The invention discloses a sealing packing box with better sealing property, hygiene and environment friendliness. The sealing packing box is formed by a box cover and a box body with an injection molding ring; the box cover is formed by injection molding of a LDPE material, and a reversed buckling position is designed at the inside of the edge of the box cover; a seal ring made of a soft rubber is arranged at the bending position of the inner wall of the box cover; the box body is an integral product formed by dual processes of blistering and injection molding; the box body part is molded by performing injection molding on three to five layers of co-extruding materials; the opening of the box body is bent outwards and is properly lengthened to form a box opening edge material; the injection molding ring is formed on the box opening edge material by performing the injection molding process on a PP (propene polymer) material. After the box cover covers, the inner side of the box cover and the injection molding
