Consumers often do not realize that products they depend on every day contain metal parts in need of corrosion protection before (and sometimes after) hitting the market. For example, automobiles are made of numerous metal components that may be manufactured in one part of the world and assembled in another.

Packaging Solution 02During the export trip, these parts need corrosion protection from extreme environmental conditions and humidity changes. Electronics, musical instrument strings, or expensive high tech medical diagnostic equipment such as MRIs or ultrasounds also require corrosion protection.

Cortec Corporation therefore offers a suite of packaging materials that protect metal goods from corrosion. Sold under the VpCI brand, these flexible packaging solutions use Vapor phase Corrosion Inhibiting Technology to safeguard metal components during shipment, when extreme humidity changes can put metals at risk for corrosion.

VpCI molecules incorporated into a packaging material work by evaporating into the air and forming a protective molecular layer on all metal surfaces inside an enclosed package. When the component reaches its destination, it can be unwrapped and used immediately without additional cleaning or degreasing. This is unlike many traditional methods, such as those in the auto industry, where parts are often dipped in petroleum-based rust preventatives that require cleaning and proper disposal before use of the part.

Cortec’s VpCI packaging suite comes in many shapes, sizes, and formats to suit specific needs. For the shipping of sensitive electronic components, the EcoSonic ESD Paper provides both corrosion and electrostatic discharge protection. When extra moisture protection is the required, EcoShield VpCI-144 Super Barrier Paper serves as a recyclable alternative to polyethylene and waxed papers.

Other flexible packaging options include Cortec’s VpCI-126 film, also available in multiple sizes and shapes, including small zip-lock bags for small parts and large shrouds to fit expensive medical diagnostic equipment. Other VpCI foams, emitters, and desiccant combinations add extra protection to the packaging suite as needed.

Cortec’s VpCI packaging is fully recyclable, fully repulpable and non-toxic.
