Abstract: A packing and filling machine produces a container by forming web-shaped packing material into a tube, filling the tube with liquid food up to a liquid level, and laterally sealing the tube with a seal jaw and a counter jaw under the liquid level. The machine includes a diagnostic device having a pressure flange above the position of the lateral sealing under the liquid level and including sterilized gas to detect a vibration propagated when the packing material is clamped by the seal jaw and counter jaw and to diagnose the residual quantity of sterilized gas from the vibration thus detected. The packing and filling machine operating at high speed does not damage the external surface or the longitudinal sealing portion of a packing container, and even the forming/lateral sealing pressing from the opposite sides at high speed does not have a tendency to vary or oscillate the liquid level.

Abstract: A dosing bag filled with dry additive material is made using a dissolvable starch-based film. When the dosing bag with its contents are introduced into a mixture with water, it dissolves and releases its contents. The dosing bags are made in a chain. In this manner, any number of the dosing bags can be removed from the chain for use. The dosing bags are made from film material that is formed into a tube structure. While the tube structure is being partially filled, a section on the interior of the tube structure is shielded from contamination. After the partial filling, the tube is heat sealed closed in the area that was previously shielded. The shielded area is clean of contaminants and enables a high-quality seam to be formed. The shielding, filling, and sealing process is repeated multiple times to create the chain of dosing bags.
