Different types of materials are used to make graphic overlays in order to make the offer more visual appeal, clarity, accuracy, scratch resistant property, durability and so on. They are mainly manufactured using polycarbonate and polyester. They come in different types of finishes including gloss finish, matte finish, velvet finish and fine finish.

Many manufacturers of graphic overlay in Canada also use fiber which too offers excellent clarity and is scratch resistant to a large extent. This makes them ideal for different industries including those industries where the devices have to face harsh environmental conditions such as heat, humidity, rough handling, etc. Vinyl films are also used by many manufacturers nowadays as they are cost-effective. The disadvantage of vinyl overlay is that the material can be extremely solvent sensitive and easily succumb to corrosive chemicals.
