A packaging container includes an expandable plastic body having a front wall and a back wall, and a top, a bottom, and sides. Each side of the body has a gusset portion extending along a length thereof. Each gusset portion has gusset segments and a pair of adjacent gusset segments are joined along a common fold line. Each gusset segment has an inner surface and an outer surface. At least one of the gusset segments has an embossed section. The embossed section has a plurality of mounds protruding from one of the inner and outer surfaces and a plurality of depressions corresponding to the mounds within the other of said inner and outer surfaces. A roll for forming a packaging container, and method, are also disclosed.

A packaging container, comprising:
- an expandable plastic body having a front wall and a back wall, and a top, a bottom, and sides, each side of the body having a gusset portion extending along a length thereof, each gusset portion having gusset segments and a pair of adjacent gusset segments are joined along a common fold line, each gusset segment having an inner surface and an outer surface, at least one of the gusset segments having an embossed section, the embossed section having a plurality of mounds protruding from one of the inner and outer surfaces and a plurality of depressions corresponding to the mounds within the other of said inner and outer surfaces.
A roll for forming a packaging container, the roll comprising:
- an expandable plastic tube in a rolled-shape having a front wall and a back wall, the front and back walls meeting at sides of the expandable plastic tube, each side of the expandable plastic tube having a gusset portion extending along a length thereof, each gusset portion having gusset segments where a pair of adjacent gusset segments are joined along a common fold line, each gusset segment having an inner surface and an outer surface, at least one of the gusset segments having an embossed section, the embossed section having a plurality of mounds protruding from one of the inner and outer surfaces and a plurality of depressions corresponding to the mounds within the other of said inner and outer surfaces.
A method of forming a roll of flexible plastic material, the method comprising:
- forming a tubing from a sheet of the flexible plastic material, the tubing having side portions;
- forming a gusset in each of the side portions of the tubing;
- embossing at least a portion of each gusset to form mounds protruding from one surface of the gusset, and to form depressions in another surface of the same gusset;
- and
- winding the tubing into the roll of flexible plastic material.
