Polycarbonate ( PC ) Card uncoated Overlay- Smart Card Material for PC Card Production
Polycarbonate (PC) Card uncoated Overlay- Smart Card Material (Model: MUO-PC) is specially produced for PC card body lamination with printed sheets. It has such good features like strong lamination adhesion, excellent tensile strength, wear resistance and high temperature resistance. It is widely used in such cards as anti-fake IC cards, driving license card, transportation card and passport etc.
1.Polycarbonate ( PC ) Card uncoated Overlay- Smart Card Material - Introduction
Brief Introduction:
Polycarbonate (PC) Card uncoated Overlay is a new developed environment friendly product which could get excellent peel strength at high temperature. It provides superior aging resistance performance to other similar products, no color change and deformation after lamination.
Characteristics:
● Work well at high temperature,no color change with fluorescent ink.
● Abrasion resistant , prolong the life of cards.
● Environment friendly, no solvent or gas discharged.
