We suggest investing in a packaging process that incorporates the use of use MAP (modified atmosphere packaging) technology, such as on-package valves, the go-to option for extending the shelf life of fresh items. Most often used in the coffee industry, these special valves can be added to premade bags or to rollstock film during the packaging process. Many specialty coffee roasters use MAP packaging (link to blog post) to allow for the release of carbon dioxide from the coffee bag without letting any ambient environmental gases or contaminants in. This allows for packaging coffee beans at the height of their freshness, preserving the flavors and quality that consumers desire.
