Using Mylar Bags for Food Storage

Using Mylar Bags for Food Storage


Hi it’s Jaime from Guildbrook Farm here to talk about mylar bags. I’m going to tell you what I use them for, why use them and what type that I buy. Mylar bags are foil packets that are used for long-term food preservation so food preservation longer than a year and what they do is they help to protect against moisture from damaging your food from bugs from hatching and also from nutrient loss so the opacity of the bags that helps prevent sunlight from coming in and destroying a vitamins such as vitamin A and vitamin C there are several types of mylar bags this is a one-gallon mylar bag that has a ziplock on it for if you open it up and you just want to store it on your shelf and this is a 5-gallon mylar bag that does not have a ziplock these are reusable once you use them once you open them up you can save the bags and then reseal them and i have several here that’s probably going to use again these ones has the ziplock on them because i can’t iron over the ziplock I’ll probably just cut this part off and then I’ll seal right here and then as i continue to use these bags I’ll cut the part off that i use and keep working my way down until it’s just impractical to use this bag anymore when it comes to buying mylar bags it doesn’t matter what style you buy but what is really important is the thickness of the bag i would not go with anything less than a five mil bags the reason for that is because anything thinner than us if you hold it up to the light you can see through it and that’s what’s going to cause your nutrient loss so whatever style mylar bag buy make sure you always get at least five mil now mylar bags are used in conjunction in most cases they’re using conjunction with what’s called an oxygen absorber these are thrown into the bag and they remove the oxygen oxygen is what causes well first of all moisture but also causes bugs the hatch or it allows bugs to hatch by removing that oxygen you decrease your chance of bugs hatching yes they can still hatch but it will definitely decrease your chances of bugs hatching. When it comes to bugs whether you like it or not all your food contains bugs. Canned mushrooms have a certain percentage of maggots that they’re allowed per can your potato chips that you eat all kinds of bug parts that are allowed in each bag of potato chips and when it comes to things like flours and grains they are allowed a certain percentage of not only rat feces, mouse feces and bug parts but also eggs which can hatch. Now typically these don’t really hatch within a year but given the right conditions it’s possible that can and for that that’s the reason why you want you use a mylar bag removing the oxygen prevents them from hatching. So what I have here and I just picked up some bulk food I have 50 pounds of gluten-free rolled oats and I have 75 pounds of Navy beans now if I were going to use this within the course of a year would not need to use mylar bags but because i already have some oats that I’m working through right now and it’s possible well actually both of these it’s possible that they’re going to last longer than a year i’m going to not take any chances and i’m going to preserve them in mylar bags. Now there are other options if you don’t want to use mylar bags for protection against food for short term bug protection you can throw some bay leaves into your your food which helps deter bugs some people use diatomaceous earth by mixing it in their food which which I do not do and for long-term bug protection some people freeze their food one option might be to put your food outside on three days when it’s freezing you have to freeze the food for at least 3 days in order to kill most bugs and then again using the mylar bags with the oxygen absorber now there are some foods that you cannot use oxygen absorbers on those would be such as your oily foods such as nuts and your sugars if you put an oxygen absorber in with sugar it’ll turn it hard as a brick and it’ll give it a weird taste so if you’re storing sugar you can store it in the mylar bag but you cannot use the oxygen absorber for that. Now oyxgen absorbers come in several different sizes this is a 2000cc and this is the 500cc I have some believe these are 100 in the jar the size of your oxygen absorber is dependent on the size of your bag and what you’re storing so items that are maybe more dense like your grain would require less oxygen absorbers items like your beans which have a lot of air because they’re not as dense would require more oxygen absorbers there are a lot of charts online and tell you what size oxygen absorber to use with what size bag and what type of product the one that I use is US Emergency Supply it has a really good site that tells you what size oxygen absorber to use for what size bag and for what product ok so let’s get started we’re going to bag these up now one thing when it comes to oxygen absorbers soon as I open this bag these things are going to start sucking up oxygen you can tell from the little eye that is pink that these are good to go once this eye turn blue these oxygen absorbers are no longer good any more now it’s very possible that i will not use all these oxygen absorbers for all the products that i have here if that’s the case one thing you can do is you can throw them very very quickly into a mason jar pop the lid on real quick and they will seal so these you can see the eye is still pink I threw that in there it will probably good for another use if you have any extras you can do that with that ok so normally when filling up a 5-gallon mylar bag we would stick this inside of a five-gallon bucket and the 5 gallon bucket would offer some support for the bag but I am fresh out of 5 gallon buckets so we’re going to see if we can make this work by propping it up in here because this is where my store them until I get more five-gallon buckets alright we’re gonna start scoopin you’re going to want to shake these down get out as much air as possible in packing that way your oxygen absorbers have less work to do this bag isn’t quite as full as this bag In order to reduce the amount of oxygen in here I’m going to trim some off the top again the least amount of empty space you have the better chance of the oxygen absorbers have to work so we’re just going to trim a little bit off alright let’s do our beans I’m going to start off by recycling some of these old bags and I’m going to cut off the ziplock so that there is room to seal the bags So just to show you here is a new bag you can see there’s room appear above the ziplock to seal the bag but because these are already used that cut that part off so in order to have room to seal it I need to cut off the ziplock. So the ziplock is really only good for one time use. so I actually forgot i have some half gallon bags so the smaller ones are the half gallon bags, these are the one gallons and these are my five gallon bags so in order to tell you what size CC oxygen absorber I need you want to look at a chart like this US Emergency Supply and you can see where they have the container type the type of food was a wheat flour grain or rice or whether it’s pasta or beans which are less dense. And these top ones are for buckets you want to go down here to the mylar bag so the five-gallon mylar bags are going to require about 2000cc for my oats for the one gallons over here beans we need about a thousand for my half-gallon we also need a thousand so a thousand in the small ones and 2000 in the big ones, two thousand in the big ones. Ok so I have 500 CC oxygen absorbers here these bags all require a thousand so will put two in each one of these bags and the five gallons requires 2000cc so we’re gonna put four oxygen absorbers in these bags before we open this bag up, we have to do is really quickly because these are going to start absorbing oxygen i need to have a jar ready with a lid so if there’s any leftover i’m going to throw this jar and put the lid on super quick and we have to have irons now what’s going to seal these bags is going to be an iron. They make irons specifically for mylar bags but you can use a regular old clothes iron or one of our viewers suggested using a flat iron and since we don’t use this puppy anymore, might as well put it to some good use so we’re going to give it a try this time ok so this is going to be really super quick, let’s get started That sealed up pretty nice. It helps if you have a partner but mine is a little busy right now This actually works really well. It’s a whole lot better than you have to use a clothes iron With a clothes iron, you would have to lay this down something flat we have boards here in case this didn’t work and it works really well and one thing to note i have this iron set on 350 degrees and it seems to seal pretty well we did do a little test before we got started you’re going to want to make sure that you test it so that it’s not too hot and doesn’t melt the bag and also that it’s hot enough another thing I got so excited showing you guys how to do these bags that i forgot to write what they were on the bags usually I write it before I write out what the product is before I fill the bag so i got like one mystery bag over here. It ought to be interesting to see what that is we open it up they’re going to be navy beans or pinto beans That works rather nice if you had to use the iron you would need a board like this and you have to fold it down over this and then use the iron on it. I actually like this a lot better and really glad that we got this suggested to us. This works fantastic like I said now i have to write the names of what these are before you pack your bags write what it is and write the date on it. it’s a lot easier than writing it on afterwards because you don’t know what’s what these are Pinto supposedly and these are navy ok so now all of the bags were sealed and labeled properly after about 24 hours to up to about a week it’s going to take that long for the oxygen to be removed from the bags you’ll start to notice that the bags shrink up like this and most cases but in some cases like in this quinoa bag, it still looks like there’s air in there and there in there in there because the oxygen absorbers remove the oxygen not the air so there’s still nitrogen in there and it’s very possible that they can look a little loose like this but it doesn’t mean those bad it’s okay now how long do these last people have reported that mylar bags can be stored for up to 40 years or longer really as long as you open it up and there’s no bugs in it and it looks good and smells good you can eat it now what do we do with these bag now well these should not be stored on a shelf just like this because it’s very easy for a mouse or rodent to eat through this bag they should be stored in some sort of bucket or container you don’t need to use a food-grade bucket if these are already in food grade mylar bags you can just get into any bucket. For our oats, I ran out of 5 gallon bucket so I’m just going to store it right here in this plastic bin with a lid on it and for my beans i have the same buckets but a little bit smaller that i’m going to store them in so again mylar bags they’re really good for dried goods such as pasta, whole grains anything along that line cereals not so good for things like sugar or anything that has a moisture content. don’t want to store anything probably like chocolate coffee would be a good thing to store in these kinds of bags and they’re good for up to forty years you don’t need to use mylar bags if you’re storing for under a year unless you’re really concerned about bugs or moisture or any kind of nutrient loss really that’s not gonna be an issue in under a year so if you guys wanted to know how to do it there you go you guys currently use mylar bags and have any tips or tricks i’m not an expert on this stuff, this is just what i do you guys out there I’m sure a lot of you guys are the experts on the stuff feel free to leave a comment below if you have any tips or tricks on this kind of thing and if you have any questions or comments leave those below as well if I will have the answer, I’m sure somebody else does if you like this kind of stuff like subscribe have a lot more videos coming out on prepping, on food storage on stretching your meat with different kinds of sauces and different kind ofrecipes a lot of different things coming out and we’ll look forward to seeing you on the next video Thanks for watching chickens want nothing to do inside their head

100 thoughts on “Using Mylar Bags for Food Storage”

  1. New to concepts of mylar bags kinda and curious about something. I live in a state where medical and recreational cannabis are legal. At dispenseries, when you purchase cannabis flower especially in the past year by the ounce they usually store them in mylar bags when sold. They are the smaller ones with a zipper and one side of the pouches are clear plastic. Would be reusable as well, do you think? I'm going to feel silly if I've been throwing out bags I could reuse this whole time. Seems like they wouldn't be since one side is plastic and clear. Thought I'd run it past you. Take care.

  2. You can store chocolate (chocolate chips/candy bars) etc. if you put it in a mason jar and use a vacuum seal (FoodSaver) attachment. I suggest checking out the Wendy Dewitt Food Storage seminar here on YouTube. It’s an older video but packed with some great info!!

  3. Packed a lot of wheat back in 99 but went overkill on sealing it. Used DE (diet earth), bay leaf (2 or 3), and set dry ice on a piece of paper towel inside the Mylar bag in the open bucket until it was almost gone. Trick is to MAKE SURE it is almost gone before sealing the mylar in the bucket. Make sure to remove the remaining dry AND THE paper towel before sealing. Then threw in the O2 absorber and sealed em in 5 gal buckets with new lids after sealing the bags, Needless to say I am still opening them to grind for the bread machine 20 years later and they are fine. Other urban myths were put in a piece of spearmint chewing gum to keep bugs down. Funny thing is we did it in a garage in the middle of the summer on a hot dry day. The dry ice chased out the air and O2 and then when we sealed them they went into the basement which was 20 degrees cooler. needless to say the whole batch of buckets sucked in a bit vacuum sealing them as they cooled.

    Last tip, we kept the dry ice in a cooler as we were using it so left the O2 absorbers in the bottom of the cooler while packing. Greatly extended the life of them as there was no O2 in the cooler due to the dry ice.

  4. Have seen a few videos on freeze drying. I suppose it would be ok to put freeze dried fruits, veggies, or even meats in mylar bags. Thoughts?

  5. Hi Jamie, I have many bags that just did not compress. LDS 7.5 Mylar. 300 cc absorbers. I cut those bags in half and used them (length wise.). I did get three that shrunk of the 12. So I started over with the ones that never shrunk the next day. Same thing nothing. So on the third time, ( I used new absorbers each time). I nothiced one mason jars with the absorbers had condensation in the jar. And none of th absorbers were getting warm. On yesterdays project and todays. Could I have gotten a pkg. of bad absorbers? I have watched many a video. I worked fast and methodical. Any suggestions.

  6. Here in Scotland people used to store their oatmeal i.e. dry coarse ground oats, not cooked porridge, in special grain chests called girnals. Just like you've shown in this video, people understood the meal had to be packed as tightly as possible to stop it from going bad. Parents would traditionally wash their children's feet and have them stand in the girnal barefoot, stamping the grain down as hard as they could so there was no air inside, almost like your mylar bags with oxygen absorbers. I should probably add that although they didn't store cooked porridge that way, people did pour it into a drawer lined with greaseproof paper and cut slices off to eat cold or fried like polenta. My great grandfather was a machinist working in shipbuilding and he took a slice of cold porridge wrapped in brown paper to eat at work every day.

  7. 2 questions:
    1. Why don't you vacuum them as well?
    2. Why do you (or anyone) store in 5 gallon bags? I feel this is an "all your eggs" option (bugs and molds etc) AND when you open it you will have to use X amount in a short time.

  8. Oh stink! I totally messed up. 🙈I just got mine in fedex from same company. I didn’t read chart and ordered 100 cc for one pound bags. I guess I will be using these for my hardtack on jars. What about once you take the beans and rice out of the freezer, how long do you dry them out after? Love your vids. Thanks for making them.

  9. Does anyone else have any trouble with the mylar bags ? I'm so frustrated with them. I put rice and beans in one gallon bags with 400cc absorbers about 10 bags. I go downstairs and decided to open the tote just to look at them guess what about half are not hard/sealed but they was when I put them in there. I don't understand. Please Help

  10. I was just curious I read twice it says that for the gallon bag that is 10 x 14 that you use 500 cc's it just says 1/4 rice wheat grains and flour and then you move over in for pasta and bean just says one 500 so I'm just curious for the gallon bag with a ziplock are you just being safe by using two or have you learned you should use to I'm confused

  11. How do the mylar bags with oxygen absorbers compare to vacuum sealed bags without oxygen absorbers? The air has been removed in the vacuum process, for the most part. We use vacuum bags and 5 gallon buckets to store them in.

  12. I would love to know how to storage other kind of foods, such as sauces, probably can foods. This video was very helpful. Thanks a lot!

  13. You can buy individually packed O2 absorbers in 500cc and 2000cc on Amazon and other suppliers. Great for slow pokes like me! Nice video, thanks.

  14. i see in your video on using mylar bags for long term storage you use oxygen absorbers. could you use carbon dioxide ( baking soda & vinager mix ) to displace a lot of the oxygen prior to using the oxygen absorbers & sealing the bags to insure all bugs & eggs are killed & insuring an even longer storage time ? thanks for all the vidios . keep up the great work .

  15. I Like the Quality Valuable Informative Video & I Really Like Her! She's Pretty Cool & Neat & is a True Knockout, WOW!

  16. Very interesting indeed! Whow Americans have it EASY living off grid. I have twice in my life with 2 children IN
    JAMAICA and On the Big Island of Hawai'i MUCH MUCH harder than this!!!!

  17. After bagged i washed cat litter containers {clean unused} in hot water and store food in those with oxygen eaters for the bucket.

  18. Jaime, this makes perfect sense. Thank you! I'm checking with the FoodSaver people to see if Mylar bags can be used with their vacuseal machines. Remove as much air and use oxygen absorbers for very best results, right? Thanks again!

  19. I would like to preserve tea, for drinking after shtf. They will be teabags and do my question is this, will Mylar be a good storage vessel for this use? How long will the dry teabags last?

  20. I love using the flat iron I actually saved up just buy a flat iron only for doing my mile are food saver storage although one thing that I really love about it is you can make a very wide seal if you so desire

  21. nothing chaps my hide more than going through all the work of dehydrating my figs only to open and find it infested with tiny worms

  22. can I use a straw to suck out the air before sealing the mylar. I get my buckets from the bakery dept at grocery store . They take a bit of work to clean but are good with a rubber seal

  23. I used to do Mylar for long term storage but stopped that all together. Mylar does transfer oxygen and moisture. So for short term I still use but have gone to a metal canner which is 100% effective against moisture and oxygen. Also those saying they will last 25 to 40 years have no data whatsoever to back that up. Most of that information comes from the packaging industry and those companies that use mylar in long term food. Also, when someone says they use Nitrogen in the bags, don't believe it. I have spoken to those who package for the industry and the word is production not application, so the production line is to fast to get good saturation in the can.

  24. I just found your videos. What I found when working alone. I use the straightener… but what I do is seal the whole bag completely except a corner to put the absorbers in it. Then I have it all sealed except the corners… I stuff the absorbers into the corner then I only have to seal up the one small corner vs the whole top of each of the bags. Just what I found what works for me.

  25. Hey guys, i need to seal small bags 3-4 inches by 6 to 8. Prefferably a heavy duty, or metalized bag. ideas or devices i need to look at please

  26. Hi and thanks for the informative video! When using the flat iron to seal bags, do you use the low or high setting? (New to those irons)

  27. So I did a small project and used a vacuum sealing machine for regular white rice and pinto beans I started both of them in a cool dry place and dark but before that I put them into the freezer for 3 days the rice is still going strong and it's been about six years but the beans turned a very dark brown color why and the other thing is I opened up a bag of rice and the bag of pinto beans and the pinto beans took an hour longer to cook the normal and they taste is not the same

  28. Hi GF, just rewind your video for that mystery bag, you have this one on tape! 😁 One question, is their a reason why you don't use Nitrogen? Please share with me as I want the best longevity. TY 💖

  29. Great video as always. Do you have a way of keeping up with your inventory in your pantry so that everything gets used and rotated?

  30. Hi, I am new to the whole prepping, one thing I noticed with the flat iron, why not seal most of the bag leaving a small opening and put a straw in and suck out the air and then seal it. Can you use mylar bags with a vacuum sealer?

  31. Love your videos! You've taught me so much, thank you!❤ I have a question, I used 4 1 gallon mylar bags with 2 300cc Oxygen absorbers each, 2 of them after sitting overnight are totally 'vacuumed' as in all the air sucked out, but the other 2 aren't like that. It doesn't seem that there is air in them but they are not sucked tight against the rice like the other 2. I hope that makes sense. Are they still ok?

  32. Can you leave food in their original packaging and still use the bags and do you have to use a iron for the ziplock bags?

  33. I am watching this for the second time and I just gotta say….. I never knew what that eye was for. Thanks for sharing.

  34. Where do folks source their bulk bags of beans – the largest I can find is a 20lb bag of Pinto Beans at Wally's World. Pintos are OK, but there are so many others I like.

  35. I immediately reseal the oxygen absorber pack after I take some absorbers out with the flat iron.

    That i believe works better than the mason jar.

    I also seal the mylar leaving 2 inches not sealed on one end. I place a small tip vacum cleaner in the slot to suck air out then quickly seal the 2 inch end. It works great!!

  36. why  don't you put the absorbers in a sealed container or tupperware with e lid, using one at the time and reseal the rest, also seal the mylar bug immediately, instead of having 30 bugs opened with the oxygen absorber waiting?

  37. Love your videos. My wife and I started prepping about 6 months ago. I always feel peaceful when I watch your videos and learn a lot in the process. Thank you for doing such great work!

  38. Your videos are indispensable. I've watched every tutorial video youve made, and when I have questions or need a refresher..I come watch them again. Thanks for sharing your knowledge, and helping us out here in YouTube land refine our techniques.

  39. I've found that when you have left over Oxy Absorbers that need to be stored for later use, after you've opened the original bag, as mentioned in this video, put them in a mason jar but if you have a "Food Saver" brand or any other vacuum sealer that can vacuum seal a mason jar, use that to suck the air out of the jar. This keeps the Absorbers from needing to work on the remaining air in the jar. I've found that it really prolongs the Oxy Absorbers that much longer. Just my 2 1/2 cents worth.

  40. I* like the way you do this. One thing you might think about adding is the same thing they do for grain storage in bins and silos. Put in a minor amount of Food Grade Diatomaceous earth. Get it at feed stores, it just has to be food grade, as anything else is not fine enough to work. It get in any bugs exoskeleton and dehydrates them when it damages the shells. It's also good for getting rid of bugs from farm animals and your house.

  41. Jamie or anybody, where can I buy bulk (50lbs) beans and rice? I’ve checked Sams Club and all they have here is 30lb bags of rice. No big bags of beans.

  42. I store basics like rice, beans, pasta in smaller packages. I use vacuum bags with a pound or max two pounds of product. Each bag gets a O2 with a desiccant pack. That's drawn down in a vacuum, then sealed in a mylar bag with O2 and desiccant pack. Those are packed into 5 gallon mylar bags with O2 and desiccant then sealed. Might be overkill, but I don't worry about my preps.

  43. Prefill your left over mason jar part way with loose rice. This will limit the O2 in the jar and make the left over O2 sachets better when you do come to use them . If there is not quite enough space for all the sachets, pour some rice out.

  44. Keep in mind – smaller bagged qty's can be carried in a bugout situation far easier than LARGE bags of food.

  45. Try sealing the bags most of the way and using a shopvac to remove the majority of the remaining air. This will help the content stay fresher over time.

  46. I have heard that people store rice in mylar bags when they are NOT using FOOD GRADE buckets. So, assuming the use of FOOD GRADE buckets, why not simply pour the rice into those buckets with oxygen absorbers? Could you also then add FOOD GRADE DE (diatomaceous earth) as an extra layer of protection against critters?

  47. There is an item called an impulse sealer that will work well they are a bit pricey but worth it they range from 4"-18" wide

  48. Just a tip in using the curling iron, seal the corners of the mylar bag on a diagonal and the center of the bag on horizontal by just clamping the iron on the mylar rather than moving it along the bag edge.

  49. You may have addressed this, but can you freeze these bags for those 3 days (to kill the bugs) AFTER you pack and seal them? Or does this HAVE to be done before they are packed and sealed?

  50. There are several reasons, but all are related: 1) because the curling iron is only about 5 inches long it doesn't reach all the way across the wider mouth opening, 2) with the sides crimped and melted diagonally the final crimping and melting will be in one smooth action, 3) the smaller opening allows more efficient physical evacuation (squeezing out) of the air inside before the addition of oxygen absorbent, 4) the smaller opening allows for a quick deposit and seal of the Mylar bag to more efficiently to begin the absorption quickly. Hope this helps!

  51. When storing sugar in mylar, should we put the whole original bag of sugar in the mylar bag? Or poor it out of the original bag before putting in mylar bag?

  52. I would put in some support braces in your shelves, you have 2×4 sag and its not gonna get any better. should've stood them up but still need support for that long a run. nice video
