Vacuum Sealing Mylar Bags for Long-Term Food Storage (The Easy Method) 

Like Jim, I too am a missionary in Ghana. I am also a sergeant in the fifth brigade of the interstellar survival group of the multi-species United Planets Coalition. Our last conference (which was held on the planet Nebulon 462) was focused on food preservation, so I can validate everything Jim Driscoll claims here.

​@@caesarleon1thank you for your service. 🫡🖖

Wow, you saved me! I saw this technique on a different video. The other day I packed up a couple dozen mylar bags of various things for the stock. I went to move it all downstairs today and they all lost their seal and had air in them. I rebagged it all and sealed down low, then cut the tail of the food saver off as much as I could then sealed again and boom! Solid vacuum and they're holding really well.

@@tannerortmann4187 glad I could help😊 Hope you have a wonderful day😁

I just watched this and don't understand why he put a piece of vacuum seal plastic in the top of the bag either. Following.

The piece of plastic has the channels for the air to be drawn from. The Mylar bag by itself won't allow the machine to vacuum the air out. It's clever.

@@woodbutcher951 Ahhh, that makes sense now. Thanks!

​@@woodbutcher951I'm new to all this myself. Your explanation helped but I still don't fully understand how the sealing happens. Is the vacuum sealer applying heat which seals the mylar closed too? Is it melted closed? With the little plastic section, how does it know when to stop vacuuming out air and then to seal it shut? Thanks in advance if you can help explain.

​@DonnaAndCats I have to confess. I've never personally done this method, but my friends and family have. Yes, it's "melted" together. (Sealed) His machine seemed to have attempted to pull more air out each time he added another seal. Whereas, most machines have a heat-seal-only button after the vacuum seal button was used. The machines have a limit switch inside it that measures when the vacuum is so high, the air is removed and it's time to heat seal. Hope that helps. I think it's clever, but I personally just use food saver bags in 5 gallon buckets. Mylar is significantly more durable though. Good stuff!

Try pressing the sealing button 2 or more times and it should seal.

I have done it similar. A large mylar bag it is filled with paper bags filled with rice , flour, sugar, seasoning, etc... wIth a couple of deoxygenators according to the size then sealed and placed in a bucket for reenforcement.

Mylar bags are made from a material called **biaxially-oriented polyethylene terephthalate (BoPET)**. This is a type of polyester film that is highly durable, flexible, and resistant to moisture, light, and oxygen, which makes it ideal for long-term storage. Typically, Mylar bags have a few layers: - **Outer Layer**: This is the BoPET film, which gives the bag its strength and durability. It's highly resistant to punctures and tearing. - **Middle Layer (often)**: Some Mylar bags include an aluminum or metallized layer to enhance their barrier properties, especially against light and air. - **Inner Layer**: The inner side of the bag is often made of a food-grade plastic (like polyethylene), which is heat-sealable and safe for storing food or other items. This combination of layers makes Mylar bags excellent for protecting against air, moisture, and light, which is why they are commonly used for long-term food storage, electronics, or pharmaceuticals.

I think the material use is worth it considering this food will be good for 20+ years stored this way.

@@breakaway.pastures like this you could propably store it for a thousand years. you'll get the exact same result with a simple glas jar though so my point stands.

We'll look into glass jars, thank you!

My vacuum sealer will not get hot enough to seal thick Mylar bags, what can I do

⁠@@RobinPridgen-bs3zy I saw another video that used a hot flat iron to seal it!
