TIPS ON SEALING MYLAR BAGS
for Long Term Food Stoarge

Mylar Bag Page

Using a Clothes Iron with a Teflon Coated botton.

Buckets:

Please read "More Info" on the oxygen absorbers before attempting this job.  Before placing your oxygen absorbers in the mylar bags on top of the food, manipulate the mylar bag so that it becomes flatened from the end down as close to the food as possible.  The best way to do this is once your food is in the bucket pick up on the end of the bag and lift it with bucket and food slightly off the floor only holding on to the bag and shake it up and down a couple of times to get the food to the bottom of the bag giving you more mylar at the top.  Then, pick the bucket up off the floor and slam it down on the floor a couple of times to get the food all the way down in the buckets bottom - do about two to three times.  Next, grab the mylar on both sides close to the bucket and pull both sides at the same time to get wrinkles out.  Make sure the portion above is also flat and relativley free of wrinkles.  Then fold the mylar to one side of the bucket (flat side of mylar) and push down on the top of the food to get the air out of the mylar, then fold the mylar back to the other side and push down again.  May need one or two more times then move the opening of the mylar directly up verically, then you will notice the mylar sitting almost flat on top of the food with a flat flap facing up (this minimizes air in bag before sealing).  Now push the flat flap down to one side to ready it for sealing.  Get all of your buckets ready this way.  Now, open your oxygen absorbers and place the adequate quantity in the mylar bag on top of the food making sure you limit the quantity of buckets you are sealing to a 10 to 20 minute job.  Now place your 30 inch "Full Round Wood Closet Rod" moulding (can be purchased at a hardware store or lumber yard - we do sell this as we are a lumber yard also) on the top of the bucket.  Now pull the mylar tight from left and right at the same time and lay it flat on the rod so there are no wrinkles at the rod.  With your teflon coated iron set at its highest heat setting, move it across the rod left and right till you have a sealed line (no wrinkles, none).  Then move the iron up some to make the seal a little wider moving the iron side to side.  Your done.  Now put the lid on!  Option:  You may want to attach the closet rod to a 1x4 pc of wood to lay on the bucket to prevent it from rolling off or moving while sealing the bag. It is advised to do a few test seals before you try sealing your food so remember to get a couple extra bags to do this.

Using the commercial heat sealers we sell is much faster and the quality can be acheived much easier.  The sealer will seal the whole bag within a few seconds and you don't have to worry about wrinkles like with the iron.  Get some freinds together and pitch in for one of these, its well worth it.

 

BUCKETS:  NOT USING MYLAR BAGS

Just place the adequate amount of oxygen absorbers on top of the food in the bucket and seal the lid.  If after a few days you notice one of the buckets not having a vacum or the lid is not pulled down a little, you should re-do this one and use a new lid.  Note that if you put your food all the way to the top the lid will not pull down much or at all under the vacum.

 

MYLAR BAGS ALONE

This job is best done with two people if you do not have a heat sealer.  Even with a sealer it is better for two people to do this to limit the exposure of the oxygen absorbers (O2's).  Have a 24" piece of wood closet rod at ready.   Fill the small bags up about 3/4 full or enough that you can place the bag over the rod and food not be to close to the rod to get into the seal.  The biggest thing is you do not want too many oxygen absorbers out waiting to be sealed up and waisting away.  See "More Info" on oxygen absorbers before attempting this job.  As with the bucket put your teflon coated iron to its hottest setting.  Pull the wrinkles out of the bag and lay it over the rod.  Make sure the rod is stabilized so it does not move when you are sealing the bag.  Then run the iron back and fourth till you have a sealed line.  Now, move the iron up slightly and move side to side agian making the seal wider.  You do not want any wrinkles in the bag at all.  Thats it.  Do not have oxygen absorbers exposed for more that 20 minutes.  It is better to limit them to 10 minutes.  You may attatch the rod to a 1x4 pc of wood to stabilize it while sealing.

 

Nitrogen

Nitrogen is cheaper than CO2.  The only difference is that weevils can live in low amounts of oxygen but are as active as the amount of oxygen that is left in the container.  Inject nitrogen along with using the O2's for a overdone job.  Inject the nitrogen right before you seal the bag for about 30 seconds.  Now seal the bag.  Remember the O2's are already in the bucket sucking oxygen so get the job done quickly.  Don't go over 20 minutes.
