Abstract
A bag formed of a sheet material adapted to be filled with contents and opened at the top for taking out the contents. The bag has fused joints along the lateral edges thereof.

A method of producing a bag, comprising:
- forming a bag of sheet material;
- forming a tubular holder in an inner side of a lateral edge of the bag to hold a plastically deformable vertical wire-like member;
- and
- inserting the vertical wire-like member into the tubular holder;
- heat sealing the tubular holder to form a fused joint such that said vertical wire-like member is disposed along the lateral edge inside said tubular holder,
- wherein the tubular holder is positioned at a top end, at a bottom end, and on at least one side of the vertical wire-like member so as to leave a space from the tubular holder.
