Because the growth and division of microorganisms require the participation of oxygen, the spores and hyphae of microorganisms are strongly inhibited under anoxic conditions. Thereby, the food in the bag is preserved, and the probability of microbial contamination is reduced.

Q:Can food wrap be heated in a microwave oven?
