PROPATECH VCI PAPER
Polyethylene-laminated anticorrosive paper
Enhanced anticorrosive protection: waterproof barrier that concentrates VCI action inside the packaging.
The polyethylene-laminated PROPATECH VCI PAPER is an advanced anticorrosive paper made by applying a polyethylene layer to the base paper impregnated with VCI molecules. This innovative combination creates a dual protective function: the polyethylene acts as a waterproof barrier against external atmospheric agents (humidity, rain, condensation) and simultaneously concentrates the emission of anticorrosive substances exclusively inside the packaging, preventing any external dispersion and maximizing protective effectiveness.
The main advantage of this technology is the optimization of anticorrosive action thanks to the drastic reduction of dispersions. The polyethylene-laminated paper solves deterioration problems caused by external humidity and provides prolonged protection even in severe environmental conditions. It is particularly suitable for long-term shipments, storage in humid environments and for all cases where total protection from corrosion and atmospheric agents is necessary. The result is perfect metal preservation with maximum product economy and zero waste of active ingredient.
The PROPATECH VCI PAPER papers comply with TRGS 615 standard and are recyclable.
Problems solved by this product
Ferrous metals contain iron, for example steel, whilst non-ferrous metals do not contain iron, for example zinc, magnesium, and copper.
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.
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.
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.
VCI is a complex combination of substances which sublimate and form a thin invisible layer able to neutralise corrosive agents, such as water vapour, oxygen, salty air, sulfur-based gases, and polluting agents commonly present in the air.
It is very important to wear protective gloves as skin acidity can start oxidation of metal.
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.
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.

Corrosion is a chemical reaction between a metal and its environment which results in a gradual destruction of metal and degradation of its properties.
The quantity of VCI to be used in order to effectively protect goods against corrosion depends on many factors, being the most relevant: shipping time, external conditions (e.g. by sea, by land), and type of product. We strongly recommend to contact us in order to determine the most efficient solution and design the most appropriate package.
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.
