Mylar Bags: A Modern Solution for Food Storage

As we all know, storing food for long periods of time is important for emergencies and for convenience. However, traditional food storage methods such as canning and freezing can be time-consuming, expensive and can take up valuable space in the home. Fortunately, there is a modern solution that is growing in popularity among survivalists, preppers, and normal folks alike: mylar bag. In this blog post, we will explore what Mylar bags are, why they are a great choice for food storage, and how to use them effectively.

What are Mylar bags?

Mylar bags are made from a metallized polyester film that is incredibly strong and resistant to punctures, tears, and moisture. They were developed by NASA in the 1950s to protect spacecraft from extreme temperatures and radiation. They are now used in many industries, including food storage, because of their durability and effectiveness in protecting goods from the elements.

Mylar bags are a type of polyester film that is made using stretched polyethylene terephthalate (PET). They were first developed by DuPont in the 1950s for use in high-temperature applications. Mylar bags are tear-resistant, lightweight, and have excellent barrier properties that make them ideal for food storage. They help to protect your food from oxygen, moisture, and sunlight, all of which can spoil your food. They’re an excellent choice for long-term food storage.

Why are Mylar bags a great choice for food storage?

Mylar bags offer several advantages over traditional methods. Firstly, they are lightweight and compact, taking up much less space than jars or cans. This makes them ideal for people who live in small homes, apartments, or those who need to store food in a tight space. Secondly, they are airtight and offer excellent protection against moisture, pests, and oxidation. This is crucial for long-term food storage because it prevents food from spoiling and reduces the risk of bacterial growth. Lastly, Mylar bags are affordable. They are relatively inexpensive compared to other food storage options, making them accessible to everyone.

How to use Mylar bags effectively

Mylar bags are incredibly easy to use and can be filled with a variety of foods including dried grains, beans, and powdered milk. Here are some tips to help you use them effectively:

Choose the right bag size: always select a bag that is appropriately sized for the amount of food you want to store. Overfilling a bag can lead to punctures and tears, while under-filled bags will take up too much space.

Remove as much air as possible: air trapped in the bag can lead to oxidation and spoilage, so it is essential to remove as much air as possible. You can do this using a vacuum sealer or by pressing down on the bag before sealing it.

Store in a cool, dry place: Mylar bags are incredibly durable but they will last longer if stored in a cool, dry place such as a pantry or basement.

Label bags with date and contents: it is essential to label each bag with the date of filling and the contents of the bag. This will help you keep track of what you have stored and when it was sealed.

Food storage has always been vital, especially in today’s society where everything is easily accessible. Being able to store food for a long time without it losing its quality is essential in case of emergencies. A modern solution for food storage is using mylar bags. If you’re not familiar with mylar bags, this blog post will help you understand what they are, why they’re so useful, and how you can use them for food storage.

Why are mylar bags so useful for food storage?

Mylar bags are incredibly useful for food storage because of their barrier properties. They are moisture resistant, which helps keep your food fresh for an extended period of time. They’re also oxygen free, meaning that they keep your food from being exposed to air, thus preventing it from spoiling. They are also heat-resistant, which means they can be used for hot or cold storage. Finally, mylar bags are affordable. They’re a low-cost solution for food storage that can help you save money by allowing you to purchase food in bulk.

How can you use mylar bags for food storage?

When using mylar bags for food storage, you want to ensure that you’re using the right size and thickness. You don’t want to use a bag that’s too small for what you’re storing, or you’ll risk damaging the bag. The thickness of the bag is also important, as it determines how long it can store your food. Most mylar bags come in thicknesses ranging from 3.5 mils up to 7 mils. If you’re storing food for three months or less, a 3.5 mils bag will work, but if you’re storing it for longer periods, you may want to consider a thicker bag.

Another important step when using mylar bags for food storage is to add an oxygen absorber. Oxygen absorbers are small packets that remove oxygen from inside the bags, ensuring your food stays fresh and doesn’t spoil. You can purchase oxygen absorbers online, and they’re typically sold in packets of 50, 100, or more. The number of oxygen absorbers you’ll need will depend on the size of your bag and what you’re storing.


Mylar bags are becoming a popular choice for food storage because of their durability and affordability. They offer excellent protection against moisture, pests and bacterial growth, and are ideal for people with limited space. By following some straightforward tips, anyone can use Mylar bags to store food long-term. So if you’re looking for an effective and budget-friendly way to store bulk foods or preserve your harvest, give Mylar bags a try!

Mylar bags are an excellent solution for food storage. They’re affordable, moisture-resistant, heat-resistant, and oxygen-free, making them ideal for long-term storage. When using mylar bags for food storage, ensure you’re using the right size and thickness, and consider adding an oxygen absorber to keep your food fresh. With mylar bags, you can purchase food in bulk and store it for months or even years. Investing in mylar bags is a smart move for anyone looking to ensure they have an emergency food supply or just to save money by buying food in bulk.
