The food which is packed is actually not vacuum packed there is a gas know as nitrogen filled inside it the pack contains this gas so that the food material does not get spoiled in same condition if the food is kept in the open air the bacteria and pathogen would attack those food stuff and can contaminate the food so thus by using nitrogen the food material is packed hope it helps us. ..!!
