VCI stretch wrap film is a specialized packaging material designed to protect metal products from corrosion (rust, oxidation) during storage and transportation. It combines the physical securing properties of standard stretch film with built-in corrosion protection technology.
What it is
VCI stretch wrap film is made from polyethylene (usually LLDPE) infused with VCI additives. These additives release corrosion-inhibiting vapors that form a protective molecular layer on metal surfaces.
How it works
- The film is wrapped around metal items or pallets
- VCI molecules slowly vaporize inside the sealed package
- These vapors settle on exposed metal surfaces
- A thin invisible layer forms, preventing moisture, oxygen, and contaminants from causing rust
Key Features
- Dual protection: Mechanical (wrapping) + chemical (corrosion inhibition)
- Transparent or tinted: Allows visibility of packaged goods
- Self-cling: Sticks to itself without adhesive
- Moisture and dust barrier
- Non-toxic and safe to handle (depends on grade)
- Easy removal: No cleaning required after unwrapping
Applications
- Steel coils, sheets, and bars
- Automotive components and spare parts
- Machinery and industrial equipment
- Bearings, tools, and metal assemblies
- Export packaging for long-distance shipping
Advantages
- Prevents rust without oils or greases
- Reduces packaging time and labor
- Keeps products clean and ready to use
- Cost-effective compared to traditional anti-corrosion methods
- Ideal for domestic and export shipments
Types Available
- Hand-grade VCI stretch film
- Machine-grade VCI stretch film
- Colored VCI films (blue/green for identification)
