Heat-seal tea filter paper and tea bag

The utility model belongs to the technical field of new special paper materials, and particularly relates to heat-seal tea filter paper and a tea bag. The heat-sealing tea filter paper comprises base paper and a heat-sticking coating layer, food-grade thermoplastic polyolefin or polylactic acid emulsion is coated and dried on one side or two sides of the base paper, and the base paper part, which is not permeated into the base paper, of the food-grade thermoplastic polyolefin or polylactic acid emulsion forms a base layer; the base paper part infiltrating into the base paper forms an emulsion-containing permeable layer, a surface layer is also formed on the surface of the base paper, and the surface layer and the emulsion-containing permeable layer jointly form the hot sticking coating layer. The heat-sealing tea filter paper is good in comprehensive performance, the base paper manufacturing method is simple, the heat-sticking coating layer is convenient to coat, production adaptability is high, indexes of th
