In this guide, you’ll discover everything you need to know about Mylar bags for long-term food storage—from their benefits to practical tips on sealing and storing like a pro. Let’s dive in and unlock the secrets to keeping your food fresh!
What Are Mylar Food Storage Bags
Mylar food storage bags are a popular choice for preserving and storing food safely over long periods. These bags are made from Mylar film, a strong polyester film known for its excellent protective properties.
Material Composition and What Makes Mylar Film Special
Mylar film is essentially biaxially-oriented polyethylene terephthalate (BoPET). It’s layered with metals, usually aluminum, which gives the bags a shiny, reflective surface inside and out. This metal layer is what makes Mylar bags stand out compared to regular plastic bags.
Key Characteristics of Mylar Food Storage Bags
- Strength and Durability: Mylar bags are tear-resistant and sturdy, making them perfect for handling rough storage conditions.
- Moisture Barrier: They are nearly impermeable to water vapor, which keeps food dry and prevents mold or spoilage.
- Oxygen Barrier: Mylar blocks oxygen effectively, which is crucial because oxygen exposure can spoil many foods or cause rancidity in nuts and powders.
- Light Barrier: The reflective metallic layer protects contents from harmful light that could degrade food quality over time.
These strong barrier properties make Mylar bags ideal for long-term food storage—especially for dry and freeze-dried foods—while keeping them fresh, safe, and free from pests. They’re also available in food-grade Mylar bags, ensuring they meet safety standards for storing edibles.
In short, Mylar food storage bags combine strength, durability, and multi-layered protection that ordinary plastic bags or containers can’t match, which is why they’ve become a favorite for emergency preparedness, bulk food storage, and everyday kitchen use.
Benefits of Using Mylar Food Storage Bags for Long Term Food Storage
Using Mylar food storage bags comes with several clear advantages, especially for those serious about preserving food quality and shelf life. Here’s why these food-grade Mylar bags are a smart choice for storing dry and freeze-dried foods.
Extended Shelf Life for Dry and Freeze Dried Foods
One of the biggest benefits of Mylar bags is their ability to dramatically extend the shelf life of your stored food. When combined with oxygen absorbers, Mylar creates a nearly airtight environment that keeps out the oxygen responsible for spoilage. This makes them ideal for:
- Grains, beans, rice, and nuts
- Freeze-dried ingredients and emergency food supplies
These bags can keep food fresh for years, far longer than traditional plastic bags or containers, making them essential for long term food storage.
Superior Protection Against Oxygen Moisture Light and Pests
Food spoils not just from oxygen but also moisture, light, and insects. Mylar bags have a unique multi-layered barrier that blocks:
- Oxygen — slowing oxidation and rancidity
- Moisture — preventing mold and spoilage
- Light — protecting nutrients and color from degradation
- Pests — sealing out insects like weevils
This combination means your food stays dry, pest-free, and nutrient-rich, especially when stored in a cool, dark place.
Versatility from Home Kitchens to Emergency Preparedness and Commercial Use
Whether you’re storing bulk pantry staples at home or prepping emergency food kits, Mylar bags offer unmatched versatility. Home cooks love how easy it is to portion and seal dry ingredients. Emergency preppers value the reliability and shelf life for freeze-dried meals. Businesses appreciate customizable sizes and branding options for commercial food packaging.
Cost Effectiveness and Sustainability
While Mylar bags may have a higher upfront cost compared to standard plastic bags, their long-term savings are significant:
- Minimized food waste due to extended freshness
- Reusability with proper care, reducing repeated purchases
- Lightweight and space-saving design cuts storage and shipping expenses
Plus, many food-grade Mylar bags are recyclable and help reduce reliance on single-use plastics, making them a more sustainable option for households focused on eco-friendly storage solutions.
Using food-grade Mylar bags is a smart move whether you’re storing bulk food for daily use, prepping emergency meals, or running a small food business. Their durability, protection, and cost effectiveness deliver lasting value that other storage options often can’t match.
Types and Sizes of Mylar Food Storage Bags Available
When choosing Mylar food storage bags, it’s important to know the different types, sizes, and features you can get. Whether you’re storing small batches or bulk food supplies, there’s a Mylar bag to fit your needs.
Standard Sizes and Customization Options
Mylar bags come in a wide range of sizes, typically from small 1-pint (about 16 oz) bags up to large 5-gallon (about 640 oz) bags. Here’s a quick guide:
- Small bags (quart or pint size) – Great for nuts, seeds, or smaller portions of freeze-dried foods.
- Medium bags (gallon size) – Perfect for grains, beans, rice, and powders.
- Large bags (2-5 gallons) – Best suited for bulk storage and long-term emergency food supplies.
For those who need something specific, many suppliers offer custom-sized Mylar bags. This means you can get exact dimensions, tailored thickness, or even printed branding if you are a business or bulk buyer.
Thickness and Quality Grades for Different Uses
Bag thickness matters a lot in food storage. It’s usually measured in mils, where higher mil numbers mean thicker, stronger bags:
- 4 to 5 mil thickness – Used for standard, everyday food storage.
- 7 mil and above – Recommended for long-term storage or heavy-duty use.
- 10 mil+ thickness – For commercial or extreme conditions where maximum protection is required.
Thicker bags offer better moisture and oxygen barriers, increasing shelf life especially for sensitive foods.
Features of Mylar Food Storage Bags
Mylar bags don’t just come plain—they include handy features to suit your storage style:
- Resealable tops – Zip locks or slider seals make it easy to open and close bags without extra tools.
- Pre-printed bags – Some bags come with labels or branding already printed, useful for businesses or organized storage.
- Plain Mylar bags – These are simple, unprinted, and versatile for any kind of use or labeling.
- Flat bottom or gusseted bags – Provides stability for standing in cupboards or shelves.
These features help keep your food fresh while making access and organization easier, especially for home kitchens, camping setups, or emergency preparedness.
Knowing the types, sizes, and features of Mylar bags helps make smarter choices for your food storage needs. Whether you want standard or custom, thin or thick, resealable or plain, there’s a Mylar bag that fits the bill for keeping your food safe and fresh.
How to Use Mylar Food Storage Bags Effectively for Long Term Food Storage
Using Mylar food storage bags the right way is key to keeping your food fresh and safe for months or even years. Here’s how to get the best results, whether you’re storing grains, freeze dried foods, or emergency supplies.
Preparing Food for Mylar Storage
- Dry your food well before packing. Foods like grains, beans, and powders should be completely dry to avoid mold growth.
- For freeze dried or dehydrated foods, make sure they’re properly processed to remove moisture.
- You can pack bulk foods straight into Mylar bags or use smaller bags for portion control.
Proper Sealing Techniques
Sealing your Mylar bags correctly is crucial to maintaining that strong moisture and oxygen barrier. Here are two common methods:
- Heat sealing: Use a commercial heat sealer designed for Mylar bags. This gives the best, airtight seal for long term storage.
- Iron sealing: If you don’t have a heat sealer, a household iron on low to medium heat can work. Place a thin cloth over the bag edge then run the iron steadily to seal.
Adding Oxygen Absorbers Why and How
Oxygen absorbers are a must-have for Mylar bags used in long term food storage. Here’s why:
- They remove oxygen inside the bag, which slows down spoilage and insect infestation.
- For best results, add the right size oxygen absorber for your bag volume. As a rule, use a 1000cc oxygen absorber for a 1-gallon bag.
- Place the oxygen absorber inside the bag just before sealing to avoid premature activation.
Labeling and Storage Tips
Keeping track of what’s inside and how long it’s been stored is easy with proper labeling:
- Write the food type, packing date, and any special notes on the bag with a permanent marker.
- Store Mylar bags in a cool, dark place to protect against light and temperature swings.
- Avoid exposure to sunlight or heat sources, which can degrade the bag material over time.
By following these tips, you’ll make sure your Mylar food storage bags do their job, keeping your food fresh, safe, and ready whenever you need it.
What Foods Can Be Stored in Mylar Food Storage Bags
Mylar food storage bags are incredibly versatile and great for storing a wide range of foods, especially those prone to spoilage from moisture, oxygen, or light. Here’s a quick rundown of the best types of foods to store in these bags:
Dry Foods That Store Well in Mylar Bags

Mylar Bags vs Other Food Storage Options Comparing Plastic Bags Glass Jars and Vacuum Sealing
When it comes to long-term food storage, Mylar food storage bags stand out among common options like plastic bags, glass jars, and vacuum sealing. Here’s how they stack up:
Mylar Bags Compared to Plastic Bags
- Better Barrier Protection: Unlike standard plastic bags, Mylar bags are made from a special polyester film that blocks out moisture, oxygen, and light much more effectively. This helps extend the shelf life of dry goods and freeze-dried foods significantly.
- Stronger and More Durable: Mylar bags resist punctures and tears better, making them ideal for long-term storage.
- Limitations: Regular plastic bags are cheaper and more convenient for short-term use but lack the durability and protective barrier needed for extended storage.
Mylar Bags Compared to Glass Jars
- Lightweight and Space Efficient: Mylar bags are flexible and take up much less space than bulky glass jars, which is great for people with limited pantry room.
- Superior Barrier to Oxygen and Moisture: While glass jars provide an excellent air-tight seal, Mylar bags with oxygen absorbers offer comparable protection for dried foods and don’t break when dropped.
- Limitations: Glass jars allow easy resealing and visibility of contents, which Mylar bags often lack unless resealable options are purchased.
Mylar Bags Compared to Vacuum Sealing
- Better Light and Moisture Protection: Vacuum sealing removes air, slowing spoilage but typically uses plastic bags that let in light and moisture over time. Mylar bags block both better.
- Greater Shelf Life: Using vacuum sealing alone is great for short to mid-term storage, but for emergency food storage or bulk dry goods, Mylar bags with oxygen absorbers are preferred.
- Limitations: Vacuum sealers require machines and accessories, adding cost and complexity, whereas simple heat sealing or ironing works fine for Mylar bags.
Advantages of Mylar Food Storage Bags
- Long Shelf Life: Mylar bags help keep food fresh and safe for years when used properly.
- Moisture and Oxygen Barrier: Excellent at protecting against spoilage, pests, and degradation.
- Cost-Effective and Lightweight: More affordable and easier to store than glass jars or large vacuum-sealed containers.
- Versatile: Works for everything from emergency supplies to everyday pantry storage.
Possible Limitations
- Not Reusable Without Extra Care: Most Mylar bags are designed for single use after heat or iron sealing.
- Visibility: Unless purchasing clear or printed Mylar bags, you can’t see what’s inside without labeling.
- Needs Proper Sealing Tools: Heat sealing is required to ensure airtight protection, which may be a learning curve for some.
Mylar bags offer a durable, reliable, and affordable solution for long-term food storage that combines many benefits of other storage methods while minimizing their downsides. For those looking to maximize shelf life and protect food quality, especially for emergency preparedness or bulk storage, Mylar bags are a smart choice.
