Can Heat Shrink Film Prevent Rust and Seal at the Same Time?
2025-11-04 17:49Rust is a worry in the transportation and storage of metal products. The traditional anti-rust oil needs to be cleaned extra, and ordinary cling film is used. No matter how well the seal is, it can't stop the moisture. Can heat shrink film handle anti-rust and sealing at the same time?
Heat shrink film protection performance:
Heat shrink film can achieve anti-rust and sealing at the same time. In terms of rust prevention, the film contains vapor phase corrosion inhibitors, and these active ingredients will continue to be released slowly, forming a protective molecular layer on the metal surface. This kind of protection has good anti-rust function for ferrous metals, copper, aluminum and other metals.
In terms of sealing performance, when the heat shrink film shrinks by heat, it will tightly fit on the surface of the metal product to form a barrier. This barrier can not only effectively isolate moisture and pollutants in the air, but also increase the reliability of packaging with anti-aging and anti-static properties, and provide anti-rust packaging protection for various packaging items.
Widely applicable material compatibility:
Ordinary steel products to precision electronic components, copper accessories to aluminum parts, can obtain the same protection effect. And heat shrink film can be used for long-term anti-rust packaging of various metal equipment and large-scale equipment such as metallurgy, military industry, machinery, auto parts, electronics, hardware, etc.
When heat shrink film shrinks by heat, it can perfectly fit metal products of different shapes, workpieces with complex edges and corners or concave and convex surfaces, and can also be wrapped without dead ends. This tight fit not only enhances the sealing effect, but also ensures that the anti-rust components can function evenly.

Performance advantages of long-term protection:
Compared with traditional anti-rust packaging materials, the protection provided by heat shrink film is more durable and stable. The anti-rust components in the membrane can continue to evaporate, maintaining stable protection inside the package. In addition, the anti-aging properties of VCI shrink film wrap itself ensure that the material will not fail during long-term storage.
