Open mesh material and bags made therefrom

An open mesh material extending in machine and cross machine directions, the open mesh material comprising:

• layers of individual filaments that intersect one another, at least some of the filaments being composite filaments having a carrier portion of a relatively high melting point and a bonding portion of a relatively low melting point, the bonding portion of each composite filament being thermally bonded to other filaments at at least some points of intersection, wherein the open mesh material has a mass per unit area of less than 30 g/m2 and a strength to mass ratio in at least one of the machine and cross machine directions of at least 2.67 N/(g/m2), where strength is measured in accordance with ASTM standard D 5034.
