These event display boards have been created from a 3 layered polypropylene sheet. The outer layers are smooth and perfect for showing off high quality print, while the central layer is a cell structure giving great strength and rigidity. Lightweight. PVC free and 100% widely recyclable makes it a very environmentally friendly option. The board and the inks printed on it are waterproof so it can be used both inside and outside. These boards are 1200mm x 500mm, though this material can be cut to any shape or size.
