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.

Abstract: The present invention relates to an infusion packet comprising a single sealed compartment (16), the compartment having a top (8) and a bottom (9) defined by two transverse seals (7) that are separated by a distance D, the distance D being in the range of 40 to 70 mm, wherein the compartment comprises at least one side gusset (15), the side gusset (15) consisting of two gusset panels (12) and three gusset creases (13, 14).

Abstract: Heat sealing apparatus for packaging machinery and particularly suitable for form, fill and seal packaging machinery. The heat sealing apparatus is for forming a continuous lengthways extending seal (29) on a web (18) of packaging material to be fed past it. The apparatus comprises a nozzle (50) connectable to a hot gas producer (62) which produces a flow of hot gas having a substantially constant temperature. The nozzle is mounted on a carrier (52) which is connected with a servo motor drive (56). The servo motor is controlled by a control system (48) so that in use it moves the nozzle relative to the web in accordance with variations in web feed velocity such that the flow of hot gas from the nozzle can apply a substantially constant heat to the web to form the seal (29). The apparatus allows a hot air producer which outputs hot air at a constant temperature and volume flow rate to apply a constant heat along the seal area despite variations in the web feed speed.

Abstract: A vertical form, fill and seal (VFFS) packaging machine comprising a pair of sealing jaws (12; 100; 200, 202; 302, 304) mounted directly or indirectly on parallel shafts (10; 102; 206, 208; 300) for rotation in opposite directions on opposite sides of the path of the packaging material (36; 118; 204, 308) so that the jaws engage the packaging material simultaneously on opposite sides to form successive horizontal seals, and stripping means comprising, in association with the sealing jaw on each side of the path of the packaging material, a pair of stripper carriers (22; 54; 66; 116; 222, 224, 226, 228; 314) mounted for rotation around the corresponding shaft at or near the respective ends thereof, or about an axis parallel to the shaft, a horizontal stripper bar (18B; 40A; 50A; 62; 110; 234; 310) mounted at its respective ends on the two stripper carriers and arranged to be movable with respect to the stripper carriers so that the stripper bar can engage the packaging film along a predetermined vertical strip
