best mylar bags

When it comes to long-term food storage, Mylar bags have become an essential tool. But what makes them so special? And why should you consider using them for your food storage needs? In this guide, we’ll explore everything you need to know about best Mylar bags, from their origins to their best uses, ensuring your food stays fresh and safe for years to come.

History of Mylar Bags

Origin and Development

Mylar, a trademarked product of DuPont, was first developed in the 1950s. Originally used for industrial applications due to its strength and durability, Mylar quickly found its way into the food storage industry. Its ability to provide an excellent barrier against oxygen, light, and moisture made it a perfect candidate for preserving food.

Evolution in Food Storage

Over the decades, Mylar bags have evolved from simple storage solutions to sophisticated tools for preppers and homemakers alike. Innovations such as zipper seals and gusseted designs have made these bags more user-friendly and versatile.

Why Choose Best Mylar Bags for Food Storage?

Superior Oxygen Barrier

One of the primary reasons to choose Mylar bags is their exceptional ability to block oxygen. Oxygen is a major culprit in food spoilage, leading to oxidation and the growth of bacteria and mold. Mylar bags, combined with oxygen absorbers, create an oxygen-free environment that significantly extends the shelf life of your food.

Light and Moisture Protection

In addition to blocking oxygen, Mylar bags also protect against light and moisture, two other major factors that contribute to food degradation. The reflective surface of Mylar blocks out light, while the material itself is impervious to moisture, keeping your food dry and safe.

Durability and Flexibility

Mylar bags are incredibly durable, able to withstand rough handling and heavy loads. Despite their strength, they are also flexible, making them easy to store in various spaces. This combination of durability and flexibility makes them ideal for both everyday use and emergency preparedness.

Types of Best Mylar Bags

Standard Mylar Bags

These are the most common type of Mylar bags, used for a wide range of storage needs. They come in various sizes and thicknesses, suitable for different types of food and storage durations.

Zipper Mylar Bags

Zipper Mylar bags offer the convenience of resealability. They are perfect for foods that you access frequently, allowing you to open and close the bag without compromising the integrity of the remaining contents.

Gusseted Mylar Bags

Gusseted Mylar bags are designed with expandable sides or bottoms, providing extra space and making them ideal for bulkier items. They can stand upright, making them easier to organize and store.

Vacuum-Sealable Mylar Bags

These bags are designed to be used with vacuum sealers, providing an additional layer of protection by removing all air from the bag. This is particularly useful for long-term storage of sensitive items like dehydrated and freeze-dried foods.

Choosing the Right Thickness

Thin (3.5 mil)

Thin Mylar bags are suitable for short-term storage or items that will be consumed within a year. They are less expensive but provide less protection than thicker bags.

Medium (5 mil)

Medium-thickness bags offer a good balance between cost and protection. They are ideal for most long-term storage needs, providing excellent durability and barrier properties.

Heavy-Duty (7 mil and above)

For maximum protection, heavy-duty Mylar bags are the way to go. They are more resistant to punctures and tears, making them perfect for storing large quantities of food or items that will be stored for many years.

Common Mistakes to Avoid

Overfilling the Bags

Overfilling can prevent proper sealing and compromise the effectiveness of the oxygen absorbers. Always leave enough space at the top.

Incorrect Sealing

Ensure that the seal is airtight. A poor seal can let in air and moisture, leading to spoilage.

Ignoring Storage Conditions

Improper storage conditions can degrade the bags and the food inside. Always store in a controlled environment to maintain the quality of your stored food.

How to Seal Best Mylar Bags

Iron Method

The iron method involves using a household iron to seal the Mylar bag. Place a piece of wood or a thick towel on a hard surface, lay the top of the bag on it, and press the iron along the edge to create a seal.

Impulse Sealer Method

An impulse sealer is a more professional option, providing a quick and reliable seal. Simply place the edge of the bag in the sealer and press down for a few seconds.

Storing Different Types of Food

Grains and Rice

Grains and rice store exceptionally well in Mylar bags, often lasting 20 years or more when packed properly.

Beans and Legumes

Beans and legumes are another great option for Mylar storage, maintaining their nutritional value and taste over long periods.

Freeze-Dried Foods

Freeze-dried foods have an exceptionally long shelf life, often exceeding 25 years, making them ideal for Mylar bag storage.

Snacks and Treats

While not typically stored long-term, snacks and treats can also benefit from Mylar storage, keeping them fresh and tasty.

Environmental Impact of Mylar Bags

Recycling Options

While not all Mylar bags are recyclable, some programs do accept them. Check with your local recycling facility for specific guidelines.

Sustainable Practices

To minimize environmental impact, consider reusing Mylar bags whenever possible and choose environmentally friendly storage practices.


Best Mylar bags offer a reliable, effective solution for long-term food storage. Their superior barrier properties, combined with their durability and versatility, make them an essential tool for anyone looking to preserve food for the future. Whether you’re preparing for emergencies or simply looking to extend the shelf life of your pantry staples, Mylar bags are a smart investment.


How do I know which thickness of Mylar bag to use?

The thickness you choose depends on your storage needs. Thin bags (3.5 mil) are good for short-term storage, medium bags (5 mil) are ideal for most long-term storage, and heavy-duty bags (7 mil and above) offer maximum protection for the longest storage durations.

Can I use Mylar bags without oxygen absorbers?

While you can use Mylar bags without oxygen absorbers, they won’t provide the same level of protection. Oxygen absorbers are essential for removing residual oxygen, which is crucial for preventing spoilage and extending shelf life.

How do I properly label Mylar bags?

Use a permanent marker to label each bag with the contents and the date of packing. This helps you keep track of your food inventory and ensures you use older items first.

Are Mylar bags rodent-proof?

Mylar bags themselves are not rodent-proof. For additional protection, store them in a sturdy container or bucket with a tight-fitting lid to keep pests out.

What foods should not be stored in Mylar bags?

Avoid storing foods with high moisture content or those that require refrigeration in Mylar bags. Fresh produce, meats, and dairy products are not suitable for Mylar bag storage.
