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

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.

Does paper with volatile corrosion inhibitors exist?

Yes, it is possible to manufacture paper impregnated with VCI (Volatile Corrosion Inhibitors). VCI paper is a product that is very useful for solving the problem of corrosion during the transportation and storage of goods. Propagroup is specialized in the manufacture of VCI (Volatile Corrosion Inhibitor) paper, which is a crucially important product for eliminating harmful agents that can ruin metals. Propagroup handles the design, production, and marketing of systems for protecting products during transportation and storage; all of our solutions have been very successful, because they do not pollute, do not dirty, and are ready to use and very practical.

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.

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.

VCI can protect all metals?

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

 

Should a VCI be used in contact with a product or placed at a certain distance?

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.

Why is it important to wear protective gloves when working metals?

It is very important to wear protective gloves as skin acidity can start oxidation of metal. 

What VCI stands for?

VCI stands for Volatile Corrosion Inhibitor.

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.

How does VCI work?

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.

 

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.
