A packing material for packing food products, the packing material formed of a mesh body (8, 9, 10, 114, 318) produced by a method for producing the mesh body (8, 9, 10,114, 318), comprising the steps of: laminating crosswise or weaving uniaxially oriented bodies (1, 6, 7, 110, 210, 410) made of a thermoplastic resin so that their orientation axes (1a, 6a, 7a) cross each other, and entirely surface-bonding contact portions of adjacent uniaxially oriented bodies (1, 6, 7, 110, 210, 410) via bonding layers (5, 5', 5") thereof to form the mesh body (8, 9, 10, 114, 318); and applying an embossing processing, which is a surface-roughening processing, to a surface of the mesh body (8, 9,10, 114, 318), wherein the step of entirely surface-bonding the contact portions of adjacent uniaxially oriented bodies (1, 6, 7, 110, 210, 410) via bonding layers (5, 5', 5") thereof includes feeding uniaxially oriented bodies (1, 6, 7, 110, 210, 410) to be bonded between a hot cylinder (113a, 317a) of which the circumferential surface is a mirror surface and a mirror surface roll (113b, 113c, 317b, 317c), and applying to these uniaxially oriented bodies (1, 6, 7, 110, 210, 410) a nip pressure by the hot cylinder (113a, 317a) and the mirror surface roll (113b, 113c, 317b, 317c), wherein the step of applying the embossing processing to the surface of the mesh body (8, 9, 10, 114, 318) includes feeding the mesh body (8, 9, 10, 114, 318) between a heated embossing roll having a plurality of circular convex portions on a surface thereof and a rubber roll, and applying to the mesh body (8, 9, 10, 114, 318) a nip pressure by the embossing roll and the rubber roll, and wherein the mesh body (8, 9, 10, 114, 318) further comprises: surface-bonded portions formed by entirely surface-bonding contact portions of adjacent uniaxially oriented bodies (1, 6, 7, 110, 210, 410) via bonding layers (5, 5', 5") thereof; and circular concave portions formed on a surface of the mesh body (8, 9, 10, 114, 318) by the embossing processing. laminating crosswise or weaving uniaxially oriented bodies (1, 6, 7, 110, 210, 410) made of a thermoplastic resin so that their orientation axes (1a, 6a, 7a) cross each other, and entirely surface-bonding contact portions of adjacent uniaxially oriented bodies (1, 6, 7, 110, 210, 410) via bonding layers (5, 5', 5") thereof to form the mesh body (8, 9, 10, 114, 318); and applying an embossing processing, which is a surface-roughening processing, to a surface of the mesh body (8, 9,10, 114, 318), wherein the step of entirely surface-bonding the contact portions of adjacent uniaxially oriented bodies (1, 6, 7, 110, 210, 410) via bonding layers (5, 5', 5") thereof includes feeding uniaxially oriented bodies (1, 6, 7, 110, 210, 410) to be bonded between a hot cylinder (113a, 317a) of which the circumferential surface is a mirror surface and a mirror surface roll (113b, 113c, 317b, 317c), and applying to these uniaxially oriented bodies (1, 6, 7, 110, 210, 410) a nip pressure by the hot cylinder (113a, 317a) and the mirror surface roll (113b, 113c, 317b, 317c), wherein the step of applying the embossing processing to the surface of the mesh body (8, 9, 10, 114, 318) includes feeding the mesh body (8, 9, 10, 114, 318) between a heated embossing roll having a plurality of circular convex portions on a surface thereof and a rubber roll, and applying to the mesh body (8, 9, 10, 114, 318) a nip pressure by the embossing roll and the rubber roll, and wherein the mesh body (8, 9, 10, 114, 318) further comprises: surface-bonded portions formed by entirely surface-bonding contact portions of adjacent uniaxially oriented bodies (1, 6, 7, 110, 210, 410) via bonding layers (5, 5', 5") thereof; and circular concave portions formed on a surface of the mesh body (8, 9, 10, 114, 318) by the embossing processing. surface-bonded portions formed by entirely surface-bonding contact portions of adjacent uniaxially oriented bodies (1, 6, 7, 110, 210, 410) via bonding layers (5, 5', 5") thereof; and circular concave portions formed on a surface of the mesh body (8, 9, 10, 114, 318) by the embossing processing.
