Mylar Bags For Food Storage: Guide to Long-Term Food Storage
Food storage is crucial for ensuring a steady supply of safe and nutritious food, especially during emergencies or for long-term planning. Enter Mylar bags: the unsung heroes of food preservation. These mylar bags for food storage are an excellent choice for anyone looking to extend the shelf life of their food while maintaining its quality.
What Are Mylar Bags?
Mylar bags are made from a polyester film known as BoPET (Biaxially-oriented polyethylene terephthalate). This material is renowned for its strength, durability, and ability to block light, moisture, and oxygen. Mylar was first developed in the 1950s by DuPont, and since then, it has become a staple in various industries, including food storage.
Benefits of Using Mylar Bags for Food Storage
Long Shelf Life
One of the primary benefits of Mylar bags is their ability to extend the shelf life of stored food. When properly sealed, these bags can keep food fresh for years, making them ideal for emergency preparedness and long-term storage.
Protection Against Light, Moisture, and Pests
Mylar bags provide a strong barrier against external elements that can degrade food quality. They are excellent at blocking out light, which can cause food to deteriorate. Additionally, they prevent moisture and pests from getting in, ensuring your food remains safe and dry.

Preservation of Nutritional Value
By keeping out air and moisture, Mylar bags help preserve the nutritional value of food. This is particularly important for storing grains, legumes, and other staples that you rely on for daily nutrition.
Types of Mylar Bags
Different Sizes
Mylar bags come in a variety of sizes, from small pouches perfect for snacks to large bags suitable for bulk storage. This variety allows you to choose the right size for your specific needs.
Thickness Variations
The thickness of Mylar bags can vary, typically ranging from 3.5 mils to 7.5 mils. Thicker bags provide better protection but may be more challenging to seal.
Pre-made vs. Custom Sizes
You can purchase pre-made Mylar bags in standard sizes, or you can opt for custom sizes if you have specific storage requirements. Custom-sized bags can be especially useful for unique or irregularly shaped items.
How to Use Mylar Bags for Food Storage
Preparation Steps
Before you start packing, make sure your Mylar bags and the area you’re working in are clean. Gather all necessary materials, including oxygen absorbers and sealing equipment.
Packaging Process
Fill the Mylar bags with your chosen food items, leaving some space at the top for sealing. If you’re using oxygen absorbers, place them on top of the food before sealing the bag.
Sealing Methods
There are several methods for sealing Mylar bags, including heat sealing, vacuum sealing, and using impulse sealers. Each method has its advantages, so choose the one that best fits your needs.
Choosing the Right Mylar Bags
When selecting Mylar bags, consider factors such as size, thickness, and the type of food you plan to store. For example, thicker bags are better for long-term storage of items like rice and beans, while thinner bags might be sufficient for short-term storage of snacks.
Sealing Mylar Bags: Methods and Tools
Heat Sealing
Heat sealing is a popular method for closing Mylar bags. You can use a household iron or a hair straightener for this purpose. Simply run the hot device along the edge of the bag to create a tight seal.
Vacuum Sealing
Vacuum sealing involves removing the air from the bag before sealing it. This method is excellent for preventing oxidation and extending shelf life.
Using Oxygen Absorbers
Oxygen absorbers are small packets that remove oxygen from the sealed environment, further preserving the food inside. They are especially useful for long-term storage.
Mylar Bags vs. Other Storage Options
Comparison with Plastic Containers
While plastic containers are convenient, they do not provide the same level of protection as Mylar bags. Mylar bags are better at blocking light and moisture, making them superior for long-term storage.
Comparison with Glass Jars
Glass jars are great for preserving food, but they are bulky and prone to breaking. Mylar bags, on the other hand, are lightweight, flexible, and easier to store.
Comparison with Vacuum-Sealed Bags
Vacuum-sealed bags offer good protection but can be expensive and less durable than Mylar bags. Mylar bags are also more versatile and can be resealed if needed.
Common Mistakes to Avoid When Using Mylar Bags
Overfilling Bags
Leaving enough space at the top of the bag is crucial for effective sealing. Overfilling can lead to poor seals and compromised food safety.
Improper Sealing
Ensure that the entire edge of the bag is sealed properly. Any gaps can allow air and moisture to enter, spoiling the food inside.
Ignoring Oxygen Absorbers
Forgetting to add oxygen absorbers or using the wrong amount can significantly reduce the shelf life of your stored food. Make sure to include the appropriate number of absorbers based on the size of the bag and the type of food.
Storing Different Types of Food in Mylar Bags
Grains and Legumes
Grains and legumes are ideal candidates for Mylar bag storage. They have low moisture content and, when paired with oxygen absorbers, can last for decades.
Dried Fruits and Vegetables
Dried fruits and vegetables can also be stored in Mylar bags, but they may require additional moisture control methods to prevent spoilage.
Powdered Foods and Spices
Powdered foods and spices are susceptible to moisture and light, making Mylar bags an excellent choice for preserving their flavor and potency.
Long-Term Food Storage: Tips and Tricks
Ideal Storage Conditions
Store Mylar bags in a cool, dark, and dry place to maximize their effectiveness. Avoid areas with fluctuating temperatures or high humidity.
Rotating Stored Food
Practice the “first in, first out” method to ensure that older food is used before newer items. This helps maintain the freshness and quality of your stored food.
Monitoring and Checking Stored Items
Regularly check your stored food for any signs of spoilage or damage to the Mylar bags. This proactive approach can help you address issues before they become major problems.
Environmental Impact and Sustainability
Reusability of Mylar Bags
Mylar bags can be reused if they are carefully opened and not damaged. This reduces waste and makes them an eco-friendly option for food storage.
Eco-Friendly Disposal Methods
If you need to dispose of Mylar bags, look for recycling programs that accept them. Some specialized facilities can handle the material, preventing it from ending up in landfills.
Comparing with Other Storage Methods
When compared to single-use plastic bags or containers, Mylar bags have a lower environmental impact due to their durability and reusability. They also help reduce food waste by extending the shelf life of stored items.
Conclusion
Mylar bags are a fantastic option for anyone looking to preserve their food for the long term. They offer superior protection against the elements, are versatile, and can significantly extend the shelf life of your food. By choosing the right Mylar bags and using them correctly, you can ensure that your food remains fresh, nutritious, and ready to use whenever you need it.
