Abstract
To provide a heat-sealing apparatus capable of: achieving a complete sealing property by causing a liquid or dirt having entered small irregularities in a tube inner face to flow out of a sealed zone together with a molten resin; and a heat seal with no crack caused by the molten resin having flowed into container and with an excellent compression strength. A heat-sealing apparatus for forming a packaging material,made of a laminate including a synthetic resin layer into a tubular-shape of a container, and transversely heat-sealing a tubular packaging material container filled with fluid by using a sealing jaw,having a high-frequency coil,with a ridge,on its flat pressing face and a jaw,opposing to it, wherein a first groove,is disposed on at least one pressing face of the high-frequency coil,capable of forming a synthetic resin bulge adjacent to the outer side of a zone to be sealed on a container's interior side.
