What Is Hermetic Packaging?

Hermetic packaging is a type of packaging in which many of the products at your local supermarket are sealed. Hermetic packaging can seal in the freshness of various consumer goods.

  1. Function

    • Hermetic packaging is what certain products are referring to when they say that they are "hermetically sealed." The function of hermetic packaging is to create a seal that prevents gases and moisture from entering or leaving the product. As a result, the products are completely airtight.

    Types

    • There are several types of hermetic packaging that are used in packaging consumer goods today. Pharmaceuticals and dry food products, like chips and cereals, are vacuum-packed to prevent air and bacteria from entering the package and making the products stale. Moist foods, like soups and fruit juices, are usually sealed in cans instead.

    Benefits

    • There are many benefits to hermetic packaging. Hermetic packaging that prevents the passage of gases and liquids prevent foods and other products from being infected by various types of bacteria. It also seals in the products' freshness, effectively extending their shelf life many times over.
