Re-closable Long Term Storage / Preservation Bag (RCLTSP bag); for the prevention of corrosion on military and / or commercial weaponry

Abstract

This invention is a pre-made, re-closable, three-ply bag that has a clear serial number viewing window and is made from flexible packaging materials that collectively prevent corrosion from occurring on assets packaged within the bag while in transport or long-term storage. A VCI chemistry emitting film is used as the inner ply which surrounds the asset with corrosion preventive vapors. The center-play; provides ample cushioning and puncture resistance. The outer ply provides a strong puncture resistant vapor barrier which keeps corrosion causing elements from entering the bag and prevents corrosion inhibiting chemistry from escaping the bag. The use of a re-closable fastener enables asset packaging by un-skilled laborers as well as future asset inspection without compromising package integrity. Packing speed is forty times faster with this invention than previous methods. The invention also allows serial number verification without opening the package. Significant cost savings are achieved through its use.

1 . A re-closable bag that is fabricated from flexible packaging materials which provide long-term anti-corrosion protection to both ferrous and non-ferrous metal assets such as M16 rifles and/or other weapons, 
 allow convenient asset packing with no need of heat-sealing equipment due to the use of a hook & loop assembly, a zipper, mechanical snaps, pressure sensitive adhesive or a drawstring as the method of bag closure,    and provide a method of visual verification of the enclosed asset serial number without having to remove the asset from the bag, by viewing the number through the clear barrier window material heat-sealed into the side of the bag.    
   
   
       2 . The re-closable bag of  claim 1  provides superior puncture, tear and abrasion resistance over traditionally utilized MIL-PRF-131J flexible packaging materials due to the 3-ply construction of the bag wherein the outer ply is a flexible packaging material that provides barrier properties capable of minimizing the permeation of corrosion causing gaseous vapors and or contaminants in the environment through the material while at the same time preventing the escape of the corrosion inhibiting chemistry from within the interior of the bag, 
 while a center ply provides cushioning and additional puncture resistance and is made from polyethylene flat sheet netting, polyethylene or urethane foam, bubble pack, woven or non-woven flexible materials,    and an inner ply of linear low density polyethylene that is impregnated with Vapor Phase Corrosion Inhibitors such as VpCI®-126 Film from Cortec Corporation, or any equivalent film or material which prevents corrosion from occurring on any metal surface of any asset placed inside the bag while the bag is exposed to myriad environmental conditions.
