Tracer Gas for Package Integrity and Testing

Ensuring the reliability of packaging stands as a critical factor in managing sterile products, effectively safeguarding both the product itself and the surrounding environment. This principle holds true across a broad spectrum of items, ranging from snack bags to beverage cans, where the primary objective revolves around identifying any potential instances of air leakage during the packaging phase.

In a more specific context, the utilization of protective gas environments formed by a mix of different gases (referred to as Modified Packaging Atmospheres or MAP) significantly contributes to prolonging the shelf life of perishable commodities. However, the effectiveness of this approach hinges on the consistent maintenance of gas concentrations throughout the product's designated shelf life.

Employing tracer gas offers a technique for evaluating the soundness of packaging, effectively preventing edibles from coming into contact with the external atmosphere and thereby upholding the preservation of their intended shelf life.

The process of tracer gas leak detection operates by generating a pressure contrast between the interior and exterior of the tested object. Within this procedure, the tracer gas—frequently carbon dioxide (CO2) or helium—is allowed to escape from the packaging through any potential leaks, subsequently leading to an observable shift in partial pressure within the testing chamber.

Helium gas is favored due to its minute molecular size, enabling the identification of even minor instances of leakage and thereby ensuring a heightened sensitivity in the testing process.
