Abstract
A pearl paper structure and a method for manufacturing the same are provided. The pearl paper structure includes a middle layer and a matte layer. The matte layer is disposed on the middle layer. A material of the matte layer includes a polyolefin material and fillers. The polyolefin material is formed by reacting a polypropylene, a polyethylene, and an initiator. Based on a total weight of the matte layer being 100 wt %, an amount of the polypropylene ranges from 20 wt % to 65 wt %, an amount of the polyethylene ranges from 30 wt % to 75 wt %, and an amount of the fillers ranges from 5 wt % to 10 wt %. An arithmetic average roughness of the matte layer ranges from 0.5 μm to 1.3 μm.
