The present invention is directed to a side-sealed open mesh fabric bag having one or more multi-layer seam structures. At least one side seam of the bag comprises a plurality of folded layers of the bag's fabric bonded together within a seam structure by a plurality of seal portions. At least one of those seal portions is a sacrificial seal configured to at least partially give from the seam structure, whilst one or more other seal portions of the seam structure remain intact. The sacrificial seal provides the bag with volumetric flexibility, whilst the remaining seam structure provides an improved seam strength.
The present invention is directed to a side-sealed open mesh fabric bag (100) having one or more multi-layer seam structures (130a, b). At least one side seam of the bag comprises a plurality of folded layers of the bag's fabric bonded together within a seam structure by a plurality of seal portions (132 a,b). At least one of those seal portions is a sacrificial seal configured to at least partially give from the seam structure, whilst one or more other seal portions of the seam structure remain intact. The sacrificial seal provides the bag (100) with volumetric flexibility, whilst the remaining seam structure provides an improved seam strength.

The present invention is directed to tamper-evident mesh material, methods of manufacture therefor, and tamper-evident bags manufactured therefrom. The tamper-evident mesh material of the present invention may be used, for example, in the manufacture of a variety of tamper-evident security bags for use in applications where it is desirable to detect any traces or evidence of tampering with or of unauthorized access to the contents of the bag.
