Pearl paper structure and method for manufacturing the same

A method for manufacturing a pearl paper structure, comprising:

• preparing a middle layer material and a matte layer material;
• wherein the matte layer material includes a polypropylene, a polyethylene, fillers, and an initiator;
• and
• using the middle layer material and the matte layer material for a co-extrusion process to manufacture the pearl paper structure;
• wherein, in the co-extrusion process, the polypropylene, the polyethylene, and the initiator are reacted to form a polyolefin material;
• wherein the pearl paper structure includes a middle layer formed from the middle layer material and a matte layer formed from the matte layer material, the matte layer is disposed on the middle layer, and an arithmetic average roughness of the matte layer ranges from 0.5 μm to 1.3 μm;
• wherein, 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 %.
