ABSTRACT:
The invention discloses a 5-layer co-extruded biaxial-oriented polypropylene synthetic paper which is a 5-layer laminated structure with thickness between 30–300 μm comprising the uppermost layer (A) of paper sheet or resin, the second layer (B) of paper sheet or resin, the intermediate foamed layer (C), the forth layer (D) of paper sheet or resin and the bottom layer (E) of paper sheet or resin which is to improve the rigidity and stiffness covering power, strength between layers, glossiness of paper surface, paper thickness and the printability of the conventional synthetic paper.
