When it comes to long-term food storage, Mylar bags are a game-changer. But how long can food last when sealed inside one? Let’s explore.
Mylar bags are known for keeping food fresh for months or even years. The key factors like air, light, and moisture control play a big role in their effectiveness.
Ready to discover how to make your food last longer? Let’s dive in.
How long do Mylar bags keep food fresh?
Mylar bags are great for keeping food fresh, but exactly how long can they preserve your items?
Mylar bags can keep food fresh for up to 25 years, depending on the type of food, storage conditions, and whether you add oxygen absorbers.
When you seal food in Mylar bags, the lack of air and moisture1 significantly slows down spoilage. Adding oxygen absorbers will further extend the shelf life2 by removing the oxygen that causes oxidation. For example, dehydrated meals can last up to 25 years in sealed Mylar bags, while items like pasta or rice can last for 10 to 20 years. However, this is based on optimal conditions: cool, dry, and dark storage places.
What foods are best for Mylar bags?
Not all foods are suitable for Mylar bag storage. Some foods do better than others.
Foods that are dehydrated, freeze-dried, or low in moisture are ideal for Mylar bags, as these bags help preserve their freshness by blocking out light, air, and moisture.
When you store foods like dried fruits, grains, and dehydrated meats, Mylar bags work wonders by sealing in nutrients and preventing mold growth. For example, you can store powdered milk, pasta, beans, or oats in Mylar bags for extended periods without worrying about them spoiling.
What foods should not be stored in Mylar bags?
While Mylar bags are fantastic for many types of food, they’re not perfect for everything.
High-moisture foods like fresh fruits, vegetables, and canned goods shouldn’t be stored in Mylar bags. The moisture will create a perfect environment for mold growth.
Moisture is the enemy when it comes to Mylar bags. If you try to store things like fresh tomatoes or cucumbers in them, the moisture trapped inside will cause your food to spoil quicker than you might expect. These bags are best for dry, non-perishable goods.
How thick should Mylar bags be for long-term food storage?
The thickness of Mylar bags matters when it comes to ensuring long-term preservation.
For long-term food storage, it’s recommended to use Mylar bags that are at least 5 mil thick, as this thickness provides a sturdy barrier against light, moisture, and air.
Thicker Mylar bags are more durable and less likely to tear, keeping your food safe and secure. Most people use 5 mil bags for long-term storage, but if you’re storing items for decades, 7 mil bags are an even better choice for durability. They can withstand rough handling and offer extra protection.
| Bag Thickness | Recommended Use | Benefits |
|---|---|---|
| 5 mil | Ideal for most foods | Provides strong barrier against moisture, light, and air |
| 7 mil | Best for foods stored for decades | Offers extra durability for long-term storage |
| 3 mil | Suitable for short-term storage | Good for light-duty uses or shorter storage durations |
Conclusion
Mylar bags are fantastic for preserving food for years. With proper sealing and storage, your food can stay fresh for decades.
