bags, how long do they keep o2 out, how long will they keep dehydrated foods fresh for? Dehydrated grains and fruit? How long does the seal last for?

When left in the fridge for over 6 months, sealed cheese is still fine -- not the freezer just the fridge. There's no evidence of any O2 or air entering the bag. 'Never tried to keep dehydrated grains or fruit, but if cheese in a fridge and meat or fish in a freezer keep for over 6 months without freezer burn, think how long dehydrated food would last...

I don't know scientifically the answer to any of these questions. I have only had mine for a couple months. Presumably as long as the seal integrity maintains and the O2 permeability of the bag is non-existent, it should last a long time.

I'm not familiar with how it works with dehydrated foods, but it holds a seal for the 30 days that we use it for in the fridge.

The seals are made by a heat bar and the bags are slightly melted and sealed together, I would think forever. The shelf life for dehydrated foods is greatly increased by vacuum packing. I don't know how long grains and fruit would last, it would probably depend on fat and/or water content.

it depends on the item freeze dry all most all 30 years or more. dehydrated 25 years or more . the can I have tried have all been pack the right way sealed with and oxygen removed. The LDS preparedness manual mite be off more help .

Most myler bag will protect seeds and survival type food 3-5 years that can be extended additional 1-2 years if kept in cool dark place or deepfreezer

I just got a bag from Amazon two weeks ago. Expires in Feb of 2016. I bought a storage container similar to a cereal container to keep food in and keep it fresh.

Hello, All Mylar bags must be heat-sealed to be effective. There are a few ways of doing this but I think the most common is to simply use a household iron. I have also heard of using a hair iron, which should work as long as it gets hot enough. The recommended sealing temperature is 400 degrees. They sell impulse sealers that work well but are not really worth it unless you plan on sealing a lot of bags. We usually recommend you rotate your food supply every year or two by actually using it. However, when properly sealed, low moisture food like you are storing can stay fresh indefinitely as it is protected from oxidation, bugs, light, mold, and oxygen dependent organisms. If you plan on extended storage, be sure to use quality American Mylar as small holes in the foil layer can let oxygen in whether the bag has been punctured or not, no matter how thick the entire laminate material is. A Long-Term Food Storage Guide is included with PackFresh products and you are always welcome to send us your questions as well. Have a great day!

These are wonderful almonds. I soak them for 48 hours in brine to release the enzyme inhibitors, then rinse and place in the dehydrator for 2 days. After that I place in an airtight glass container...the kind with the locking latch and rubber grommet. I eat the almonds in 4-5 weeks so I can't tell you how long they stay fresh. The dehydrating is key to helping them last longer tho...and you should really consider soaking them for even greater health benefits!

We have used this when doing chicken, and deer. We have sealed for several hours already and have had no issues I think we had it running for about 2 hours and still worked great the next time, you just need to be careful that there isn't much liquid in if you are just doing the bags. We love ours and have used it a lot and it works great.

I normally put the 2nd bag in the freezer. I've had some frozen for 6-12 months and it works just fine once I open it. What I have open is in an air tight jar and it keeps fine as well in the refrigerator for months.

They actually suggest refrigeration, but I order these in bulk in 25 lb boxes and store them in a large kitchen cabinet, and I can attest that they last at least a year. I would like to put some in my food storage but haven't tried it yet. I think if they're dry packed in foil pouches or buckets with an O2 pack, they would probably last quite a while. The big threat would be rancidity, but since they have a very low fat content, I think they'd be OK. I can't see why they'd be any different than TVP.

I keep mine in a large glass jar so I can seal it tightly and keep out moisture. I generally use the full bag within 3 months and have not had any problems, although in a humid zone you may need to worry about mold. My sister has let hers go over six months without issue, but for best usage I would perhaps freeze a portion if you aren't going to be using it regularly.

depending on the humidity of your region, they can stay fresh for a few hours to a few days. I found that placing them in plastic bags(gallon size) worked well to preserve them for over a week. I wouldn't suggest refrigerating them because it will add extra moisture, making them potentially soggy.

I buy 6 bags at a time and usually don't get to the last one until a year later. I have never had any problems! Once I open a bag I put them in a jar with a tight lid to keep them fresh. If you do that they should last quite a while and still stay relatively fresh :)

I believe the bag is air tight, but not airless. Also I've never noticed them go stale at all from being in the open air for months.

The package that the oxygen absorbers come in is airtight.Each packet is not.I use my food saver with a jar attachment to put all i did not use in a mason jar and remove the air this way each time you use them they are fresh.I also put a silica jell pack into the jar as extra protections.Before i did this i used a zip lock bag or a jar with lid ,the indicator changed in about 2 months whereas the vacuum packed jars i have almost a year and the indicator is unchanged.

T. Hanson, according to my research on-line, it depends on how and where you store the dried fruit. In pantry, cellar, etc. should last 6-12 months; refrigerator should last 1 to 2 years; freezer - indefinite. When I get these, I put 1 to 2 cups in my Food Saver machine (vacuum sealer) and seal them up, keeping them flat, then I stack them in a paper lunch bag - lying down on the counter - then, I stand the bags in my freezer. When I want them, I take out one "sealed" bag and let it come to room temperature, open it up and enjoy the best dried cherries and blueberries I have ever had. I have had some in the freezer for over a year now and used them during the holidays. You would have thought I had just received them. Traverse Bay is an exceptional product!! I hope this helps - if you have a more specific question, please post it!

This works just fine with dry foods. The sealing bar is inside the chamber. I have a different model which only works well as a vacuum sealer. It won't seal a bag without first drawing the vacuum since the vacuum is what causes the sealing bar to be pulled tightly against it's backing material.

The bag has a ziploc seal, but they stapled their cardboard sign to the bag so it has holes in it. I had to store them in another bag. The last bag I had lasted three years. Same as you 2 or 3 at a time. Even if they dry up, just put some water on them and they will still work .
