    摘要: Provided is a lightweight mesh nonwoven fabric having excellent adhesiveness between uniaxially oriented bodies, excellent low-temperature heat sealability, and high strength. A mesh structure 1 includes two or more uniaxially oriented bodies 2, 3; which include a thermoplastic resin layer and a linear low-density polyethylene layer laminated on at least one side of the thermoplastic resin layer; the mesh structure is produced by laminating or weaving the uniaxially oriented bodies through the linear low-density polyethylene layer in such a way that orientation axes L, T of the uniaxially oriented bodies cross; and the mesh structure has properties of: (1) a fiber weight per unit area of 5 to 70 g/m2, (2) a thickness of the linear low-density polyethylene layer of 2 to 10 μm, (3) an adhesive force between the uniaxially oriented bodies of 10 to 60 N, and (4) a tensile strength of 20 to 600 N/50mm.
