Active Protection: The Vapor‑Phase Corrosion Inhibition Principle of Anti‑Rust Films
Release Date:
May 13,2025
Source:
Rust‑preventive film is a functional packaging film for metal products that continuously releases rust‑inhibiting molecules within the package, forming a protective layer on the metal surface.
Working principle
The core technology of anti‑rust film is vapor‑phase corrosion inhibition. During production, a volatile rust inhibitor is incorporated into the film; once the package is sealed, the inhibitor gradually sublimates or evaporates, releasing anti‑rust gas molecules. These gas molecules diffuse to every corner of the metal surface—including crevices and pores—reaching areas that are difficult to fully cover with conventional packaging. They then adsorb onto the metal surface, forming a monolayer protective barrier that prevents corrosive agents such as moisture and oxygen from coming into direct contact with the metal.
Applicable Metal Range
Rust‑preventive films can be used for rust‑proof packaging of a wide range of metallic materials, including iron, steel, aluminum, copper, and galvanized components. However, it should be noted that different types of vapor‑phase rust‑preventive films may vary in their suitability for specific metals; some formulations may cause discoloration on certain metals. When selecting a film, it is advisable to verify compatibility based on the type of metal being packaged.
Protective Features
Compared with traditional oil‑based rust prevention, rust‑preventive film is a dry‑type method that eliminates the need to apply rust‑inhibiting oil during packaging. After removal, the parts can be used or further processed directly, without requiring any cleaning or degreasing steps. Moreover, the rust‑inhibiting gas can penetrate deep into internal cavities and blind holes of complex‑shaped components, providing comprehensive protection.
Rust‑preventive film is suitable for intermediate rust protection during the storage and transportation of metal parts, as well as for finished‑product packaging.
Other updates
Combining artificial intelligence with big data for corrosion simulation and analysis, providing customers with comprehensive solutions.
Located in Xiagezhuang Town, Laixi, the project has a total investment of RMB 50 million and is expected to begin production in September 2025, adding RMB 20 million to annual output value.
Active Protection: The Vapor‑Phase Corrosion Inhibition Principle of Anti‑Rust Films
Rust‑preventive film is a functional packaging film for metal products that continuously releases rust‑inhibiting molecules within the package, forming a protective layer on the metal surface.
The rust‑preventive performance of a rust inhibitor depends not only on the product itself but is also influenced by pre‑coating surface preparation, application method, and storage conditions.

In addition to using vapor-phase corrosion‑inhibiting products for internal protection, surface treatment of the pipe substrate itself represents another approach to achieving corrosion resistance.

During the storage and transportation of metal pipes and hollow components, internal wall corrosion is often an issue that is easily overlooked.
From Masterbatch to Film: Processing and Applications of Anti-Rust Masterbatches
Anti-rust masterbatches must be processed via blown-film extrusion to impart anti-rust functionality to plastic film products. From the addition ratio to the processing conditions, control during production directly affects the film’s anti-rust performance.
In the field of functional masterbatches, rust‑inhibiting masterbatches serve as a foundational raw material for producing vapor‑phase corrosion‑inhibiting films. By pre‑concentrating rust‑inhibiting functionality within plastic pellets, they offer a convenient solution for imparting anti‑corrosion properties to plastic products.
