VCI-Treated Polythene Bags for Corrosion Protection of Metal Components During Storage and Export Shipment
Rust and corrosion are among the most costly and preventable problems in metal manufacturing, engineering and export. A component that leaves a factory in perfect condition can arrive at its destination corroded, unusable and commercially worthless — simply because the packaging was not engineered to protect it from the moisture, humidity, salt air and atmospheric contaminants it encountered along the way.
PolyCreations' anti-rust bags are manufactured from polythene treated with Vapour Corrosion Inhibitor technology — releasing odourless, invisible and non-toxic protective vapours that form an ultra-thin molecular barrier on every exposed metal surface inside the sealed package. The result is complete, active corrosion protection that requires no oils, greases, desiccants or additional coating — and leaves metal components clean, dry and ready for immediate use when the bag is opened.
Product Overview
At PolyCreations, we manufacture anti-rust bags from high-grade polythene treated with Vapour Corrosion Inhibitor technology — releasing odourless, invisible and non-toxic vapours that form a continuous molecular barrier on every exposed metal surface inside the sealed package. Unlike standard poly bags that only provide a physical barrier, our VCI-treated bags actively protect metal components from rust, tarnish and oxidation throughout the entire storage and shipment period. No oils, greases, desiccants or additional coatings are required — and when the bag is opened, metal components are immediately clean, dry and ready for use with no degreasing or residue removal needed.
Key Features
Active VCI Corrosion Protection
VCI molecules vaporise from the treated film and form a continuous invisible protective layer on every exposed metal surface inside the sealed bag — including recessed areas, holes and internal cavities that physical coatings cannot reach.
Non-Toxic, Odourless and Safe
The VCI treatment is completely non-toxic, odourless and harmless to operators, metal components and other materials in contact with the bag — containing no amines, phosphates, nitrites or nitrates.
No Oils, Greases or Desiccants Required
Eliminates the cost, mess and labour of applying and removing traditional rust-preventative coatings, oils and desiccants — components are protected from the moment they are sealed in the bag.
Immediate Use on Removal
When the bag is opened, VCI molecules dissipate rapidly from the metal surface — leaving components clean, dry and ready for immediate use, assembly, welding, painting or further processing with no cleaning step required.
High-Clarity Film
Manufactured from high-clarity polythene — components are visible through the bag without opening, enabling stock identification and quality inspection without breaking the protective seal.
Superior Moisture Resistance
The polythene film body provides a physical barrier against external moisture, humidity, salt air and atmospheric chemicals — working in combination with the VCI vapour to deliver dual-layer protection.
