Anti-rust bag

Introduction to rust proof bags (gas-phase rust proof bags/VCI rust proof bags)

Core conclusion: Rust proof bag is a specialized packaging that integrates "physical protection+chemical rust prevention" functions. The core uses VCI (vapor phase rust inhibitor) to evaporate and form a rust proof atmosphere, or physically isolates water vapor/oxygen to prevent metal objects from oxidizing and rusting. The core value is "long-term rust prevention+convenient use+protection of metal appearance", suitable for storage and transportation packaging scenarios of various metal parts and equipment.

Basic definition and core characteristics

Rust proof bag is a functional packaging designed specifically for metal items, made of materials such as PE, PP, non-woven fabric, etc., with added rust proof ingredients (VCI rust inhibitor, desiccant, etc.), and achieved rust prevention through gas-phase action or physical isolation.

• Core components: substrate (PE/PP/composite film)+anti rust core (VCI vapor phase rust inhibitor/anti rust oil coating/desiccant)

• Core features: Long term rust prevention (3-24 months), moisture and water resistance, scratch resistance, partially anti-static/anti-corrosion, without damaging the metal surface

• Core difference: Different from ordinary PE bags, it adds active rust prevention function; Different from traditional rust prevention methods (applying rust proof oil), it does not require cleaning and can be assembled directly after use, improving efficiency

• Applicable objects: various metal materials such as steel, cast iron, copper, aluminum, galvanized parts, etc., covering precision parts, equipment, hardware tools, etc
