VCI stretch is a coextruded extendible film with the added VCI anti-corrosive system. The products of the VCI range are made by introducing the VCI additive into the still melted material during the film coextrusion phase. The additive is then able to sublime from the plastic, guaranteeing protection from the corrosion of the packed metallic details.
VCI stretch film is particularly suitable for the automatic or manual packaging of metallic items to protect from corrosion, especially steel reels, bars and tubes.
The high quality resins used for the production grant extremely high performances in terms of resistance, also for plates with extremely sharp edges. The elastic memory of VCI stretch film allows the product to be fully bound, granting it a "second skin" able to prevent any oxidation process.
Main advantages of VCI stretch film compared with VCI paper to pack steel coil
VCI stretch film can well work with automatic wrapping machines(produced by PESMEL or SIGNODE), packaging automation is available.
Low gram weigh, cost saving, 100% recycled.
Tightly close packaging, reliable packaging quality. Self-adhesive and packing function, no need to use tape or strip.
Excellent self-adhesive, wear resistant and anti-puncturing ability, effectively block water transmission.
Conformity to ROHS directive.
Effective corrosion protection and packaging combined into one step.
Provides safe and effective VCI protection for multi-metals during manufacture, storage and in transit.
Materials ready for use immediately out of the packaging.
Use VCI Film to wrap the metal. Similar to a film wrap.
Parts should be clean and free of fingerprint before wrapping.
Metal should be wrap closer to the film for better corrosion protection.
Let's take a closer look at how UV stabilized stretch wrap film or stretch film with a UVI (Ultraviolet Inhibitor) additive helps protect pallets from exposure to the sun.
Method of Providing Protection
VCIs emit small amounts of harmless active corrosion inhibitors. They are attracted to the charged surface of the metal. The flow of electrons in the metal and the flow of ions in the electrolyte surface are unable to operate and corrosion is halted. The length of protection depends on many factors and technology packaging staff are available to answer specific questions on corrosion protection or to provide detailed, objective proposals on suitable methods. This is true whether the problem relates to new projects or existing problematic transit and/or storage systems.
Handling & Storage Information
Ideally the material should be kept cool, dry and protected from direct sunlight. It is preferable to keep it in its original wrapping when possible. If kept in these conditions the material will be effective for a minimum of three years.
