What is ESD?
Let’s start at the beginning and explain what ESD actually is.
ESD stands for electro static discharge. This is the release of static electricity when two objects come into contact. This is something you may have experienced yourself – for example when you get an electric shock after walking across a carpet and touching a metal doorknob.
ESD first requires a build-up of an electrostatic charge, which can occur when two different materials rub together. When this happens one material becomes positively charged, whilst the other becomes negatively charged. With the positively charged material now having an electrostatic charge, this can be transferred when it comes into contact with other specific materials.
Although often invisible, this electrostatic discharge generates a huge amount of heat.
Why is ESD a problem?
But why should this matter? Well, when the ESD is released onto an electronic device, the intense heat can melt, vaporise, or otherwise damage the intricate parts of the device, causing it to fail.
This is why ESD packaging – such as Corstat® manufactured by GWP – is frequently used. This creates a “Faraday cage” which channels any ESD around the outside of the packaging container, protecting the sensitive electronics inside.
Further anti-static or static dissipative materials, such as foam, can be used to provide additional protection.
What is a Faraday Cage?
In simple terms, a Faraday cage or shield is characterised as a sealed enclosure created by materials which are electrically conductive. Usually the outer layer will block external electric fields both static and non-static protecting the item or device inside.
Made from any closed shape, these cages can either be made purely from conductive material or made from non-conductive material and then wrapped in conductive materials. They are frequently used to protect a variety of electronic equipment from electrostatic discharges.
How a Faraday cage works
Using this for Packaging? Whilst a Faraday cage is frequently portrayed as literally a metal mesh or cage, many forms of packaging provide this type of protection.
The well-known Corstat® coated fibreboard for example, is effectively a carbon coating which allows the creation of the Faraday cage. Corriplast® and SSI Schaefer products, both have carbon impregnated directly into the Polypropylene material during manufacture.
It must be noted however that simply using a conductive material will not create a Faraday cage – the structural design of the packaging also plays a key role.
Going into greater detail, how electricity works in conductors is the key to understanding how a Faraday cage works.
Metals have negatively charged particles or electrons in them. Without electrical charge the conductor will have the same amount of positive and negative particles.
When an external object with electrical charge approaches the conductor (the metal) the particles separate. Any electrons with an opposite charge to the external object are drawn to that object, but any electrons with the same charge are repelled and move away from the object.
The negative and positive particles then end up on the opposite sides of the conductor, the following process is a redistribution of charges, which, results in an opposing electrical field that cancels out the field of the external object.
The opposing field shields the interior from exterior static charges therefore protecting the item inside.
Working with GWP Conductive
How your business can benefit
All of GWP’s stock products have been designed to complement each other while working seamlessly with the majority of standard racking and shelving systems which are typically found within ESD controlled workspaces.
They are therefore perfect for a huge range of handling and storage applications where ESD performance is of paramount importance.
This is in addition to the range of benefits provided by Corstat® and Corriplast®, such as their durability and strength.
The range of stock products also offers potential cost savings in comparison with custom designed products. By eliminating the need for both design time and tooling, the cost of the standard ranges is often significantly cheaper than bespoke options.
Custom anti-static packaging
Besides keeping an extensive stock holding of these products – which allows for next day delivery in the vast majority of cases – GWP take pride in being one of the very few companies in the UK to offer a genuinely bespoke design service.
This means that, if one of the standard Conductive products is not 100 percent perfect for your specific application, GWP Conductive can create a bespoke solution tailored to your exact needs and requirements.

What does anti-static actually mean?
Anti-static is used as a generic term for any material which allows the flow of electrons, meaning it can actually be applied to both dissipative and conductive items. There are actually a number of other terms used when discussing anti-static packaging, such as dissipative, conductive, insulative and so on.
Is conductive packaging the same as anti-static?
Conductive materials provide a low electrical resistance, allowing electrons to flow across or through them to ground. They would typically have a surface resistivity less than 1 x 10⁵ Ω/sq. or a volume resistivity less than 1 x 104 Ω-cm. They can be used in ESD safe packaging if the pack creates a Faraday cage effect.
What is static dissipative?
Static dissipative materials allow the charges to ground more slowly and in a more controlled manner when compared with conductive materials. Dissipative materials have a surface resistivity equal to or greater than 1 x 10⁵ Ω/sq. but less than 1 x 1012 Ω/sq.
Can insulative materials be used for ESD safe packaging?
Finally, insulative materials prevent or limit the flow of electrons across or through them. They have electrical resistance and are difficult to ground, and unlike anti-static material, charges will remain on them for a considerable time. Insulative materials are defined as those having a surface resistivity of at least 1 x 1012 Ω/sq. or a volume resistivity of at least 1 x 1011 Ω-cm.
Can I source custom anti-static packaging from GWP?
Whilst many other packaging suppliers will offer custom designed anti-static packaging, these are nearly always created by designers with little or no experience of creating successful ESD safe solutions. With over 25 years’ experience and a dedicated anti-static design team, you can be certain that any custom item GWP create for you will provide levels of performance and protection that exceed your expectations.
What products are available from GWP?
Being the UK leaders in the manufacture and supply of conductive and ESD safe packaging, GWP are able to offer you products which are exclusive to us in the UK market. This includes products manufactured in house by GWP (such as Corstat®) as well as leading branded ranges such as the SSI Schaefer collection of ESD safe totes, bins, and boxes.
