Anti-bacterial and flame-retardant wall covering structure

An anti-bacterial and flame-retardant wall covering structure, comprising:

• a fiber substrate;
• a first polyolefin substrate formed on a surface of the fiber substrate;
• a second polyolefin substrate formed on another surface of the fiber substrate;
• and
• an anti-bacterial layer formed on a surface of the second polyolefin substrate away from the fiber substrate;
• wherein the anti-bacterial layer includes a fluorine-containing polymer;
• wherein each of the first polyolefin substrate and the second polyolefin substrate is formed from a polyolefin composition that includes a first polyolefin resin material, a second polyolefin resin material, and a flame-retardant additive material;
• wherein the first polyolefin resin material is a polyethylene resin, and the second polyolefin resin material is a polypropylene resin that includes a propylene block copolymer;
• wherein, based on a total weight of the polyolefin composition being 100 parts by weight, a content of the propylene block copolymer is not less than 5 parts by weight.
