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

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.

How long can VCI anticorrosive products be stored?

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. 

What VCI stands for?

VCI stands for Volatile Corrosion Inhibitor.

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.

Metal protection with VCI: which are the best solutions?

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.

Which are the advantages/disadvantages of plyethylene VCI compared to other VCI products?

VCI polyethylene has the big advantage of keeping VCI inside the packaging and of making a barrier, mainly isolating the product to protect. Furthermore polyethylene is very easy to use during packaging and the operations are much rapid, allowing an ease closing. As known, with the plastic packaging, in particular situations, is much easier that condensation occurs inside the packaging. This disadvantage can be easily solved with the use of desiccant products, perfect to reduce the humidity level, thus eliminating risks of damages caused by humidity. 

 

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 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.

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.

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.

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.
