Why does Smoked Salmon in a gold foil pouch have such a long shelf-life?
The gold foil pouch or retort pouch, is constructed of a polyester film which is laminated to an aluminum foil with a polypropylene coating. This combination of materials is used for it’s resistance to high temperature and for it’s durability. It also provides a barrier to light, gases, microorganisms and odors. The foil pouch is good for at least 5 years and will preserve the Smoked Salmon within the package as long as the pouch has not been been damaged.
