PO VCI Bags
Our PO VCI Bags represent the absolute pinnacle of corrosion-inhibiting packaging technology, designed to protect ferrous and non-ferrous metals from rust during international ocean transport. We integrate premium Volatile Corrosion Inhibitor (VCI) molecular additives directly into our co-extruded polyolefin film. Once the metal component is sealed inside, our PO VCI Bags continuously release invisible, odorless VCI molecules that vaporize and condense on all metal surfaces-including hard-to-reach holes, slots, and threads-forming an active molecular protective layer that blocks moisture, salt, and oxygen from starting the oxidation process.
For industrial exporters, automotive manufacturers, and steel mill suppliers, rust during shipping is a massive financial risk. Using our corrosion-protection bags completely eliminates the need for messy, labor-intensive rust-preventative oils or greases. When the container arrives at its destination, your customers can simply open the bag and immediately put the clean, dry metal parts to work. This eliminates post-shipping chemical wash-downs, saving your clients significant labor and cleanup costs.

Flexible Commercial Payment Terms
We offer flexible payment terms to support long-term partnerships. Our standard term for custom production runs is a 50% deposit via T/T, with the remaining 50% balance paid prior to shipping. We support EXW, FOB, and DDP terms, accepting payments in both USD and CNY.
Manufacturing Scale & Capacity
Operating from a 6,000-square-meter facility with 40 skilled employees, we produce over 1,000 tons of high-performance packaging film every month. Our 15 modern film-blowing extruders are capable of running complex co-extrusion layers, allowing us to complete massive VCI orders within a reliable 15-day production cycle.
Engineering Customization
Our technical team can design bags to fit complex geometries, such as pre-formed 3D box liners, gusseted covers, and automatic packaging rolls. We support development directly from your technical engineering drawings, with physical custom samples ready within 15 days.
