A brief guide to corrosion-resistant packaging<\/h1>\n

In the processing and transport of metal components or sensitive equipment, corrosion-resistant packaging is essential. It protects metal parts from rust and damage, maintaining product integrity during storage and transport. In this guide, you will learn about each type of corrosion-protection packaging marketed by INATECH Packaging:<\/p>\n

What is corrosion and why does it occur?<\/h2>\n

Corrosion occurs when metal is simultaneously exposed to moisture and oxygen \u2014 this slow but continuous reaction can affect the structure of metals, compromising their functionality and service life. The costs associated with corrosion include material losses, refurbishment and energy consumption. Therefore, prevention is much more effective than repair. Suitable packaging is one of the most effective solutions for limiting these losses in the metallurgical, automotive or electronics industries.<\/p>\n

The role of corrosion-resistant packaging<\/h2>\n

Corrosion-protection packaging<\/a> creates a controlled environment around metal products, preventing direct contact with moisture and aggressive oxides. It acts as a physical or chemical barrier, inhibiting the oxidation process. These packages are particularly useful in situations such as maritime transport (where salty air is aggressive), long storage periods or exposure to unfavourable atmospheric conditions. They are used in the manufacture of metal parts and in the delivery of unassembled components.<\/p>\n

Types of corrosion-resistant packaging<\/h2>\n

Here are the main types of corrosion-resistant packaging available from INATECH Packaging:<\/p>\n

VCI packaging (volatile corrosion inhibitors)<\/h3>\n

VCI packaging (Volatile Corrosion Inhibitors) is made from paper or film impregnated with additives that vaporise and create a protective layer on the metal surface. This layer isolates the metal from aggressive molecules and moisture.<\/p>\n

VCI options include: VCI stretch film<\/a>, VCI kraft paper, VCI bubble film, VCI expanded polyethylene film, VCI bags<\/a>, VCI sacks and covers<\/a>. Aluminium foil shields with VCI additives also provide a high level of protection through an additional metal barrier.<\/p>\n

Barrier packaging (barrier film)<\/h3>\n

This packaging combines multilayer materials (metallised film + polymer) that provide a strong physical barrier against gases, moisture and oxides. It is used when long-term protection is required in aggressive conditions.<\/p>\n

Desiccants and vapour emitters<\/h3>\n

Desiccants, such as silica gel, absorb moisture from the packaging space, reducing the risk of corrosion. In addition, desiccant emitters or desiccant blankets can be placed inside the packaging for additional protection, especially in transit areas or in large packages. Common forms include silica gel sachets, desiccant blankets, desiccant hooks or standalone desiccant emitters.<\/p>\n

Advantages of corrosion-resistant packaging<\/h2>\n

Here are the main benefits of using corrosion-resistant packaging and rust-protection packaging<\/a> from INATECH Packaging:<\/p>\n

Durability and reduced losses<\/h3>\n

By protecting metals from corrosion, corrosion-resistant packaging reduces material losses and refurbishment or disposal costs. The metal component reaches its destination in optimal condition.<\/p>\n

Cost-effective and adaptable<\/h3>\n

Although sophisticated, VCI packaging has relatively low costs compared with the damage caused by oxidation. It can be adapted to the dimensions of the parts, while films and sacks can be customised.<\/p>\n

Safety and compatibility<\/h3>\n

This packaging is generally non-toxic, recyclable and does not endanger workers’ health. It leaves no aggressive residues and is compatible with most industrial environments.<\/p>\n

Long-term protection<\/h3>\n

Modern VCI packaging has an extended service life (often 5 years), providing long-term protection even during prolonged storage.<\/p>\n

Practical applications of corrosion-resistant packaging<\/h2>\n

Corrosion-resistant packaging is used in industries such as automotive, metallurgy, electronics and industrial equipment. It is indispensable for:<\/p>\n
