An improved paperboard pouch comprising a multilayer substrate and a method of making the same is provided. The multilayer paperboard pouch comprises an outer surface and an inner surface, wherein one of the surfaces is defined as a food contact surface. In the depicted embodiment, the properties of the polymer layer are chosen to provide adequate mechanical and barrier protection to the paper-based pouch formed on the conventional pouch-forming equipment. A method of manufacturing a multilayer paperboard pouch using conventional bag-making equipment (“CBME”) running at normal production speed for making standard plastic pouches is also provided. First, a paper is extrusion-coated and then the CBME is configured with a feeder for feeding an extrusion-coated paper intermittently for a length along a feeding path; a cutter disposed at a position predetermined for cutting one of the layers of the coated paper and forming a first side gusset, a second side gusset and a bottom gusset portions and for folding each of a first side gusset, a second side gusset and a bottom gusset portions into halves along a center line extending longitudinally thereof; and a sealer for sealing the layers of the polymer with the layers of the bottom gusset portion and the layers of the first and second gusset portions, respectively to form the finished multilayer paperboard pouch ready for sale and distribution to various retailers. It is to be noted that in the depicted embodiment various closure constructions and mechanism can be used for heat sealing the finished pouches.

A biodegradable whole leaf pillow tea bag is provided, along with a system and method for manufacturing biodegradable whole leaf pillow tea bags. The method for manufacturing the whole leaf pillow tea bags includes the steps of providing a biodegradable infusion substrate having two opposing edge; creating a sleeve from the biodegradable infusion substrate by infusing the two opposing edges of the substrate together and closing the sleeve at its bottom; placing whole leaf tea in the bottom of the sleeve; vertically feeding the sleeve containing the whole leaf tea into a heat sealing machine that will, at predetermined intervals create heat seals across the sleeve to create pillow bags; cutting the pillow bags from one another across the heat seal. In one example, the biodegradable infusion substrate may contain hemp and/or the whole leaf tea may be infused with CBD oil or other supplements. The same method of manufacturing may be used to create a biodegradable pillow bag containing coffee.

A packing machine includes a guide configured to guide a sheet of packaging material formed in a tubular shape, a sealing device configured to fuse an overlapping portion of the packaging material, a detection element pivotally attached to the guide and arranged downstream of the sealing device along a welded portion of the packaging material, a biasing member configured to bias the detection element outwardly from the guide, and a detector configured to detect the detection element that is pushed out from the welded portion.

There is described a packaging apparatus for forming a plurality of sealed packages-comprising conveyor for advancing a web of packaging material along an advancement path, an isolation chamber, a tube forming device adapted to form a tube from the, in use, advancing web of packaging material, a sealing device adapted to longitudinally seal the tube, a support structure carrying at least the tube forming device, a filling device for continuously filling the tube formed by the tube forming device, a package forming unit adapted to form and seal the packages from the, in use, advancing tube formed by the tube forming device and filled by the filling device. The support structure comprises at least one support column at least indirectly carrying the tube forming device and extending parallel to the longitudinal axis of the tube forming device.
