Do these packets need a certain ratio of humidity in the air to begin oxidizing? Can they otherwise be used along with Silica in the same Mylar bag?

They start heating up the second they are exposed to air so you only have a short time to get them in place. Humidity does not have anything to do with their reaction only oxygen in the air.

As soon you open the package the oxy-sorb star warming , and has to use as soon as possible. And keep the unused one in an tight container. I didn't used silica with it, the oxy- absorb eliminates all the oxygen, and nothing humid could be inside the bag. This is my opinion.

No , between whats in the bag and the water in the syringe you shouldn't need to add any water. Just patience

This might work, you will need to do some calculations on how humid the air is, the temperature, and the volume of air in your car. I believe that Silica Gel can absorb 40% of their weight in moisture, so one 40 gram package could handle 16 grams of moisture. The weight of the water vapor at 80% humidity and 80 degrees is 125 grains per pound of air. The volume of air in the average car is 5 cubic meters, so the weight of the air would be about 13.12 lbs. This would mean there are 1640 grains of water vapor in the car, so the weight of the water vapor would equate to 106.3 grams. This means to adequately control ALL the water vapor in the car you would need 7 of these packs to control the moisture on a warm humid day. During cold winter months you could probably get away with just a couple. These calculations don't take into effect the humidity a human brings into the vehicle with exhaled breath.. etc. So it is possible to reduce the humidity with enough of these things, which would lessen the fogging of windows, but is it worth it? Maybe. A lot of factors were also not taken into account, so in practice I don't know how well it would perform. I use them for keeping my gym bag dry, and it works great for that.

I use mylar and find them extreemly durable and they work well with the heatsealer. Poly bags are more fragile and can melt too much on the heat sealer. They are cheeper. If you are not looking at long term storage or using for back packing or camping than poly may be OK for you. I just prefer Mylar. Bying it in large quantities saves money and gets the cost down a bit.

Yes, I have and some bags work fine and some bags require stopping the sealing process because the air has not been removed completely from the bag-----several times before you can let it complete the process !!!!! Very irritating!!!!

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.

Absolutely one time use. Once they have sucked the oxygen out of your Mylar bag or mason jar they have done their one time job and you just trash them after you open the container. If you want to reseal the same jar for another period of time just drop a fresh oxygen absorber in and put your same lid back on. Hope my answer has been helpful. Happy New Year!!

It's best to seal them in an airtight plastic bag. I also add silicon packs to the box. So far, everything has remained dry and it's been over a year.

They are not individually wrapped. You have to put any unused ones into an air tight bag or container right away to avoid having them use up their absorption capacity by taking up oxygen be just being exposed to the air.

What little bit of moisture there might be doesn't effect my insulin vials or syringes.

Answer here...You are keeping the lid closed ALL the time and there is no air circulation. I save the packages of gel silica from shoe boxes and vitamin bottles etc and toss them in -- it works fine, and I don't have a problem!

Mine came in two sealed bags with 30 in each bag for my pack of 60. You can either reseal this bag or transfer all of the pouches to another container like a mason jar. Just remember that each time they are exposed to oxygen they lose a tiny bit of their effectiveness. So try to work with them quickly and then hurry and reseal them. It would take a good while for them to be "ruined" though (at least an hour of exposure to open air).

No. Due to the smooth edges of the mylar it cannot form a vacuum. What I do is to put an oxidizer in the bag, use my jar sealer attached to a straw, seal the bag with a hot iron up to the straw, pull a vacuum as best you can, then quickly remove the straw and seal. The oxidizer in the bag will remove whatever air is left. You want to use extra oxidizers to ensure good air removal.

Yes! Make sure to seal air tight after opening the container. I love this brand.

Sorry Wendy. I do the same as the other respondent. The bags are huge and I always put them in airtight containers. I have a small bag from a local Amish bulk store and the ingredients on that label are the same as was previously mentioned in the other response.

I had some left over last year, and kept them in a thicker zip top bag... they were still fine (soft and squishy) this year when I got them out to use. I wouldn't add any moisture, as what was in there seemed sufficient. I was concerned about mold, but didn't seem to have an issue with it.

I keep them in the ziplock bag they came in just make sure that it stays sealed. It wouldn't hurt to throw onther bag over the first one, the big thing is to make sure they do not dry out
