Synthetic Mesh Reinforced Multilayer Material and Bags Made Therefrom

摘要

A reinforced multilayer material includes a mesh material covered on at least one side, and possibly both, by a layer of a resinous film material. The mesh material includes 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 least some points of intersection. The multilayer material has a mass per unit area of less than 9.0 oz/yd2 and a bursting strength to mass per unit area ratio of at least 9.0 lbs/(oz/yd2), where bursting strength is measured in accordance with ASTM-D37 86. A bag is provided that is made at least in part from a multilayer material having at least some of the characteristics described above.

1. A reinforced multilayer material comprising:
a layer of an open mesh material having first and second opposed surfaces, the open mesh material including 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 in at least some points of intersection; and a layer of film material applied to the first surface of the layer of open mesh material, wherein the multilayer material has a mass per unit area of less than 9.0 oz/yd2 and a bursting strength to mass per unit area ratio of at least 9.0 lbs/(oz/yd2), where bursting strength is measured in accordance with ASTM-D37 86.
