Shelf Life of Food Extended to 21 Weeks, Claims Manufacturer

European company says its process completely removes oxygen from food packaging.

France-based Rosas claims it has patented technology that can extend the shelf life of food from 21 days to 21 weeks while saving on packaging materials.

The process, designed for thermoformer machinery, extends shelf life by complete oxygen removal, the company claims.
