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.

A flat-bottomed bag is formed from a flexible sheet that initially is flat prior to being manipulated to form the bag. The sheet is a laminate of a first web and a second web laminated together by an adhesive layer disposed between the webs. The sheet defines a plurality of serially connected side wall panels collectively defining a vertically extending side wall of the bag, and a plurality of bottom panels respectively connected to the side wall panels at respective fold lines. The bottom panels are folded about the fold lines and are attached together to form a flat bottom wall configured to support the bag in an upright orientation. The adhesive layer is in a partial-coverage pattern that includes adhesive-free regions located along each fold line between each bottom panel and the respective side wall panel connected therewith.

An ion exchange resin bag 5 includes a bag body 51 and a reinforcing body 52. The bag body 51 has a bottom surface portion 511 that is provided at an end portion opposite to an end portion where an opening is provided and forms a bottom surface of the bag body, and a side surface portion 512 that is connected to the bottom surface portion 511 and forms a side surface of the bag body 51. The reinforcing body 52 has a first reinforcing portion 521 that is fixed to a boundary portion of the bottom surface portion 511 and the side surface portion 512, and a second reinforcing portion 522 that is connected to the first reinforcing portion 521 and fixed to at least a part of the side surface portion 512 and extends from the first reinforcing portion 521 toward the opening.

A woven laminated plastic bag having features that prevent leakage of contents out of the bag, or infestation of organisms into the contents of the bag is provided. In various aspects the bag can be fabricated from woven polypropylene and/or polyethylene layer which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing. The bag can also include a sealed closure that at least a portion of which can be easily peeled open with less force than the remainder of the sealed closure.
