Cortec CorShield® Resealable and Static Shielding Bubble Bags

These bags are a clever packaging solution that brings together the physical cushioning of bubble wrap with advanced corrosion and static protection. What really sets them apart is their use of Vapor phase Corrosion Inhibitor (VpCI®) technology, which safeguards a variety of metals from rust and corrosion, while also providing static shielding to protect sensitive electronics, all within a convenient, resealable bubble bag format.

They achieve this dual protection by incorporating VpCI® technology directly into the bubble material. As soon as you seal an item inside, the VpCI® molecules vaporize and create a protective barrier on all exposed metal surfaces, preventing rust and corrosion. Simultaneously, the specialized film construction acts as a static shield, creating a "Faraday Cage" effect that guards against electrostatic discharge (ESD) from both internal and external sources.

Absolutely! Think of VpCI® as an invisible shield for your metals. When an item is enclosed in the bag, the VpCI® molecules evaporate and fill the air space around the metal. These molecules then settle on the metal surfaces, forming a very thin, molecular layer that blocks oxygen, moisture, and other corrosive elements from reaching the metal. The beauty of it is that this protective layer is entirely self-applying and doesn't leave any oily residue or film, so your items are ready for immediate use once removed from the bag.

Static shielding, in the context of these bubble bags, means providing a robust barrier against electrostatic discharge (ESD). It's more than just preventing static from building up on the bag itself; the bag actually protects the contents from external static charges and also prevents any static generated by the item inside from damaging other equipment. This is crucial for delicate electronic components that can be irreversibly harmed by even small static shocks.

Yes, these bags are designed to be reusable thanks to their resealable closure. To ensure they remain effective for multiple uses, it's important to inspect them before each use for any tears, punctures, or excessive wrinkling that could compromise their integrity. As long as the bag is intact and seals properly, the VpCI® protection and static shielding properties should remain active.

When shipping goods internationally, especially by sea, items are exposed to varying temperatures and humidity levels, which are prime conditions for corrosion. These bags are specifically designed to provide a continuous, active VpCI® barrier within the enclosed space, ensuring that metal components arrive at their destination completely rust-free, regardless of the journey's duration or environmental challenges.

During manufacturing, components often sit in various stages of completion, making them vulnerable to corrosion and damage. These bags offer convenient, on-demand protection for these in-process items. You can easily place partially manufactured goods inside, sealing them to prevent rust and physical damage, and then just as easily access them when they're needed for the next stage of production, without any messy cleaning required.

Absolutely, they are an excellent choice for long-term preservation. The VpCI® technology continuously protects against corrosion, and the bubble cushioning adds physical protection, making them ideal for storing expensive equipment, spare parts, or tools over extended periods. The resealable feature also allows for easy inspection and re-sealing, which is a significant advantage for long-term storage needs.

While they are fantastic for sensitive electronics, these bags are also highly effective for a wide range of other delicate components. This includes precision machined parts, optical instruments, finely crafted tools, and even medical devices that require both physical cushioning and protection from corrosion and potential static damage. Essentially, anything that benefits from impact protection and environmental safeguarding can find a home in these bags.

To maximize the protective benefits, it's crucial that the entire item you're protecting is fully enclosed within the bag. If any part of the item is sticking out, the crucial "Faraday Cage" effect for static shielding won't be complete, and the VpCI® vapor may not fully saturate the enclosed space. Therefore, measuring your items and choosing a bag size that offers ample room for complete enclosure is key.

One of the major advantages of Cortec's VpCI® technology is that it significantly reduces or eliminates the need for extensive surface preparation. Unlike traditional rust preventatives that often require cleaning or degreasing, you can typically place your metal components directly into the CorShield bags without prior surface treatment, making the process much quicker and more efficient.

Someone would choose these bags when they need a comprehensive solution that offers both superior corrosion protection for various metals and robust static shielding, along with physical cushioning. Standard anti-static bags might prevent static buildup but won't offer active corrosion protection, and regular bubble wrap lacks both static control and rust prevention. These bags provide a unique combination for truly sensitive or valuable items.

While these bags offer excellent standalone protection, they can certainly be part of a larger VpCI® preservation strategy. For extremely large or complex items, or in highly corrosive environments, they could be used in conjunction with VpCI® emitters or other VpCI® films to create an even more robust protective environment, though for most applications, the bags themselves are sufficient.

These bags find common utilization across a variety of industries that handle sensitive and valuable metal components. This includes electronics manufacturing, automotive, aerospace, defence, precision engineering, telecommunications, and general manufacturing where rust prevention and static control are critical during storage and shipment.

These bags drastically simplify the packaging process by combining multiple protective functions into one easy-to-use solution. You no longer need separate anti-corrosion treatments, desiccants, or additional cushioning materials. Just place the item in the bag, seal it, and you're done, saving time, labor, and material costs while ensuring superior protection.

The VpCI® technology embedded in these bags is designed to protect a wide array of metals, including carbon steel, aluminum, copper, brass, silver, and stainless steels. This multi-metal protection ensures versatility for various components you might need to package.

No, a significant benefit of these bags is that the VpCI® technology works without leaving any film or residue on the packaged items. This is incredibly advantageous because it means the components are ready for immediate use, painting, welding, soldering, or any other post-packaging process without the need for cleaning or degreasing.

These Cortec CorShield bags are engineered to meet stringent industry standards for both corrosion protection and static control. For corrosion, they are NACE TM0208-2018 qualified and meet German TL-8135-002 standards. For static shielding, while specific standards for this exact product on the linked page aren't detailed, Cortec's broader static dissipative films often conform to MIL-PRF-81705D (Type II), which is a key indicator of their static control capabilities.

No, a key advantage of Cortec's static dissipative technology, like that found in these bags, is that its properties are humidity independent. This means their ability to prevent static charge generation and dissipate static effectively is not reliant on the presence of moisture in the air, ensuring consistent protection across various environmental conditions.

The resealable feature provides significant functionality beyond just easy access. It allows for convenient inspection of the contents without compromising the protective environment, enables partial removal of items if needed, and facilitates reuse of the bag, thereby extending its lifespan and offering greater flexibility in inventory management.

By embedding VpCI® technology directly into the bag material, these bags effectively replace the need for traditional, often messy and hazardous, rust preventatives like oils, greases, or desiccants. This means no more applying or removing messy coatings, which enhances worker safety, reduces chemical waste, and simplifies the entire corrosion protection process.

The semi-transparent nature of these bags is a practical benefit, allowing for easy visual identification of the contents without having to open the bag. This saves time in inventory management, simplifies quality checks, and helps prevent unnecessary exposure of sensitive items to the external environment.

For electronic components, both corrosion and electrostatic discharge are major threats to their operational lifespan. By actively preventing corrosion and providing a robust static shield, these bags protect components from two primary causes of premature failure, thereby significantly increasing their longevity and ensuring they perform optimally when finally put into use.

These bags are specifically designed to prevent damage from triboelectric charge generation, which is static electricity created through friction when certain materials rub together. This is crucial when handling and transporting static-sensitive components, as the bag's material itself is static dissipative, preventing charges from building up on its surface and discharging onto the sensitive items inside.

The combination is paramount because sensitive components are often vulnerable to both environmental degradation (like corrosion) and physical damage (like impact or vibration). A solution that offers both, like these bubble bags, provides comprehensive safeguarding, ensuring that the components arrive in perfect condition, protected not only from rust but also from the knocks and bumps of transit and handling.
