ZCORR Products by Heritage Packaging

The Only Fail-Safe Corrosion Protection

HOW IT WORKS

How ZCORR Bags work:

ZCORR Bags™ utilize a combination of Vapor Phase Corrosion Inhibitor (VpCI) chemistry and barrier packaging materials to completely prevent the corrosion of your firearms and ammunition. The material that ZCORR Bags™ are manufactured with is a proprietary lamination of materials that conjointly yield anti-corrosion properties.

This laminated, anti-corrosion barrier material is puncture resistant, tear resistant, non-abrasive, non-toxic, and will not harm any non-metal surfaces. However, the most important features of the material are its VpCI impregnated sealant layer and its foil barrier layer.

The VpCI impregnated inner layer is where the anti-corrosive properties come from. The VpCI chemistry impregnated in the interior layer migrates out of the plastic and forms an invisible gas inside of the bag. This gas is made up of singular VpCI molecules that are attracted to the interior and exterior metal surfaces of your firearm. These molecules coat metal surfaces with a one molecule thick layer of VpCI chemistry that stops corrosion before it can begin. This one molecule thick layer of VpCI chemistry dissipates off of the firearm with no cleaning necessary when it is removed from the bag so that the firearm is ready for immediate use.

Foil barrier layers have been used in the packaging industry for decades and are recognized as the best material for blocking the transfer of gasses and water vapor through flexible materials. The foil layer in ZCORR Bags™ performs two tasks simultaneously; it keeps harmful corrosion causing elements out of the bag and keeps the corrosion inhibiting VpCI chemistry in the bag. This allows the bag to protect your firearms and ammunition for longer than any other product on the market.

The limiting factor on how long a ZCORR Bag™ will provide anti-corrosion protection is how long the bag is able to keep the VpCI chemistry locked in. Because the foil barrier layer does not let any VpCI chemistry permeate it, the only way for it to escape is when the bag is opened and closed. Bags that are repeatedly opened and closed will maintain their protective qualities for approximately 5 years. Bags that are not opened frequently can maintain their protective qualities for up to 20 years.

How VCI Chemistry works:

Corrosion begins when an electrolyte (water, oxygen, or humidity) is present on the surface of a metal. When this happens, electrons then flow from high-energy areas of the metal to low energy areas in a loop, through the electrolyte. The corrosion process results in the formation of oxidation on the metal surface. VCI molecules stop this reaction by passivating the surface and inhibiting or depressing the electro-chemical mechanism that triggers oxidation, i.e. the current flow from anode to cathode. Electrical current attempts to flow from the anode through the electrolyte into the cathode but cannot, because of the VCI’s presence. VCI molecules attach themselves to a metal surface to form an invisible monomolecular layer to protect metal from attack.

FREQUENTLY ASKED QUESTIONS

Do I still have to clean my gun if I use a ZCORR™ bag?
Yes, ZCORR™ Firearm Storage & Preservation bags work best when used with a well-cleaned firearm. Firearms should always be cleaned after firing and before being placed inside a ZCORR™bag for storage. However, cleaning isn’t necessary during storage, unless the firearm is removed from the ZCORR™ bag and fired or mishandled.
Will the wood and plastic parts on my firearm be safe inside a ZCORR™ bag?
Yes, the VpCI molecules are only attracted to metals, and are completely harmless to all other surfaces.
Will ZCORR™ bags tear or rip during normal use?
No, all ZCORR™ bags are made from a durable, puncture and tear resistant material. If handled properly, and used only as a storage device, the bags will perform perfectly. However, ZCORR™ does not guarantee against improper use of the product. ZCORR™ bags are not meant for transporting or carrying firearms. The bags can rip or tear when being used for purposes other than storage.
Do ZCORR™ bags really prevent firearm rust and corrosion for 20 years?
ZCORR™ bags work by emitting VpCI molecules that instantly cling to any metal surface placed inside the bag. This creates a buffer between harmful, corrosion causing elements and the metal of your firearm. This buffer blocks rust and corrosion from forming, keeping your firearm as spotless as the day it was first stored. As per the laws of physics, some of the molecules escape from the bag every time it is opened. For firearms that are removed from the bag often, a minimum of five years of rust and corrosion protection can be achieved. Firearms that are rarely or never removed from their ZCORR™ bags will retain more VpCI molecules inside the bag and last much longer.
H these bags really work? Who tested them?
The M16-A2 Long Term Storage & Preservation Bag (the military precursor to ZCORR™ bags, developed for the U.S. Marine Corps) was thoroughly tested by the United States Army Materiel Command Logistics Support Activity Packaging Storage and Containerization Center (USAMC LOGSA PSCC) in Tobyhanna, PA. The M16-A2 Long Term Storage & Preservation Bag met or exceeded all tests performed by the facility and was proven to provide firearms with long-term protection from rust and corrosion. The USAMC LOGSA PSCC serves as a proving ground for all industry-developed design concepts in the areas of storage and containerization.
How do these bags compare with offerings from competitors with VpCI bags of their own?
ZCORR™ bags are the only firearm storage and preservation bags whose technology was tested and approved by the U.S. military. ZCORR™ bags are also the only product to offer a foil barrier layer, VpCI protection and a military tested Velcro™ closure in one affordable package. The U.S. Marine Corps only chooses the best when it comes to storing their M16-A2 rifle. Now, everyday firearm owners can do the same with ZCORR™ bags.
These high-performance bags far exceed anything offered by competitors in the areas of strength, design and longevity. Other bags don’t utilize effective barriers, allowing the corrosion-preventing VpCI molecules to escape. Some competitors even make their customers purchase an outer bag and the VpCI emitter separately. These emitters last less than four months forcing the customer to repeatedly purchase more and more of them to protect their firearm. The ZCORR™ bag’s VpCI molecules arrive embedded inside an air-tight bag, which is ready to begin protecting your firearm from rust and corrosion immediately in an all-in-one package.
