Form, fill, and seal bags and method of production

A form, fill, and seal bag comprising:

• first and second opposed sides, each of which is formed at least in part from first and second strips of a sheet material extending lengthwise of the bag from at least one end thereof, wherein at least one portion of the bag is located between strips of the sheet material and is formed from a strip of an open mesh material formed from 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 b ding portion of a relatively low melting point, the bonding portion of each filament being thermally bonded to filaments of at least one other layer, the open mesh material having a mass per unit area of no more than 20 g/m2 and a burst strength of at least 80 kPa, where burst strength is measured in accordance with ASTM standard D 3786, first and second end seams extending across one end of the bag and joining the first and second strips together with at least one layer of the open mesh material therebetween.

A form, fill, and seal bag comprising:

• first and second opposed sides, each of which is formed at least in part from a strip of a sheet material extending lengthwise of the bag from at least one end thereof, wherein at least one portion of the bag is located between strips of the sheet material and is formed from an open mesh material comprising 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 extends in machine and cross machine directions, and wherein the open mesh material has a mass per unit area of less than 30 g/m2 and a breaking elongation in at least one of the machine and cross machine directions of no more than about 50%, where breaking elongation is measured in accordance with ASTM standard D 5034;
• an end seam extending across one end of the bag and joining the first and second strips together with at least one layer of the open mesh material therebetween.
