How vacuum leak tester is beneficial for testing vacuum leaks in food pouches?

One of the most important aspects of packaging is ensuring that products are sealed tightly and securely. This is especially important for products that are sensitive to air or moisture, as even small leaks can cause problems. Thus, testing your products against vacuum leaks is important to assure about the leak integrity of products, especially food packaging products. We at Presto have come up with one of the effective lab testing instruments known as a vacuum leak tester that is highly useful in testing the integrity of foiled cups and other packaging products to the effect of vacuum.

This testing equipment will help to assure that the seal should be unbroken and should be perfectly fine by ensuring its leak proofness. Here in this blog, we are going to discuss brief information about how Presto vacuum leak testing equipment is helpful in testing the vacuum leaks of food products. But first, we will discuss how a vacuum leak tester is helpful in ascertaining the seal integrity of packages with ease. So, let us get started!

What is a vacuum leak tester and for what purpose it will be used?

The vacuum leak tester is a precise testing instrument offered by Presto that is used by many packaging industries and PET manufacturing industries for testing the quality of the pouches and PET bottles. The machine is basically used for checking the formation of bubbles in a product which might be an indication of leaks in the product.

A sample of the product is placed in the working chamber of the machine and then a vacuum is created inside the working chamber. If there are any leaks in the product, bubbles will be formed inside the working chamber, which will be indicated by a change in pressure. This change in pressure can be easily detected by the highly sensitive pressure gauge fitted to the machine. The entire test procedure is extremely simple and can be completed within a very short span of time. This testing machine is very easy to use and comes with a user manual for reference. It is also very compact and can be easily placed on any workbench or table.

Purpose of using Presto vacuum leak tester

The main purpose of using the Presto vacuum leak tester is to ascertain that the package offered to the clients will be free of any leakage and is completely intact. You can easily perform this test to maintain the seal integrity and quality of packages especially when they will be exposed to differential pressure. This test will be done to make sure that seal of the package should be unbroken and perfectly fine and ensuring the leak proofness. This leak test will be performed on the packaging of FMCG products, drugs, and medical and PET products. You can read about how you can easily test your package against vacuum leaks with the use of the Presto vacuum leak tester.

Role of vacuum leak tester in the food packaging industry

A properly sealed package is essential to ensuring that a product retains its freshness and shelf life. This is especially important in perishable items such as salad, baked goods, dairy, and pet food. If there is a leak in the packaging, oxygen will be able to permeate the product and begin or accelerate the decomposition process. In addition, if moisture is able to enter the package, it can cause mold or bacteria to grow, both of which can lead to spoilage. Therefore, it is important to make sure that packages are properly sealed before they are shipped or stored. By taking help from Presto vacuum leak testing equipment you can ensure that your products remain fresh and safe for consumption. This is a globally accepted vacuum leak tester for small pouches.
