PROPASTEEL VCI
High-strength anticorrosive plastic film

The thin strength for heavy industry: ultra-resistant film for pipes, coils and machinery with sharp edges

PROPASTEEL VCI is a new generation coextruded plastic film, made with special technological resins that provide exceptional puncture resistance and cutting resistance capabilities. This innovative product has been specifically developed for the metallurgical and steel industry, where traditional plastic films cannot withstand the mechanical stress caused by pipes, coils, machinery with sharp or protruding parts. When treated with the PROPATECH VCI system, it combines the mechanical protection of packaging with excellent anticorrosive protection, creating a complete solution for the preservation of metal products.

The innovative characteristics of PROPASTEEL revolutionize the approach to industrial packaging: it is 100% recyclable unlike traditional laminated products, easily weldable to offer hermetic seals and highly economical thanks to high yield per kilogram. Despite its contained thickness, it provides superior resistance that makes it particularly competitive in terms of cost per square meter. It definitively solves the problems of breakage during handling of heavy loads and angular items, can be used both manually and automatically, and offers low permeability for prolonged protection.

The PROPASTEEL PLUS version represents the most advanced evolution with superior mechanical performance, very low permeability and greater anticorrosive protection.

PROPASTEEL is normally supplied in rolls but upon request sheets, bags, bellows covers or other formats can be produced. PROPASTEEL can be customized both graphically and in terms of coloring (standard color blue).

Problems solved by this product

VCI can protect all metals?

There are different types of VCI depending on metal to protect.

 

Is VCI dangerous for the health of people working directly with anticorrosive products for packaging?

Anticorrosive VCI products used in the packaging are not dangerous for the health of people because VCI is a physiologically inactive substance. Any problem of eye or skin irritation have been found in people that directly worked with packagings treated with VCI. In any case, because VCI is a chimical substance, is suggested the use of gloves when in contact with the anticorrosive packaging. We also suggest to always ask for the safety data sheet to our customer care before using anticorrosive Propatech VCI products for your packagings.

What VCI stands for?

VCI stands for Volatile Corrosion Inhibitor.

Which anticorrosion packing should be used to achieve VCI protection of metals?

Anticorrosion protection

To ensure proper protection of metal goods during the transportation phases, it is necessary for the packing to be made with suitable anticorrosion products. Propagroup is the leader in designing and developing antioxidant treatments able to effectively resolve the various problems of companies that transport and store metal goods, offering valid and safe anti-rust treatments in the Italian and international markets.


Antioxidant films, paper, and bags

Propagroup has launched on the market VCI anticorrosion packing items to guarantee adequate protection of metals. The most-used products are: paper; shrink films; bags; and covers for protecting metal automotive components such as engine blocks, transmissions, gearboxes, and brake discs, as well as steel coils, entire machines, and metal products in general.


Completely recyclable items

Continuous investments in research and development combined with the expertise and professionalism acquired over more than 40 years in the market have allowed us to expand our market not only in Italy and Europe, but all over the world. The packing we offer is ideal for solving any problem regarding corrosion, humidity, or condensate, and also includes many anti-impact products. We operate in full respect of the environment, and we develop completely recyclable products that are entirely compliant with all environmental laws, regulations, and standards applicable to companies.

Do VCI products have an active side?

There are 2 types of VCI paper: double-faced paper, impregnated on both sides, or one-sided PE coated paper. This latter is active only on one side, while the other consists of a barrier film able to keep the VCI within the package.
VCI film is always active on one-side.
On both VCI paper and film the active side (to be oriented toward the metal) is easily distinguishable, as it is opposite to the printed side.

What are ferrous and non-ferrous metals?

Ferrous metals contain iron, for example steel, whilst non-ferrous metals do not contain iron, for example zinc, magnesium, and copper.

What is the role of desiccants in protecting against oxidation?

Desiccant bags absorb humidity in the package, hence they reduce risk of oxidation. Still, to protect a material against corrosion, it is necessary to use a Propagroup VCI product as well.

What happens to VCI after the packaging received is opened?

VCI is a volatile substance so, once the packaging is opened, it volatilize from metal in one or two hours and it will not leave resuduals.

Should desiccants be used together with anticorrosion products?

We recommend using desiccants inside your package, even in those made of VCI films, in order to improve corrosion protection.

Lab tests together with our over 40 years of experience confirm that the combination of VCI Propatech products with Propasec desiccant bags increases the effectiveness of both of them extending the protection of your goods.

What is corrosion?

Corrosion is a chemical reaction between a metal and its environment which results in a gradual destruction of metal and degradation of its properties.

Corrosion

The chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties.

Diffusion

Diffusion is the volatile distribution of VCI molecules into the packaging.

Nitrites

PROPATECH VCI products for the protection against corrosion are free from nitrites.

Nitrites are made of a nitrogen atom and two oxygen atoms negatively charged and it can be found in some anticorrosive VCI products on the market. Its presence has to be allowed and declared from the producer.

Oxidation

A corrosion reaction in which the corroded metal forms an oxide; usually applied to reaction with a gas containing elemental oxygen, such as air.

Rust

Rust is a general term for a series of iron oxides. Colloquially, the term is applied to red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture. Rust generates metal corrosion.

Sublimation

Transformation from a solid to a gaseous state of VCI molecules starting from the protective material (paper, film, diffusers, foams, etc...).

VCI

VCI is a Volatil Corrosion Inhibitor that can sublimate, from a solid to a gas state, and form a thin invisible layer able to neutralize corrosive agents such as: water vapour, oxygen, saline atmosphere, sulphurous gases and the most common industrial environmental pollutants present in the air.

Volatile Corrosion Inhibitor

The Volatile Corrosion Inhibitor is a chemical substance that inhibits electrochemical oxidation of metals in reaction with an oxidant such as oxygen.
