How VCI
Works
A vapor corrosion inhibition
(VCI) technology which is a
patent and trademark of RustX
Moisture is reacted with VCI
Chemicals in vapor phase and
when it settles on Iron and is
neutral to oxidation

 Conventional Plant
 Single Layer Structure
Less Tacky film due to lower
impregnation of tacky
additives
Lower VCI Dosage
Lower Elongation due to
lesser take up

5 Yr. Corrosion Prevention- Better moisture
and oxygen barrier properties as a result of
advanced SMP VCI Technology
Reduced film usage
 Reduced Overwrap
 Thinner gauge films

17. Demonstrable Proprietary
technology provides higher strength
in low gauge films
Type of Polymers used distinguish a film
 Cross Linking increase functional strength
 A film made on a Co Ex plant is 30% stronger than
made on 1 layer plant or cast line
 Better polymers with lower MFI are used to
strengthen a film
VCI additive in the inner film maintain a ph of 8-9
inside the packaging
Tackiness on both outer and inner enable better
adhesion of the film layers
High elongation up to 900% results in lesser tearing
at the edges.

improvementimprovement
 High adhesive strength so the whole coil skin packed
and sealed and no moisture can enter packaging
 Corrosion prevention chemicals added to prevent
oxidation upto 5 years storage
 Excellent elongation and cocooning effect and the film
doesn’t tear from edges
 Special cross linked polymers put in the middle layer of
film for special strength on edges.
 600% - 900% elongation in the film

How Steel
oxidizes if
packaging is
not
appropriate

24.  Moisture during transportation –
100% RH with Temp of 45 - 48 C
 Breathing of the Packaging –
Changes in Temperature & Volume
of Air
 Removal Of Oil from the surface by
absorption
 Absorption of Humidity or water
retention by Interleaving Paper
 Rainfall during transportation
 Improper Storage Conditions
Causes ofCauses of
RustRust

25.  Snow causing seepage of water inside
the coils
 Poor tacky adhesives can lead to gaps
 Poor VCI is a major cause of non neutral
environment in packaging
 Rain Water, water at ports or sea can
seep through the edge of protectors
Only a good quality tacky
stretch can result in tightly
wrapped coil
