Container Closure Integrity Testing (CCIT) in the pharmaceutical industry is such an important piece of the packaging puzzle, that more and more regulatory agencies around the globe are beginning to draft specific requirements for manufacturers. However, an absolute truth in the CCIT space is that one single inspection technology cannot be used for every type of pharmaceutical product.You should always weigh the various factors to determine the ideal inspection methodology. So how does one determine the best inspection method for their particular product? Feasibility testing!
High Voltage Leak Detection (HVLD), a technology first applied to pharmaceutical manufacturing in the 1970s, does not destructive to packaging components or cause the loss of good product like other inspection methods. HVLD is capable of handling any product as long as the container is made of electrically insulated material and the product contains an electrically conductive solution. In this article you will learn more about other packaging applications that can be inspected with HVLD.
In pharmaceutical and food packaging, there are multiple methods widely used to test if these container-closure systems pose any risk of leakage from pinholes, cracks, or defective seals. These tests range from vacuum or pressure decay tests, to submerging the entire container into a dye solution under pressure and visually inspecting the container for the presence of dye, to more advanced vision systems that inspect for certain defects in the container. Let’s compare two of the more common methods: high voltage leak detection (HVLD) and vacuum decay.
It is understood that no matter how carefully a product has been prepared, it would still be unsafe for human use if the container has a pinhole, a crack or a defective seal. There are a variety of methods widely used in the detection of pinholes, cracks and defective seals in containers however a majority are destructive causing the loss of good product and packaging components. Read more to learn why the High Voltage Leak Detection (HVLD) system is totally free from these shortcomings and has additional advantages for ensuring seal integrity.
