Description

Corrosion-inhibiting bag for firearm storage The present invention relates to a rust-proof bag for storing firearms. Corrosion prevention is essential for firearms to ensure stable long-term storage and maintain performance. Firearms made of metal are easily corroded by environmental factors such as moisture and oxygen in the air, which can lead not only to cosmetic damage but also to reduced accuracy and operational failures. Traditionally, oils or anti-corrosion sprays have been used to prevent metal corrosion, but these methods have the disadvantage of requiring reapplication and making cleaning cumbersome during use. Vapor-based anti-corrosion films are attracting attention as a technology to solve these problems. This film inhibits oxidation by forming a protective layer on the metal surface through the gaseous release of a rust inhibitor, without direct contact with the metal. By protecting the metal from moisture and oxygen in the external environment during long-term storage, vapor-based anti-corrosion films provide a convenient anti-corrosion solution that eliminates the need for reapplication or cleaning. Various developments utilizing these volatile anti-corrosion films are underway, and they are being used as a technology to effectively prevent metal corrosion in various industrial fields, including firearms storage. In particular, they are widely applied as a method to safely protect metals even in environments with severe climate changes. FIG. 1 shows a rust-proof bag for storing firearms according to one embodiment of the present invention. Figure 2 shows an aluminum-coated packaging material as a conventional packaging material for storing firearms. The present invention will be described in more detail below. However, the following specific examples or embodiments are merely references for the detailed explanation of the present invention and are not limited thereto, and the present invention may be implemented in various forms. Furthermore, unless otherwise defined, all technical and scientific terms have the same meaning as generally understood by one of the art to which the present invention pertains. The terms used in the description of the present invention are merely for the purpose of effectively describing specific embodiments and are not intended to limit the present invention. Additionally, the singular form used in the specification and the appended claims may be intended to include the plural form unless specifically indicated otherwise in the context. Furthermore, when it is stated that a part "includes" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Furthermore, unless otherwise specifically defined in the present invention, when a layer or member is described as being located “on” another layer or member, this includes not only cases where a layer or member is in contact with another layer or member, but also cases where another layer or member exists between two layers or two members. Additionally, terms used herein such as “about,” “substantially,” etc., are used to mean at or near the stated value when inherent manufacturing and material tolerances are presented in the said sense, and are used to prevent unscrupulous infringers from unfairly exploiting the disclosed content in which precise or absolute values are mentioned to aid in understanding the invention. The present invention will be described below. The present invention relates to a moisture-high barrier film; A volatile anti-corrosion resin film formed on one surface of the above moisture-high barrier film; as a rust-preventive bag for storing firearms laminated thereon, The above-described anti-rust bag for storing firearms has an insertion opening for inserting an item, and the item is inserted through the insertion opening and stored with the above-described vaporizable anti-rust film positioned on the inner surface, and after insertion, the insertion opening can be sealed in a zipper form or a knot seal form.
