05: About GWP Conductive.

A genuine anti-static packaging manufacturer

Regardless of where you are, you can access GWP Conductives’ full range of anti static packaging products.

This is achieved by selling exclusively through a Europe wide network of distributors, all of which can offer you advice and guidance on the best product for your application.

The entire collection of Corstat coated cardboard, Corriplast and SSI Schaefer ranges are available through these distributors, meaning it is easier than ever to source your perfect ESD safe packaging.

SSI Schaefer exclusive range
GWP Conductive are the only UK stockists and distributors of the SSI Schaefer range of conductive totes and bins

However, if a stock product is not 100 percent perfect for your specific product, market or application, then GWP Conductive can design and manufacture you a completely bespoke solution.

This is achieved through having an experienced design team with a wealth of knowledge about static behaviour, as well as a modern, well equipped production facility. This means that not only do you get exactly what you need, but you also benefit from the highest possible quality too.

All this is complemented by a dedicated customer service team, free, no obligation quotes and completely impartial advice.
