CorriGlen
CorriGlen is an innovative and eco-friendly sign material. Made exclusively from 100% recycled polypropylene, CorriGlen provides a high-quality solution for all your signage needs while minimising environmental impact.
From its creation process to its end-of-life recyclability, CorriGlen is designed to meet the demands of today’s businesses looking to make a positive impact on the planet without sacrificing performance.
What is CorriGlen?
CorriGlen is a fully recycled sign board manufactured from end-of-life polypropylene shipping layer pads, which are sourced from recycled pre-consumer waste materials, such as offcuts and trimmings from virgin polypropylene. This means that every CorriGlen signboard starts its journey with materials that would otherwise be discarded, turning waste into a valuable resource for your business.
The signature white face and grey back of the CorriGlen board are created using a mixture of clear, white and coloured layer pad shipping waste, ensuring that the product is both visually appealing and environmentally responsible.
