The Mylar Bags are used to allow these issues to be avoided by providing a protective environment that is airtight. Once you put oxygen absorbers in the bag and close it by heating, the level of oxygen inside the bag decreases significantly. Studies indicate that oxygen absorbers have the ability to lower the oxygen levels in closed bags to less than 0.1% to delay spoilage and reduce insect activity.

• Blocks oxygen and moisture
• Prevents insect contamination
• Protects food from UV light
