| What
is corrosion (rust)? |
| • |
Corrosion is the
natural process of ferrous metal trying to return to its
original form of iron ore. |
| • |
Corrosion also
takes place in all metals in the same fashion (i.e., copper and
nickel corrosion is in the form of “tarnish”, aluminum corrosion
is in the form of white rust or aluminum oxide, etc.). |
| • |
Corrosion takes
place due to air (oxygen) and water (moisture) attacking the
surface of metal (known as oxidation) and creating the most
common form of corrosion, known as rust. |
| • |
Rust is a flaky
substance that appears on the metal surface, which was once part
of the metal, and is turned into iron oxide. This process is
also referred to as oxidation. |
What is VCI (volatile corrosion inhibitor)? |
| • |
KORINTM
VCI technology is a safe, dry, InterWrap patented chemical
technology that halts the natural oxidation process. |
| • |
VCI stands for
“volatile corrosion inhibitor”. This chemical process creates a
monomolecular barrier of KORINTM
material across the surface of the metal, by way of its own
chemical vapor emitted from the packaging material. KORINTM
is a harmless, dry chemical, which is chemically attracted to
the metal surface at the thickness of one molecule. This
protects the metal surface from the penetration of moisture and
oxygen stalling the natural corrosion process. |
| • |
Corrosion
protection is dependent on creating a 'closed environment'
around the metal so that the KORINTM
vapor will permeate throughout the packaged material. If the
package provides less coverage and is more 'open to the
environment', then the less the vapor (or KORINTM
protection) will permeate the
material and will simply go into the air, offering less
protection. If the package provides more coverage and is 'closed
to the environment', then the KORINTM
will stay within the package boundaries and protect the metal |
What are the estimated annual cost effects of corrosion in
today's environment? |
| • |
Corrosion is
estimated to cause more than $200 billion a year in total
product claims, returns and product failures. |
| • |
One single 'rust
claim' from a key customer can cost more than all the annual
dollars spent on packaging in total, in addition to significant
losses in goodwill and customer loyalty. |
How is VCI used in manufacturing steel wrapping materials? |
| • |
When producing
paper-based metals wrapping materials, VCI is formulated in a
liquid form and applied to the paper surface. When absorbed into
the paper, the VCI is emitted over time. |
| • |
When producing all
plastic metals wrapping materials, VCI is formulated in a pellet
form and mixed into the poly resin prior to extrusion. This
provides an even and specific concentration in the coated
surfaces, which are usually tinted to indicate VCI coatings.
