In today's world, many people are taking proactive steps towards long-term food storage. This can be for a variety of reasons, from prepping for emergencies to simply wanting to ensure a reliable source of food in case of unexpected disruptions. Mylar bags have become a popular choice for long-term food storage due to their unique properties that help extend the shelf life of food.
What are Mylar Bags?
Mylar bags for food storage are metalized polyester pouches made from a combination of polyethylene and aluminum foil. This combination creates a strong, durable barrier that protects food from several threats that can lead to spoilage.
Benefits of Using Mylar Bags for Food Storage
There are several key benefits to using mylar bags for long-term food storage:
- Light Barrier: Mylar is an excellent light barrier. Light exposure can accelerate spoilage in many foods, especially fats and oils. By blocking light, mylar bags help to preserve the nutrients and flavor of your food.
- Oxygen Barrier: The aluminum layer in mylar bags acts as a barrier to oxygen. Oxygen exposure is a major contributor to food spoilage, as it promotes the growth of bacteria and mold. By minimizing oxygen exposure, mylar bags help to slow down the spoilage process.
- Moisture Barrier: Mylar offers some protection against moisture, which can also lead to spoilage. However, it's important to note that mylar bags are not completely waterproof. For optimal moisture protection, it's recommended to combine mylar bags with oxygen absorbers (discussed later).
- Puncture and Tear Resistance: Mylar bags are relatively puncture and tear-resistant, providing an extra layer of protection for your stored food.
- Lightweight and Compact: Mylar bags are lightweight and compact, making them a space-efficient way to store large quantities of food.
What Foods Can Be Stored in Mylar Bags?
A wide variety of dry foods can be stored in mylar bags, including:
- Grains (rice, wheat, beans, pasta)
- Nuts and seeds
- Dried fruits
- Flour
- Sugar
- Salt
- Spices
- Powdered milk
- Dehydrated vegetables and fruits
- Coffee and tea
Not recommended: It's important to note that mylar bags are not suitable for storing all types of food. Foods with high moisture content, such as fresh fruits and vegetables, meat, and dairy products, are not recommended for mylar bag storage. These foods require specific storage methods to prevent spoilage.

Using Mylar Bags Effectively for Food Storage
To get the most out of mylar bags for food storage, follow these steps:
- Choose the Right Size Bags: Mylar bags come in a variety of sizes to accommodate different food types and quantities. Consider how much food you want to store and choose bags that are the right size to minimize air pockets within the bag.
- Use Food-Grade Mylar Bags: Ensure you purchase mylar bags specifically designed for food storage. These bags are made from food-grade materials that are safe for long-term food contact.
- Prepare Your Food: Before storing food in mylar bags, it's crucial to ensure the food is properly dried and free of pests. Most dry foods benefit from being dried to a moisture content of around 10% or less.
- Oxygen Absorbers: For optimal long-term storage, use oxygen absorbers along with mylar bags. Oxygen absorbers remove oxygen from the bag, creating an oxygen-depleted environment that further slows down spoilage. Choose the appropriate size oxygen absorber based on the volume of your mylar bag and the food you are storing.
- Heat Sealing: Once you've added your food and oxygen absorbers, use a heat sealer to create an airtight seal on the mylar bag. This will prevent air from entering the bag and compromising the storage environment. If you don't have a heat sealer, some mylar bags come with resealable closures, but these may not be as effective for long-term storage.
Storing Your Mylar Bags
Once your mylar bags are sealed, store them in a cool, dark, and dry location. A basement, pantry, or other climate-controlled area is ideal. Avoid storing mylar bags in areas with extreme temperatures or high humidity.
Safety Considerations
Mylar bags themselves are generally safe for food storage. However, it's important to remember that mylar is not a replacement for proper food handling practices. Always ensure your food is properly dried and free of contaminants before storing it in mylar bags.
Conclusion
Mylar bags offer a valuable tool for long-term food storage. By utilizing their light, oxygen, and moisture barrier properties, you can significantly extend the shelf life of your dry food
