Vacuum packaging is primarily used to extend the shelf life of perishable foods such as meats and cheeses by reducing atmospheric oxygen and limiting the growth of aerobic bacteria. It is also commonly used to store dry foods over a long period of time, such as cereals, nuts, cured meats, coffee, and potato chips. This form of packaging is becoming increasingly popular in other industries such as electronics and medical for its advantages of providing a clean, dry, and low oxygen environment for sensitive goods.
