There are many ways of storing your belongings, and whether you’re getting ready for bugging in, bugging out, living off the grid, etc. you need to think about storage. Whether it is food, household items and whatever else you need for prepping. And how preppers store their food continues to evolve as we get better and better technology. Here we will talk about a kind of storage method which you might be familiar with, since so many preppers use it. It’s a simple piece of technology that we’ve come to embrace here at Prepper Base involving specially engineered gaskets on removable lids, commonly called a gamma lid. Also called “gamma seals” or a “gamma seal lid,” these lids spin on and their specially engineered gaskets ensure airtight protection.


In this post, we will cover everything you need to know about gamma seal lids and how they can come useful in a survival situation. We will also include a starter list showing you some of the foods that you can store with them for long-term storage.

What is a Gamma Seal Lid?

Gamma seal lids, also called as “gamma lids”, are lids which can transform ordinary 12” diameter buckets into reusable food storage containers. Once installed, they offer a leak-proof and airtight seal, which is clearly ideal for long term storage. And they have an easy open-and-close mechanism to avoid the trouble that some traditional snap-on lids have.


Furthermore, gamma seal lids are made of high durable, heavy-duty polyethylene plastic perfect for long term storage. And they usually fit 3.5, 5, and 7 gallon buckets with different size diameters, usually 12″ being the standard.


A quality gamma seal lid is going to be BPA-free high density polyethylene HDPE construction, have resilient elastomeric gaskets (usually made of stuff called styrene butadiene rubber copolymer), and will be able to fit on any perfectly good bucket. Don’t forget that you should have an easy opening lid, even though it turns a bucket into an airtight container. You’re still going to need easy access to whatever you have stored in your gamma seal bucket.


It’s easy and affordable to buy gamma seal containers, and they make a unique reusable plastic container. But one of the great things about using a gamma seal lid is that the heavy duty gasketed lid can be used with nearly any plastic bucket. All you need is a normal 3.5 to 7 gallon bucket and a lid that corresponds to the opening size. You can simply snap the adapter ring onto your bucket and use a rubber mallet to settle the gasket adapter ring onto the bucket. Once you’ve installed your ring, you have an air tight container whenever your removable lid is properly sealed.
