How Thick Should Mylar Bags Be for Food Storage
For food storage, you’ll want Mylar bags that are at least 5 mil thick to protect against moisture, oxygen, and light. Thicker bags—around 6 to 7 mils—offer better durability, especially for long-term storage or foods with sharp edges like jerky.
If you’re storing lighter, short-term items like herbs, thinner bags can work. Matching your bag thickness to your specific food and storage time helps keep your food fresh longer.
