PROPATECH VCI PAPER
Anti-corrosive paper coupled with polynet
Reinforced protection for heavy loads: anti-corrosive paper with net and film for sharp-edged and irregular manufactured goods.
The anti-corrosive paper PROPATECH VCI PAPER coupled with polynet represents the most robust solution for the protection of heavy metal manufactured goods with irregular shapes. This innovative composite material combines three fundamental elements: packaging paper impregnated with VCI molecules for anti-corrosive protection, reinforcement net for mechanical resistance and polyethylene film for waterproofing. This triple combination creates a complete protective system that unites anti-corrosive efficacy, structural robustness and barrier against atmospheric agents. Besides polyethylene, PROPATECH VCI paper can also be coupled with other materials such as aluminum, fabric or plastic nets. This way it is possible to create ad hoc materials for specific usage and protection needs, with different and complementary characteristics.
The main advantage of this product is the ability to handle difficult loads where traditional paper would be inadequate. The reinforcement net completely prevents tears caused by sharp edges, rough surfaces or mechanical stress during handling, while maintaining intact the VCI protective action. It is the ideal solution for directly wrapping large-sized pieces, lining containers of different materials (cardboard, wood, metal, plastic) and for all those applications where maximum resistance combined with total anti-corrosive protection is needed. The result is a safe packaging that offers product integrity and zero risks of damage during transport and storage.
Problems solved by this product
VCI anticorrosive products can be stored for up to a year and a half, but they must be kept sealed in the original package and not opened.
There are different types of VCI depending on metal to protect.
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.
Some anticorrosive VCI products, like paper and certain films, work well in contact with the material to be protected, whereas VCI diffusers, for example, do work at a distance in order to saturate the inside of packaging with the VCI substance and protect the goods against corrosion attacks. VCI products are very often used together to protect metals both in contact and at a distance and to better preserve their quality over time.
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.

Double-sided and poly-coated papers
VCI papers are the ideal solution for protecting and preventing rust on metals during shipping. The Turin-based company Propagroup offers two types of anticorrosive paper: Double-sided and poly-coated. The advantage of double-sided papers is that they have protective substances on both sides, and they are suitable to be used between two different layers of material. The poly-coated papers, instead, are manufactured by applying a layer of polyethylene, which prevents the loss of the protective substance. Lastly, Propagroup also offers pouches made of VCI paper, which allow fast packing for products with small dimensions.
Corrosion is a chemical reaction between a metal and its environment which results in a gradual destruction of metal and degradation of its properties.
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.
Ferrous metals contain iron, for example steel, whilst non-ferrous metals do not contain iron, for example zinc, magnesium, and copper.
It is not necessary, as PROPAGROUP VCI film and paper leave no residuals on goods. In fact, because of the absence of oil and grease, PROPATECH VCI is one of the client’s favourite products: they receive a qualitatively perfect, clean and ready to use product.
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 is the volatile distribution of VCI molecules into the packaging.
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.
A corrosion reaction in which the corroded metal forms an oxide; usually applied to reaction with a gas containing elemental oxygen, such as air.
Transformation from a solid to a gaseous state of VCI molecules starting from the protective material (paper, film, diffusers, foams, etc...).
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.
The Volatile Corrosion Inhibitor is a chemical substance that inhibits electrochemical oxidation of metals in reaction with an oxidant such as oxygen.
