Polystyrene Sign

Polystyrene Signs

Polystyrene signs are lightweight, flexible signs made with a 0.03 inch thickness and a smooth surface designed for high-quality printing. This material offers a clean appearance while remaining easy to handle and install. The thin, rigid profile makes polystyrene well suited for flat display applications where minimal thickness and weight are important. The smooth finish supports sharp graphics and clear text for close-view use. Polystyrene signage is ideal for: Rigid posters Menus and price boards Indoor and outdoor displays Temporary promotional signage Retail and point-of-sale applications Polystyrene provides good durability for short-term and medium-term use while maintaining flexibility for mounting on flat surfaces. It is a practical option for customers who need a professional look without the thickness or weight of heavier materials.
