Abstract
The present invention relates to a pouch and a method for making the same. In the inventive method, which is adapted to produce pouches having a limited amount of fusible material, a heat-sealable cord is arranged on a web forming confronting side surface of each pouch. Those confronting side surfaces are fused by heating the heat-sealable cord. The present invention furthermore provides a pouch, in particular containing a brewable or extractable commodity such as tea, with a pocket defined between confronting side surfaces of a web. The pouch of the present invention can have a limited amount of fusible material as the confronting side surfaces are joined by solidified melt of a heat-sealable cord arranged in vicinity of at least one edge of the pouch.
