Pouch with a straw hole and method of manufacturing the same

Abstract

A method of manufacturing a pouch with a straw hole is provided that includes the steps of feeding a front-side film forming one panel of the pouch and a back-side film forming an other panel, from a roll of material, and punching a straw hole in one panel of the pouch. The method also includes the steps of feeding a seal material tape with a plurality of temporally punched portions, and each temporal punched portion has a size slightly larger than that of the straw hole, to a rear side of the panel with the straw hole. The method further includes the steps of temporally sealing the temporally punched portion of the seal material tape over the straw hole by aligning one temporally punched portion of the seal material tape with the straw hole, separating the temporally punched portion from the seal material tape and temporally sealing the temporally punched portion to the one panel. The method still further includes the steps of finally sealing the temporally punched portion to the one panel and sealing a side edge and a bottom edge of the one panel to the other panel to form the pouch.
