The industry is increasing its emphasis on:
a. Food safety
c. Shelf life
The use of Modified Atmosphere Packaging (MAP) is one important way the food industry has responded to increased scrutiny of packaging. In fact, MAP is one the fastest growing segments of packaging industry. Exposure of food products to the atmosphere causes the oxidation of the product resulting in major issues for the food industry such as a decrease in shelf live, loss of flavor and
discoloration. MAP works by reducing the amount of oxygen the product is exposed to. This is accomplished by flushing the package with nitrogen or CO2 just prior to sealing – resulting in an internal package environment of less than 0.5% oxygen.
