Further Information

Additional details on Corstat® conductive fibreboard packaging

Corstat® is the cleanest, longest-lasting conductive corrugated material in the marketplace today. It is used extensively in both stock conductive / anti-static packaging products and bespoke ESD safe items.

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. It does this – in combination with specific structural designs – by creating a Faraday cage effect.

Corstat® conductive board coating is consistently manufactured, within an ISO 9002 approved environment, to high specifications which are accepted worldwide.

It is also fully recyclable, minimising disposal costs, and safe to handle with no need for specialist equipment or PPE. Corstat® conductive board coating is fully biodegradable and recyclable, whilst it does not contain any heavy metals, aromatics or halogenated hydrocarbons.

And finally, there is also a wide range of stock products, plus the option for fully bespoke items.

Corstat® FAQs

Common questions regarding conductive Corstat® material / products

Please see below for a number of questions covering Corstat® material, and the products manufactured from it.

If you cannot find the information you need however, please contact a member of the GWP team on 01793 754 457 or email We’ll be happy to help!

What is Corstat®?

Corstat® is effectively a corrugated cardboard material (often referred to as fibreboard) which has been coated with a specialist coating (the Corstat® element). This coating makes the material – and any packaging or handling products manufactured from it – potentially resistant to electrostatic discharge (ESD)

What products can be made from Corstat®?

Almost any form of corrugated packaging can be made using Corstat® instead. However, specialist structural design must be employed to realise the full anti-static properties of the material (effectively the packaging needs to create a Faraday cage effect to channel the static around the outside of the box).

Are Corstat® products environmentally friendly?

Corstat® is full biodegradable and recyclable. This makes disposal by your clients, customers, or end users quick and easy. The material also contains no heavy metals, aromatics, or halogenated hydrocarbons.

Is Corstat® safe to handle / use?

Besides being fully recyclable and biodegradable, Corstat® is also completely inert. This means that your staff or production operatives can safely handle any Corstat material or products with no requirements for specialist equipment or personal protective equipment (PPE).

Is Corstat® resistant to moisture / liquids?

Due to the nature of the corrugated material which forms the base of Corstat® products, they only provide limited resistance to moisture, oils, and other liquids. However, the majority of Corstat® products can be manufactured from conductive Correx® (Corriplast®) which provides these properties if required.

Where can I buy Corstat® packaging products?

Whilst GWP Conductive are the sole UK manufacturers of Corstat® products, the full range of stock lines are available for a Europe wide network of specialist distributors. Please click here to find your nearest stockist.
