Corrosion Protection Built into the Package

Metal parts can be exposed to humidity, condensation, salts, contaminants, and temperature changes during production, storage, handling, and transportation. Traditional packaging paper may provide separation or cushioning but does not actively protect metal against corrosion.

Cortec® VpCI® papers release Vapor phase Corrosion Inhibitors within an enclosed package. These inhibitors diffuse throughout the package and form a protective molecular layer on accessible metal surfaces. Depending on the product, the paper may also provide direct-contact protection, moisture resistance, grease resistance, cushioning, reinforcement, or static-dissipative properties.

Types of Cortec® Paper Products

Multi-Metal VpCI® Kraft Paper

Multi-metal VpCI® kraft paper protects a variety of ferrous and non-ferrous metals within an enclosed package. It can be used for wrapping, interleaving, separating, or lining containers without applying oil or grease directly to the metal.

Moisture-Barrier Paper

Moisture-barrier paper combines corrosion-inhibiting technology with resistance to water vapor, grease, or oil. It is useful when packaged metal may encounter fluctuating humidity, condensation, or demanding transportation conditions.

Reinforced Paper

Reinforced corrosion-inhibiting paper provides additional strength and resistance to tearing or punctures. It is suitable for wrapping large, heavy, irregular, or sharp-edged metal components.

Polycoated Barrier Paper

Polycoated paper combines Cortec® VpCI® protection with a polymer barrier layer. This format may be selected when additional moisture resistance, grease resistance, or package durability is required.

Creped Paper

Creped paper provides flexibility, conformability, and cushioning for wrapping irregular shapes or separating parts that may move during handling and transportation.

Static-Dissipative Paper

Static-dissipative paper combines corrosion protection with control of electrostatic buildup. It is designed for packaging sensitive electrical, electronic, and metal components that may require both corrosion and static protection.

Specialty Corrosion-Control Paper

Specialty papers are available for applications involving corrosive gases, sulfur-sensitive materials, moisture barriers, special metal combinations, or other challenging storage and shipping environments.

• Stainless steel
• Galvanized steel
• Aluminum
• Copper
• Brass
• Zinc
• Selected alloys and multi-metal assemblies

The metals and surface finishes in the package should be identified before selecting a paper. Specialty applications involving precious metals, sensitive electronics, painted surfaces, or unusual alloys may require compatibility testing.

Choosing the Right Paper Format

The appropriate paper depends on the part, packaging method, handling environment, and required protection period.

• Standard kraft paper: For general wrapping, interleaving, and multi-metal corrosion protection.
• Barrier paper: For packages requiring additional resistance to moisture, oil, or grease.
• Reinforced paper: For heavy, sharp-edged, or irregular components.
• Creped paper: For flexible wrapping, cushioning, and complex shapes.
• Static-dissipative paper: For electronic components and electrostatic-sensitive packaging.
• Linerboard: For lining or constructing cartons, crates, dividers, and rigid packaging.
• Specialty scavenging paper: For packages exposed to hydrogen sulfide or other specified corrosive contaminants.

How to Use Corrosion-Inhibiting Paper

Cortec® paper may be used to wrap a part, separate layers of components, line a shipping container, or create an enclosed protective package. For effective protection:

• Package metal parts when they are clean and dry.
• Remove dirt, salts, fingerprints, machining residue, and active corrosion.
• Use enough paper to provide appropriate coverage within the package.
• Position the treated side as directed for the selected product.
• Limit unnecessary air exchange by closing or sealing the package.
• Prevent prolonged exposure to rain, standing water, or uncontrolled outdoor conditions.
• Avoid contaminating the paper during handling and installation.
• Follow the current product instructions for recommended packaging distances and protection periods.

Does the Paper Need to Touch the Metal?

Direct contact can provide effective protection and is useful when paper is used for wrapping or interleaving. However, Cortec® VpCI® technology can also protect accessible metal surfaces within an enclosed package without covering every surface directly.

Package volume, airflow, barrier quality, paper quantity, metal type, temperature, and humidity can influence performance. Follow the recommendations for the specific paper and packaging configuration.

Paper Sheets, Rolls, and Custom Sizes

Corrosion-inhibiting paper is available in rolls and pre-cut sheets for different packaging operations. Rolls are useful for variable-sized components, production lines, and wrapping stations, while sheets provide consistent sizing for repetitive packaging.

When selecting a size, consider the dimensions of the part, number of layers, wrapping overlap, container size, packaging equipment, and expected material usage.
