A package forming unit comprises plural jaw units, each having at least one respective operative assembly for engaging the tube and for at least partially forming the advancing tube, one respective sealing element for at least partially transversally sealing the tube along a transversal sealing band and a pair of interaction tabs for interacting with the tube. Each jaw unit is controllable as a function of the tube filling level in an operative configuration in which the respective operative assembly, the respective sealing element and the respective pair of interaction tabs are controlled in respective active states while advancing along respective operative portions and a partial operative configuration in which the respective sealing element is controlled in the respective active state and the respective operative assembly and/or the respective pair of interaction tabs is/are controlled in a respective inactive state while, in use, advancing along the respective operative portion.

A method for packaging products, wherein packaging material web is transported in direction of an upwardly open pair of folding claws, is cut to length while forming a planar blank of the wrapper, and the blank is positioned above the folding claws, wherein the product is metered, the product portion is pre-shaped, and the blank by placing thereon the pre-shaped product portion is folded into the claws while forming the upwardly open wrapper. Thereafter, the upward-projecting lateral longitudinal peripheries of the wrapper are folded inward onto the product portion, whereupon the transverse peripheries of the wrapper which extend perpendicular thereto are folded inward onto the product portion. The lateral longitudinal peripheries and transverse peripheries of the wrapper are folded inward onto the product portion and are simultaneously connected to one another, while the wrapper provided with the product portion is still situated in the pair of folding claws.

A hybrid packet containing deodorizing chemicals can dissolve to release the chemicals in a brine solution while still being formed using high speed packet forming machinery. A hybrid packet can be formed by feeding a sheet of dissolvable paper and a film of PVA material into the packet forming machine to form a hybrid packet having one side formed of the paper and the opposing side formed of the PVA material. The PVA sheet and paper panels are fused together by the machine to form a sealed interior compartment that holds the deodorizing chemicals. A serrated knife edge can be used to pierce the paper and PVA layers to separate individual packets. Reduced water volume in the forming operation avoids compromising the dissolvable paper portion of the hybrid packet. The packet contents can include citric acid and sodium bicarbonate.

Apparatus and method for filling bulk materials into open-mouth bags, including the following steps: a) an open-mouth bag is appended from beneath to a filling spout of a filling station by way of an at least partially upwardly motion, so that the bottom end of the open-mouth bag is freely suspended; b) the filling process is started and bulk material is introduced into the open-mouth bag so that the freely suspended bottom end of the open-mouth bag unfolds; and c) the filling spout is lowered, so that the unfolded bottom end of the open-mouth bag is supported.
