Mylar packing food for long term storage

Rourke: This post was originally published here on It is just as relevant today.


Storing food continues to be my main priority in gathering survival supplies. Canned goods are the mainstay of much of my stockpile along with some freeze-dried. Over the past few months I have added some additional food via storing them in mylar bags.

Mylar packaging has been around for many years. Used for many different products – mylar has a unique ability to present an oxygen barrier and protect food for extended storage.

So – how do I store food in mylar bags? Typically for preparedness-related food storage – food is placed into the mylar bag, an oxygen absorber is placed in the bag, and then the bag is sealed(using heat). The oxygen absorber will eliminate almost all the oxygen in the bag – thus providing a very long shelf life.

Mylar bags, food, iron, and oxygen absorbers

In the picture above I have my supplies laid out – mylar bags, oxygen absorbers, some spaghetti, and my iron.


Rice is a good candidate for mylar packing

I also had some rice as well to store away.

Simple – fill and add the oxygen absorber

Here I have placed some rice in the mylar and added the oxygen absorber. Next the top of the bag needs to be sealed up.

Note: Yes – a lot more rice can go in this bag.

Using an iron to seal the bag.

Part of the “trick” to sealing the bag is to place it on something – and then run the hot iron over the mylar sealing it. As much as possible should be removed from the bag prior to sealing.  I generally form a 1-2 inch sealed edge along the top. Once sealed – it is good to try to squeeze the bag to make sure there are no leaks.

Bag is sealed.

There are any different sized bags available. I prefer the gallon size.

Here is some spaghetti ready to be stored away.

Above is one of my completed bags. Mark all bags with the date of packaging, contents, and approx amount.

Filling it up – ready when I need it.

Once I have several bags done – I place them in a plastic 5 gallon bucket and place the lid on it. I then mark on the outside the date of packaging and I list the contents as well. Of note I never pack a bucket with all one ingredient. I always mix up the contents – beans, pasta, rice, sugar, salt, etc. Why? In-case I have to pack buckets in a vehicle to “head for the hills” – I want to know that however many buckets I get I will have a variety of food items in each one.

Overall – this method is very expensive. I have some Amazon links embedded in this post showing some of the supplies I have purchased and used myself. Also – there are some good videos on YouTube demonstrating this process.

When stored under the right conditions certain foods can last a very long time.

Better to have it and not need it than to need it and not have it.

  1. My dilemma is that I can’t decide between the ziploc bags and the regular gallon bags. It’s just the two of us now, so I can finally afford to go ahead and purchase. Before now, we went through the food so fast that it wasn’t necessary to use them!

    BTW, if you purchase cereal and such, you can re-use the mylar bags in them.

    • They may seal it if it has a manual seal function. However it won’t create a vacuum so you will still need oxygen absorbers.

  2. JohnP – The vacuum sealer can’t work as far as sucking the air out because the mylar has no ridges. Only Ruffles have ridges. lol. The heat strip on the vac sealer might well seal the bag for you though.

  3. Professional chamber type vacuum sealers work great with mylar. See Vac Master for instance Mylar can be more easily torn than thick plastic bags so if you choose to vacuum seal them, be careful of sharp corners.
