Conductive cardboard packaging
If you need conductive cardboard packaging, there is only one option – Corstat®.
Corstat® coating and the products manufactured with it are widely regarded as the industry standard for ESD (electrostatic discharge) safe packaging. Its buried shielding layer creates a Faraday cage effect, channelling static around the pack’s exterior to protect the contents. It is also cost-effective, environmentally friendly, and has a 10-year lifespan.
GWP Conductive are the sole UK manufacturer of Corstat® boxes, packaging and products. By coating corrugated material and then converting it in-house, we can offer you both a wide range of stock conductive boxes and products and custom-designed solutions. Our ESD specialists can also provide free, impartial advice on the best option for your business.

General
Corstat® is the cleanest, longest-lasting conductive corrugated material in the marketplace today. It is used extensively in both stock 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, thereby providing a safe environment for static-sensitive devices. It does this – in combination with specific structural designs – by creating a Faraday cage effect.
Corstat® coated material is fully recyclable, minimising disposal costs, and safe to handle with no need for specialist equipment or PPE. It is also fully biodegradable and recyclable, whilst it does not contain any heavy metals, aromatics or halogenated hydrocarbons.

FAQs
What is Corstat®?
Corstat® is effectively a corrugated cardboard material with a specialist coating applied (the Corstat® element). This coating makes the material – and any packaging or handling products manufactured from it – potentially resistant to electrostatic discharge.
Are Corstat® products environmentally friendly?
Corstat® is fully biodegradable and recyclable, making disposal quick and easy for your clients, customers, or end users. The material also contains no heavy metals, aromatics, or halogenated hydrocarbons.
Is Corstat® safe to handle and use?
In addition to being fully recyclable and biodegradable, Corstat® is also completely inert. As a result, your staff or production operatives can safely handle any Corstat® box or products without specialist equipment or personal protective equipment (PPE).
Is Corstat® resistant to moisture and liquids?
Due to the nature of the corrugated material used in Corstat® products, they offer only limited resistance to moisture, oils, and other liquids. However, it is possible to manufacture the majority of Corstat® products 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® ESD boxes and products, the full range of stock lines, including ESD cardboard boxes, bins, trays, dividers and more, is available from a Europe-wide network of specialist distributors.

Why work with GWP Conductive?
Put simply, GWP Conductive is more than just another ESD cardboard box supplier.
Firstly, we manufacture the vast majority of products we sell. This includes not only Corstat® (we coat the corrugated board in–house and manufacture the finished packaging) but also Corriplast®. As a result, we have complete control over the quality of the product you receive.
Secondly, GWP are the only UK stockholder of SSI Schaefer conductive products, effectively giving you the broadest range of ESD safe packaging under one roof.
Thirdly, we have an experienced design team with extensive knowledge specific to anti-static packaging. So, if none of the stock range of ESD packaging boxes or products are just right, you can choose to have one designed and manufactured to your exact requirements.
And as well as all of this, you can take delivery of your (standard) products in under 48 hours, can benefit from the best UK prices, and have a dedicated account manager assigned to your business to ensure your expectations are not just met, but completely exceeded.
