Foshan Opalus Adhesive Products Co., Ltd provides VCI Machine Stretch Film for Metal Corrosion Protection, designed for industrial metal packaging where load stability and corrosion risk control are both required. Made with an LLDPE-based stretch film structure and available in different thickness options, it is used for steel parts, automotive components, machinery assemblies, and other metal products requiring temporary protection during storage, shipment, and overseas transportation.
Why Ordinary Stretch Film Is Not Enough for Metal Export Packaging?
Standard stretch film mainly focuses on securing pallet loads and improving handling stability. For metal products shipped overseas or stored for extended periods, load fixation alone may not address corrosion risks caused by humidity, condensation, and transportation conditions. VCI Machine Stretch Film combines stretch wrapping performance with vapor corrosion inhibitor technology, helping create a protective environment around compatible metal surfaces inside the wrapped package.
Product Overview
VCI Machine Stretch Film is designed for automatic and semi-automatic wrapping operations where metal protection and stable pallet wrapping are both important. During packaging, the stretch layer helps maintain load stability, while VCI components gradually release inside the enclosed package environment and help reduce corrosion risks during storage and transportation.
VCI performance depends on metal type, surface condition, package design, and storage environment. Steel parts, cast iron components, aluminum products, copper parts, brass components, and mixed-metal assemblies may require different VCI selections. Before wrapping, metal surfaces should be clean and dry because moisture, machining residues, or contaminants inside the package may affect protection consistency.
For machine wrapping applications, roll width, roll length, core size, stretch ratio, and wrapping tension should match the intended equipment. Trial wrapping with representative loads can help verify film unwinding stability, pre-stretch settings, wrapping overlap, and final pallet condition before regular production.
Benefits
- Combines pallet stabilization with VCI corrosion protection capability for industrial metal packaging.
- Helps reduce corrosion risks during export transportation and warehouse storage when correctly selected and applied.
- Supports automatic and semi-automatic stretch wrapping systems with customized roll specifications.
- Provides reliable stretch, cling, and puncture resistance for industrial pallet wrapping requirements.
- Supports application evaluation through metal compatibility checks and packaging trials.
How Does VCI Machine Stretch Film Reduce Corrosion Risk During Metal Storage and Transportation?
VCI Machine Stretch Film works through a vapor-phase protection process rather than acting as a simple moisture barrier. Inside the wrapped package, VCI components gradually release into the surrounding air space and help create a protective environment around compatible metal surfaces. Corrosion performance should be evaluated according to metal type, package enclosure, humidity exposure, transportation duration, and storage conditions.
For critical applications, VCI testing, metal compatibility evaluation, and representative sample trials can provide additional confirmation before regular use.

What Should Be Checked Before Using VCI Machine Stretch Film on Industrial Metal Parts?
Before regular production use, actual packaging trials with representative metal parts can help confirm corrosion compatibility, wrapping stability, film tension, and equipment performance. For repeat orders, retaining approved samples, production specifications, and batch records can support consistent performance between different production runs.

FAQ
What makes VCI Machine Stretch Film different from standard stretch wrap?
Standard stretch film mainly secures loads, while VCI Machine Stretch Film adds vapor corrosion inhibitor protection for wrapped metal products.
Which metal types should be checked before selecting VCI film?
Steel, cast iron, aluminum, copper, brass, and mixed-metal assemblies should be reviewed because different metals may require different VCI formulations.
Can this film run on automatic stretch wrapping equipment?
Machine-grade versions are designed for automatic and semi-automatic stretch wrapping equipment, but roll specifications and settings should match the actual machine.
What factors affect corrosion protection performance during storage and shipment?
Metal condition, packaging method, humidity exposure, storage duration, and correct film selection all influence corrosion protection results.
