Document Type and Number:
WIPO Patent Application WO/2018/028571
Kind Code:
A1
Abstract:
Disclosed are a card protective film, a manufacturing method therefor and a payment card. The card protective film comprises a core layer (19) formed by a bi-oriented stretching polyester thin film, a first connection layer (11), a printing adhesion layer (13) connected to a printing layer of a card base material, and a surface machining layer (12) provided with the functions of thermal laminating release, hot press lamination and/or hot stamping. The printing adhesion layer (13) is connected to one face of the core layer (19) by means of the first connection layer (11), and the surface machining layer (12) is connected to the other face of the core layer (19). The card protective film can satisfy the technical performance demands of surface tension in surface machining of the payment card and also the technical performance demands of release and machining temperature in surface machining when laminating the card. The card protective film can provide better protection to a payment card or other cards. A payment card or other cards, manufactured using the card protective film, have higher transparency, higher surface and overall strength and a higher level of temperature resistance and further have a longer service life.
