Mylar Bags, Bucket Stacker

Click here to view the original post.

I found something new (to me anyway) in Mylar Bags used for Long Term Food Storage. It’s called “Bucket Stacker Bags”. They are premade in the shape of a stop sign, which when filled with one gallon of food allows five neatly stacked on top of one another inside a 5 gallon bucket. When you need to access some food you simply take the lid off the bucket, take one bag out and replace the bucket lid.
The advantage to using these bags over one large 5 gallon bag is you will not have to open then reseal the large bag which can be problematic because of all the wrinkles along the new reseal opening. The wrinkles are caused by stuffing the large Mylar bag into the bucket the resulting wrinkles may not allow a 100% seal and thereby possibly compromise the remaining food in the five gallon bag.

I now use the Bucket Stacker Bag exclusively because it’s smart and it works.

I did a similar thing but using regular rectangle gallon bags:

Manufacturers Product Description:

Bucket Stack Mylar bags

“These are super tough, 6 mil, food grade Mylar foil bags and are shaped so that when filled they stack in layers into a 5 or 6 gallon bucket.

What are the advantages of using these? Well here are a few!

#1: You don’t have to open a huge 5 gallon size bag of one product and risk it going bad or getting bugs before you use all of it. Even if you wish to put up 50 lbs. of one item like rice for example, you are still much better off having 5, 1 gallon individually sealed bags in the bucket than you are to have one huge 5 gallon bag.

#2: The seal on a Mylar bag is an easy place for the integrity of the bag to be compromised. When you heat seal the top of a 20” bag, that is a long seal and you must have a smooth, wrinkle free seal the entire width of the bag. With these bucket bags however, all you have to seal is the end of a 5” wide opening. No more fighting with the sealing iron trying to keep everything lined up and smooth and then worrying about if it is good enough or not.

To use these just fill the bag from the open end “spout”, (You may find it helpful to use a large funnel to fill the bag) drop in an oxygen absorber, then heat seal the opening shut. Now layer the bags inside of your buckets until the bucket is full and put a lid on it.

Note: These do have a zipper on the open end however we recommend not using it and actually heat sealing just below the zipper.”

Where to Purchase Link:

Here’s a new Stacker Bag. My camera lens distorted the stop sign shape, it’s really quite symmetrical and is a shiny silver like a normal Mylar bag. The filling snout is about 5 inches across so a funnel is needed to fill the bag with.

Using a funnel to fill the bag. I taped the funnel to the bag while filling otherwise the funnel just slips off. Having a helper hold the bag and funnel would be the way to go.

Four bags filled and ready to be sealed.

The bag filled and sealed. The photo makes the bag look blown up but it really is quite flat. The date is when the original date wheat grain was purchased and bagged.

After removing the O2 absorbers needed from their bag, I resealed it.

A close up of the seal. Per the manufacturer’s instructions, my seal is just below their built-in zip-lock feature.

The four bags resting for about 10-15 minutes so the O2 absorber could start consuming some of the O2 in the bags. This makes it easy to stack in the bucket, and not trying to stack what feels like balloons.

Caution; do not wait too long or the absorbers will eat enough air to create a very strong vacuum and in that case, turn the wheat grain into a ridged house brick unable to conform to the round bucket.

Here are four Stacker Bags of wheat grain in the bucket. As you can see there is room for one more bag giving a total of five gallons. The reason I didn’t bag the fifth gallon is because I needed some grain and had to open a five gallon bag to get a gallon of grain for myself. So, I only had enough to fill four bags.


I like them, good quality and fits my long term food storage method. The cost is $0.75 each, about $0.20 more than the typical rectangle bag.
