Open mesh material and bags made therefrom

Abstract

An open mesh material includes filaments () that intersect one another. At least some of the filaments are 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 points of intersection. The material may be a non-woven fabric that contains at least two layers of weft filaments () that may be bordered on one or both sides by a layer of warp filaments (). When compared to other open mesh materials, the open mesh material disclosed herein has a superior combination of some or all of high strength, light weight, high dimensional stability, and openness. Also disclosed herein are articles can be made at least in part from the material including L-seam bags (), form fill and seal (FFS) bags (), and multi-substrate bags (). Methods of making those bags also are disclosed.
