Structure of Standard Plastic Cards
Standard Plastic cards usually consist of four layers. Two printed PVC-foils for the front and back, and one protection overlay for each side. All layers are pressed together with the help of pressure and heat in so called laminators and thus form a compact card body. During the process of lamination, the surface structure of the outer protection overlay is determined by the texture of the lamination-plates which press the card body from both sides. If the plates are glossy, the card surface will be glossy, if they are matt, so will be the card.
In order to equip plastic cards with additional data carriers, further layers can be added to the structure; you can find out more about this under Structure of RFID-Cards.
Build-up of Varnished Cards
Aside from the classic multi-layered cards made of PVC, there are cheaper alternatives. These UV-varnished mono-cards consist of only one PVS foil which is printed on both sides and protected by a UV-varnish. Therefore, these cards are especially suited for short-time or single use.
