A package for enclosing volatile corrosion inhibiting materials includes a first enclosure barrier being fabricated from one or more gas-impermeable materials and defining a first enclosed space. The package further includes a substrate having one or more volatile corrosion inhibitor materials disposed thereon, with the substrate being disposed within the first enclosed space. In some embodiments, a second enclosure barrier being fabricated from a gas-permeable, solid particle-impermeable material is disposed in the first enclosed space, and defines a second enclosed space inside of the first enclosed space. In such embodiments, the substrate is preferably disposed within the second enclosed space.

The invention provides a compound antirust packaging material and a manufacturing method thereof, belonging to the technical field of packaging materials. The compound antirust packaging material is formed by compounding three layers of structures, namely an inner layer of wood pulp spunlace non-woven fabric with functions of condensed water prevention and buffering, a middle hot melt adhesive layer providing gas phase antirust technology and having an adhering function, and an outer layer of high polymer thermal contraction thin film with functions of thermal contraction and aging prevention. When the compound antirust packaging material is manufactured, a thermal contraction thin film and a spunlace non-woven fabric are compounded together by solvent-free hot melt adhesive in an adhering manner. By utilizing the non-corrosiveness non-woven fabric as a base material, the compound antirust packaging material has functions of condensed water prevention and buffering; and by virtue of a thermal contraction process after a packaging process, a package material and a packaged object can be combined to form a whole effectively, and the outer thermal contraction layer and the middle hot melt adhesive layer can release a large amount of VCI (volatile corrosion inhibitor), and air pressure coated on the inner layer is increased at the same time, and thereby a better antirust effect is achieved.

A cleaning device for preserving a barrel of a firearm includes a central member defining a core and having a longitudinal length, a leading end and a trailing end. A tubular woven sheath surrounding the central member and has a lead end and a trailing end. A radial protrusion formed of a polymer is disposed about the central member between the central member and the sheath. A volatile corrosion inhibiter (VCI) is disposed on or in the cleaning device and configured to off-gas to cause a substantial part of an interior of the barrel to become lined with a protective coating to resist corrosion. The cleaning device is configured to be stored within the barrel of the firearm. A method for storing a cleaning device within a barrel of a firearm for preserving a barrel of a firearm is also described.
