Easy Pack Tape Company is a manufacturer of VCI Rust-Preventive Stretch Film for temporary corrosion protection of metal parts during warehouse storage, sea freight, transfer, and work-in-process handling. This VCI stretch film for metal protection combines vapor corrosion inhibitor technology with stretch wrapping performance, helping steel parts, machinery components, hardware tools, automotive parts, and metal pallet loads stay wrapped, stable, and better protected under clean, dry, and properly closed packaging conditions.
Product Overview
VCI rust preventive stretch film is made for metal products that need more than ordinary pallet wrapping. Regular stretch film can hold a pallet together, but it does not build a corrosion-inhibiting atmosphere around exposed steel, machined parts, tools, or metal assemblies. This film adds vapor corrosion inhibitor additives into a stretchable polyethylene film, so the wrapped space can support temporary corrosion protection while the film still gives cling, holding force, and pallet stability.
It is commonly used for carbon steel parts, cast iron components, galvanized steel, hardware tools, automotive parts, metal fittings, molds, machinery parts, and mixed metal assemblies. Thickness is normally selected from 15-80 um according to load weight, corner sharpness, and puncture risk. For hand wrapping, 50-500 mm widths and 150-1500 m roll lengths are common, while wider roll formats can reach 1000-4500 m.
Rust prevention depends on metal condition, film integrity, package tightness, overlap quality, and moisture control. Parts should be clean, cool, and visibly dry before wrapping. Cutting fluid residue, fingerprints, salt contamination, standing water, and condensation can reduce protection. For sharp-edged parts or heavy tool pallets, trial wrapping should check puncture points, edge closure, top and bottom coverage, cling, and load movement.
Benefits
– Combines corrosion inhibition and stretch wrapping in one film
– Helps protect steel, cast iron, galvanized steel, and selected non-ferrous metals
– Supports pallet stability while reducing rust risk during storage and shipment
– Suitable for palletized metal loads when individual VCI bags are not practical
– Can reduce direct oil coating when clean surface handling is required
– Custom VCI formulation can be adjusted for ferrous or multi-metal protection
– Trial wrapping can confirm puncture risk, overlap quality, and load stability
When is VCI stretch film a better choice for metal packaging?
VCI stretch film is a better choice when metal parts need short-term or medium-term rust prevention while still being wrapped as a stable pallet, bundle, or handling unit. It is useful for machined steel parts, hardware tools, automotive components, steel profiles, metal fittings, and machinery parts moving through warehouse storage, container loading, or sea freight. Unlike regular stretch wrap, this rust preventive stretch film is selected for corrosion inhibition first and load wrapping second.

How should metal parts be prepared before wrapping with VCI film?
Metal parts should be clean, cool, and visibly dry before wrapping. Cutting fluid, rinse water, fingerprints, salt residue, acidic contamination, or condensation can reduce the reliability of corrosion protection. Operators should also check for sharp edges, trapped moisture, open bottoms, and film puncture areas. A good wrap should cover the top, sides, and lower pallet area while keeping film tension within the 150%-300% working stretch range, so the load stays firm without tearing the film.
FAQ
Can VCI Rust-Preventive Stretch Film replace regular stretch film?
Yes, when metal parts need temporary corrosion protection during storage or shipment. If the load only needs carton holding or dust protection, regular stretch film may be enough.
Does VCI stretch film need direct contact with the metal?
Direct contact can help, but vapor corrosion inhibitor molecules can also protect exposed metal surfaces inside a properly wrapped space.
Which metal types can this film protect?
It can be made for ferrous metal packaging or multi-metal loads. Carbon steel, cast iron, galvanized steel, aluminum, copper, and brass should be confirmed before production.
What affects the rust prevention result most?
Main factors include metal cleanliness, surface dryness, VCI formulation, film thickness, overlap, edge closure, puncture control, humidity change, and shipment duration.
