PROPATECH VCI FILM
Co-extruded anticorrosive film
Transparent plastic film for total protection: 3-layer technology for prolonged preservation of metal products.
The PROPATECH VCI FILM co-extruded anticorrosive represents the most advanced technological evolution in metal protection from corrosion, manufactured through a 3-layer co-extrusion process that integrates the VCI additive directly into the molten plastic mass. Co-extrusion ensures greater mechanical resistance and mono-directionality of PROPATECH VCI molecules. This innovative technology uses a completely transparent film that allows immediate identification of packaged products, facilitating warehouse positioning, quality control and customs procedures without the need to open the packaging, thus reducing operational times and costs.
The triple functional layer system offers progressive and prolonged anticorrosive protection: the inner layer provides immediate protection, the intermediate one acts as a VCI reservoir for long-term protection, while the outer layer serves as a protective barrier that prevents the dispersion of anticorrosive molecules outwards, concentrating 100% effectiveness inside the packaging. This solution completely eliminates oxidation problems during transport and storage, is particularly appreciated by the global automotive and steel industry for its practicality and cost-effectiveness, and offers the possibility to choose versions with recycled plastics up to 30% or biodegradable for a more sustainable approach.
PROPATECH VCI FILMS comply with TRGS 615 standard.
Problems solved by this product
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.

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.
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.
Corrosion is a chemical reaction between a metal and its environment which results in a gradual destruction of metal and degradation of its properties.
There are different types of VCI depending on metal to protect.
Products for VCI (Volatile Corrosion Inhibitor) protection are used, during shipments and storage, to preserve and protect metals against corrosion. Propagroup has figured out and developed products for VCI protection, helping companies to preserve goods quality for a long time. The anticorrosive VCI products guarantee quality perseverance of shipped and stored materials, no claims for oxidation, considerable saving and big customer satisfaction. Propagroup created Propatech VCI system that, thanks to the reduction or even elimination of use of oil and greases, guarantees that the product remains intact, clean and ready-to-use. Propatech VCI doesn't leave traces and it is not dangerous, this is very important for protection, preservation, safety and saving. Propagroup is leader to solve problems of corrosion, humidity and impacts of goods during transport. Propatech VCI product range for metal protection includes the following products:
Papers, double face and polythene anticorrosion products, in addition to rolls, sheets and bags;
Films, anticorrosion plastic materials like Propatech VCI film, Propaskin, Propasteel, Propastretch and Propabol;
Emitters and diffusers of VCI substances like Propatech VCI Noxy, foams, tablets and anticorrosive pill bags.
VCI stands for Volatile Corrosion Inhibitor.
VCI (Volatile Corrosion Inhibitor) can be used for all products that need a corrosion protection inside the packaging such as steel coils, automotive spare parts, engines, complete machineries and all kind of metal parts.
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.
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.
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.
