When it comes to signs, two of the most popular types of plastic used are acrylic and polycarbonate sheets. These materials are easy to work with and can be cut into letters using common woodworking tools, such as saws and CNC milling machines. Acrylic sheet offers the advantages of superior UV stability and excellent light transmission. Another popular material used for signs is Dibond, which consists of two sheets of aluminum composite that cover a solid polyethylene core.
Polyethylene is the world's most common plastic and is used in a wide range of packaging and household products. This combination of metal and plastic makes the Dibond material both incredibly durable and visually appealing. Coroplast is another type of plastic that is often used for signs. This corrugated plastic sheeting is incredibly versatile and sign companies create a wide range of products with it, such as garden signs, golf signs, and real estate signs.
