VCI STRETCH AND CLING FILM

WHAT IS CORROSION?

Corrosion is a constant, indiscriminate and costly enemy of metal parts, especially when packaged for storage and distribution. Traditional anti-corrosion methods are messy, costly and can be hazardous to personnel and the environment. Too often, they are ineffective as well.

Globally the losses every year due to corrosion are estimated to be unimaginable US$ 828 billion per annum. i.e. US$ 2.27 Billion per day. (NACE)

WHAT IS A VCI (Volatile Corrosion Inhibitor)?

VCI is a mixture of special chemicals that constantly vaporize and create gases, which have anti – corrosion properties. These vapors form a very thin protective film layer around the metal surface and prevent the metal from the corrosion action.

VCI chemicals dissociate into anions and cations with moisture as an electrolyte. These anions and cations associate with anodic and cathodic reactive areas respectively on the metal surface forming a mono-ionic protective layer, making it inert for any further reaction such as oxidation/rusting. Any loss of ions is replenished through further condensation of vapor ensuring continuous protection.

VCI Paper, or Vapour Corrosion Inhibitor paper, is a Kraft packaging paper manufactured with added VCI chemistry. VCI molecules protect metals from corrosion by forming a thin, invisible layer on the surface. This layer inhibits the corrosion process caused by oxygen, water and contaminants.

VCI Packaging can be offered in various configurations depending upon applications

VCI Stretch and Cling is a specially manufactured film designed to be anti-corrosive and provide cushioning strength to packed parts.

KEY FEATURES

o Protection of non-ferrous and composite metals
o Does not affect electrical optical and surface properties
o Eco-friendly and recyclable
o Designed for both automated and manual wrap film
o Can be stretched up to 300% of its length

CONSTRUCTION

VCI Stretch and Cling is a specially designed wrap film that protects metal parts from all types of corrosion, direct contact, and vapor action. The stretch and cling material is especially useful for protecting larger objects. VCI Stretch and Cling sheets can be specially designed as per customer requirements.

APPLICATION

The packaging of metal coils/sheets, pipes, tubes, automotive parts, engineering items, and electronic components
