The present disclosure relates to a card protective film, a production method thereof and a payment card, wherein the card protective film comprises a core layer of a biaxially oriented polyester film, a first connection layer and a printed bonding layer connected to a printed layer of a card substrate, as well as a surface processing layer with function(s) of thermal laminating release, thermal jointing and/or hot stamping; the printed bonding layer is connected to one side of the core layer through the first connection layer, and the surface processing layer is connected to the other side of the core layer. The card protective film can meet the technical performance requirements of the surface tension required by the surface processing of the payment card and also can meet the technical performance requirements of the release and the processing temperature required by the surface processing when the card is being laminated, and can provide better protection for the payment card or other cards, and the payment card or other cards made therefrom have higher transparency, higher surface and overall strength, higher temperature resistant grade, and thus have longer service life. |
