According to one embodiment the coating includes a hygroscopic polymer matrix, a plasticizer, and a desiccant material selected from calcium chloride, calcium oxide, potassium chloride, magnesium chloride, magnesium sulfate, ammonium chloride, sodium nitrate, citric acid, and tartaric acid, and wherein the amount of plasticizer is from 5 to 20 wt. % with respect to the amount of polymer matrix, and the amount of desiccant material is from 25 to 60 wt. % with respect to the amount of polymer matrix. Also, is provided a process for producing the package.

Abstract: A packaging that generates a protective atmosphere from a chemical reaction that generates carbon dioxide which is triggered by the natural exudate of the packaged product and which extends over time, such as to effectively control the generation of gases inside the packaging and avoiding build-up of exudate in contact with the food product inside said packaging.
