Bottom filled, bottom-gusseted bag and method of making the same

A method of forming a bottom-fillable, bottom-gusseted bag, comprising:

• supplying a sheet of material in a longitudinal direction;
• folding said sheet to form a bag-forming structure including first and second opposing body panels and a bottom-gusset joining said first and second body panels, said bag-forming structure including an open end opposite said gusset, said gusset including first and second gusset panels foldably connected to each other and foldably connected to said respective first and second body panels;
• slitting one of said second gusset panel and said second body panel along a transverse slit to provide a transverse fill opening through which a product can be inserted into said bag-forming structure;
• and
• applying a pair of transverse seals to said bag-forming structure to form an individual bag.

A bottom-fillable, bottom-gusseted bag comprising:

• a bag-forming structure including first and second opposing body panels joined along a pair of opposing transverse seals and a bottom-gusset extending between said transverse seals, said bag-forming structure including an open end opposite said bottom-gusset, said bottom-gusset including first and second gusset panels foldably connected to each other and foldably connected to said respective first and second body panels;
• a zipper attached to said first and second body panels along said open end;
• a slider slidably mounted to said zipper for opening and closing said zipper;
• and
• a transverse slit disposed proximate to a fold line foldably connecting said second gusset panel to said second body panel to provide a fill opening through which a product can be inserted into said bag-forming structure.
