PROPATECH VCI STRETCH
Anti-corrosive stretch film
A protective second skin: stretch film for integral wrapping and anti-corrosive protection of coils, bars and tubes
PROPATECH VCI STRETCH is a latest generation co-extruded stretch film that integrates the PROPATECH VCI additive directly into the molten plastic mass, creating a protective "second skin" that adheres perfectly to metal products. Thanks to its extraordinary elastic memory and high-quality resins, this film adapts integrally to the shape of products, offering total wrapping that prevents any oxidation process. It is particularly effective for steel coils, bars and tubes, even with extremely sharp edges, maintaining high mechanical resistance performance.
The PROPATECH VCI STRETCH system completely revolutionizes the traditional approach to metal protection, replacing old oiling and greasing systems with a more practical, economical and sustainable solution. It can be applied both manually and automatically, adapting perfectly to existing production processes without requiring modifications to packaging lines. The main advantage is the total elimination of pickling and post-opening washing operations: the products are immediately ready to use, clean and perfectly preserved. Being 100% recyclable and leaving no polluting residues, it represents the ideal choice for companies focused on environmental sustainability and operational efficiency.
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.

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.
Ferrous metals contain iron, for example steel, whilst non-ferrous metals do not contain iron, for example zinc, magnesium, and copper.
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 (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.
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.
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.
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.
It is very important to wear protective gloves as skin acidity can start oxidation of metal.
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.
