Understanding Different Types of Gun Storage Bags

PreservAll sells corrosion inhibitor bags. One of our most popular product lines – gun storage bags – are just that, corrosion inhibitorsBut like any other industry, there are many products available.

However, there’s crucially important information for those shopping for corrosion inhibitor products: Some corrosion inhibitors use ineffective & dangerous materials.

They can compromise the integrity of your guns through residue and will most likely lead to rust.

Understanding Different Gun Storage Bags


This Article Requires a Preface

There are certain designations of corrosion inhibitors that we’ll be unable to name throughout this article…this is for legal purposes. 

The objective of this article is to increase consumer awareness of potentially dangerous chemicals and materials in certain corrosion inhibitorsBecause we cannot explicitly state other brands of corrosion inhibitors in this article, we will hereby refer to corrosion inhibitors as either:

Intercept Corrosion Inhibitors vs Other Corrosion Inhibitors

  • Not all products in the Other Corrosion Inhibitors category are dangerous, but a great many of them are.
  • While we cannot directly name the brands contained in the category itself, we will say that members of the Other Corrosion Inhibitors group have a presence in the packaging marketplace.
  • If you’ve browsed for anti corrosion products before then you’ve come across them.

How Corrosion Inhibitors Work

A corrosion inhibitor has one primary purpose – to stop the degradation of whatever they’re aimed to protect.

Corrosion inhibitors can be used to protect a wide range of things, including firearms, tools, engines, electronics, heavy machinery, etc.

Products like these contain metals that corrode over time when exposed to certain reactive gases in the atmosphere. This results in increased costs, reduced efficiencies and additional labor for those involved.


Different Methods of Corrosion InhibitorsCorrosion Inhibitors Work in One of Three Ways:

NeutralizingAbsorbing or Blocking Reactive Gases.

 ✅ Neutralizing Reactive Gases ✅

Intercept Corrosion Inhibitors neutralize gases by acting as a preferential site of corrosion. The Intercept material bonds with the corrosive gases attempting to enter the bag.

This means that the Intercept Corrosion Inhibitors themselves corrode. Essentially, they “take one for the team”, leaving the item it has been stored with protected and unharmed.

Rather than the protected item corroding, the Intercept Corrosion Inhibitor itself degrades over time.

This is the technology employed in PreservAll’s gun storage bags and it’s the most efficient on the market.

 ❌ Absorbing Reactive Gases ❌

Some Other Corrosion Inhibitors will absorb reactive gases present in the atmosphere but fail to completely neutralize them.

These types of products simply retain the reactive gases until reaching their maximum saturation point.

Fluctuations in temperature and humidity cause them to outgas – this is the process by which a solid releases a gas that had been previously absorbed or trapped.

Other Corrosion Inhibitors absorb reactive gases without neutralizing them. This means that they re-release these contaminants.

They inadvertently expose the objects they were intended to protect with the agents of corrosion they were intended to eliminate.

Needless to say, these types of corrosion inhibitors are counterproductive.

❌ Blocking Reactive Gases ❌

There’s some Other Corrosion Inhibitors, that don’t absorb reactive gases at all.

Instead, they contain oils that vaporize into a chemical cloud/barrier layer inside their containers.

This barrier is designed to coat the item it’s supposed to protect. This hypothetically keeps reactive gases from causing corrosion on the item.

Inserted into coatings, adhesives, plastics, powders and sprays, these chemicals leave deposits on the items they’re designed to protect and are often inefficient.

These corrosion inhibitors never truly neutralize the reactive gases in the first place.

Rather than protecting the materials they’re intended to, Other Corrosion Inhibitors that utilize barrier layers can harm precious metals and serve as a potential health hazard.


Chemical Used in Barrier Layers

Someone looking for an anti corrosion product may come across a multitude of Other Corrosion Inhibitors and think they sound effective.

But what’s in these anti corrosion materials?

Nobody really knows.

This is because Other Corrosion Inhibitors rarely list the chemicals in their formulas.

Many don’t display their active ingredients and materials by way of listing them as “trade secrets”. In doing this, they aren’t obligated to disclose what they’re comprised of.

Research done by independent laboratories has exposed the active ingredients found in some Other Corrosion Inhibitors:

  • Truethanolamine
  • Ammonia Hydroxide
  • Ethyl Acetate
  • Trimethyl
  • Trimethylbenzene
  • Propylene Glycol
  • Butyl Acetate
  • Phosphoric Acid

Make no mistake, this is only a small sampling, and many other chemicals have been found as well.

Many of the chemicals found in Other Corrosion Inhibitors are on the EPA Registered Pesticide List, OSHA’s Air Contaminants List, and are found to be carcinogenic. Some are even flagged by the Chemical Weapons Convention.


Intercept Technology & PreservAll

Compare the previous list of ingredients with that of the Intercept Corrosion Inhibitors used in PreservAll’s gun storage bags.

  • Copper
  • Polyethylene

As you can see, there’s quite a difference. Intercept Corrosion Inhibitors are patented and since we don’t claim “trade secrets”, we have nothing to hide.

Our products contain a high surface area copper embedded into a polymer and nothing else. No volatiles, no carcinogens, no abrasives!

Intercept Corrosion Inhibitors have won environment awards, whereas many Other Corrosion Inhibitors have restrictions placed on them in other countries regarding health and environmental concerns.


These are important things to consider if you’re in the corrosion inhibitor market. Regardless of whether or not you purchase PreservAll bags or any other Intercept Corrosion Inhibitor products, we felt this was vital information that should be shared.
