection leaks for many types of packaging including: three-sided bags, self-supporting / rigid / standing bags, side gusseted bags, bottom sealing bags, rigid trays with lid material, packing filled with modified atmosphere (MAP ) / protective atmosphere (EAP) and many other applications for food packaging or medical packaging.
The flex-pack leak detector offers manufacturers of food packaging machines, and the food industry in general, a unique solution to detect leaks in protective atmosphere food packages. Whether it is a large leak or a small one, undetectable to the naked eye or by the water bath method, the unique flex-pack technology can detect any leakage without tracer gas and without damaging the container.
Consistent quality control and Process Monitoring:
Flexpack leak detector is simple, reliable, repeatable, and provide consistent quality control and process monitoring…
- Test the minimum point of success
- Test the point of failure
- Perform an altitude simulation
With this tester, you can adjust the settings of the machine to test the integrity of the impermeabilization, such as the rest interval, the temperature and the pressure to correct possible problems of the integrity of the seal that are found during the test.
The flex-pack leak detector is a sealing quality control device consisting of a transparent vacuum reservoir, a vacuum system, a control valve and the gauge that indicates the level of vacuum. The vacuum tank is mounted on a stainless steel support. During the test the package is submerged in the tank, the lid is closed, and the vacuum valve is activated. At that time if there is a leak, the quality control inspector can easily see the air in the form of bubbles escaping from the package. By increasing the vacuum level, the breaking point can be tested until a seal failure occurs. A complete test can be done quickly and easily!
