ESD cardboard

Market Leading Corstat.

Conductive packaging and handling

Corstat conductive coating is the industry standard for creation of static safe packaging. This ESD cardboard provides a buried shielding layer, creating a Faraday cage that offers a safe, controlled path to ground for static charges.

It is completely safe to handle without the need for protective equipment, is easily converted on standard machinery and is fully recyclable. There is also a wide range of pre-fabricated products available from an extensive stock holding.

01: What is Corstat ESD Cardboard?

Offer your customers industry standard anti static protection provided by Corstat

Corstat, exclusively from GWP, is well known as the ESD industry standard for conductive corrugated board and is used to create cutting edge anti-static and ESD packaging solutions.

Engineers and manufacturers alike have relied on its consistency, ease of use and reliability for use in their ESD sensitive applications.

Corstat® is the cleanest, longest lasting conductive corrugated board in the marketplace today. By providing a buried shielding layer and a sealed surface, it creates an effective, controlled path to ground for static charge and therefore a safe environment for static-sensitive devices.

High performance and reliability is guaranteed thanks to in-house production in an ISO 9002 environment, it offers consistent appearance and performance regardless of end application or product use, and is fully bio-degradable and environmentally friendly. It is also safe for handling, containing no harmful chemicals.

Happy customers of GWP Coatings

With proven static protection & guaranteed for 10 years, Corstat has been specified by virtually every blue chip / OEM electronics manufacturer since the early days of silicone technology. Its’ buried shielding layer & sealed surface offer a controlled, safe path to ground.

02: Advantages of Corstat.

Improve your efficiency and margins using Corstat

A common concern among sheet plants is that anti –static materials can be difficult to process and fabricate.

Fortunately however, Corstat coated board can be easily converted using standard machinery.

This allows you to maintain efficient manufacturing processes, which in turn leads to cost savings for your sheet plant and improved margins. This also allows you to offer exceptionally competitive pricing, aiding repeat business too.

Another significant benefit of using Corstat conductive coating is that it is completely safe and inert. As such, it requires no PPE or specialist handling measures to ensure that your workforce remains safe.

Not only does this create significant savings in conversion times, it also reduces the need to procure additional PPE equipment, ultimately saving you money.

Anti static packaging
When combined with conductive or anti static foam, Corstat coated board provides unrivalled protection for electronics

On a similar note, Corstat is environmentally friendly and contains no heavy metals or aromatics. As well as reducing the need for PPE as mentioned above, this also means that board coated with Corstat can be easily recycled and so incurs no additional recycling and disposal costs.

The coating is also biodegradable and so can help support your plant’s environmental obligations.

Features that increase efficiency of your operations

  • Biodegradable and eco friendly, with no requirement for specialist / costly disposal methods
  • Completely inert (no halogenated compounds, aromatics etc.) to eliminate need for PPE
  • Can be easily converted on standard machinery, including the ability for overprinting
  • Lead times as short as 48 hours minimises storage requirements and associated costs

03: Benefits for ESD Packaging Users.

The industry standard for anti static packaging

Corstat coated board is used to create long lasting, durable and reliable packaging for delicate components and any item at risk from static electricity.

Used by the majority of the large electronic companies in the USA and UK, Corstat conductive coating creates a faraday cage in order to protect the items within.

This, in effect, sees any static charges channelled around the cartons’ exterior, creating a safe path to ground.

The obvious benefit provided by these properties is a vast reduction in items damaged during transit or storage, which can in turn lead to hugely significant cost savings.

Another key benefit you can offer to your customers by utilising Corstat is that of cost. Being significantly lower in cost than moulded plastic alternatives, Corstat also offers a 10 year shelf life to ensure long lasting performance.

This is in addition to the benefits of using standard corrugated packaging (low cost, good strength, light weight etc.).

Value for money for you and your customers

  • Exceptional conductive performance for protecting electronics and minimising costs of damage
  • Buried shielding layer creates an effective, reliable “Faraday Cage” effect for highest protection
  • 10 year shelf live ensures longevity and ongoing performance
  • A cost effective alternative to moulded plastic to further reduce costs

04: Additional Features / Benefits

Additional benefits of using conductive corrugated board

Use of Corstat coated board can offer a number of other benefits for your business.

This can be as simple as attracting new customers through an increased product range, or winning more business from your existing customers through upselling and cross-selling.

With Corstat being manufactured to ISO approved standards, the resulting packaging you produce will also be of the highest quality, further enhancing your reputation and aiding repeat business.

Besides this, Corstat coated board can be supplied on short lead times (usually twenty-four hours) due to our large stock holding. This enables you to supply your customers quickly and efficiently and become more responsive to urgent enquiries.

Anti static cardboard
The range of products that can be fabricated using Corstat is surprisingly diverse, as it can be converted on most standard equipment

Also being available in both high and low runs, (with a minimum order of 200 sq.m), it allows you to offer flexible MOQs and minimise storage space through not having to over-order raw materials.

Finally, you can also offer your customers a wide selection of pre-fabricated conductive packaging products from a vast stock-holding held at GWP Coatings.

This not only reduces lead times still further, but allows you to provide products that have been widely and successfully used throughout numerous industries for over twenty-five years.

These products are also supplied on a completely confidential, trade agreement.
