A web of cleaning products and a method of manufacturing the same is disclosed. The web includes first and second carrier sheets and a plurality of pouches containing a cleaning composition. Each of the pouches is disposed in a respective depression formed in an upper surface of the first carrier sheet. A first internal atmosphere is enclosed within each of the pouches. The first carrier sheet is sealed to the second carrier sheet such that a second internal atmosphere exists between the second carrier sheet and the plurality of pouches. The second internal atmosphere has a greater absolute pressure than the first internal atmosphere so that the plurality of pouches and at least a portion of the cleaning composition in the plurality of pouches are compressed into the plurality of depressions in the first carrier sheet by the second internal atmosphere.

A method of making a web of multi-dose cleaning products may include forming first and second pluralities of internal holders in a first film, forming a first plurality of external holders in a carrier sheet corresponding with the first plurality of internal holders, and forming a second plurality of external holders in the carrier sheet corresponding with the second plurality of internal holders. The method may also include filling each of the first plurality of internal holders with a first cleaning composition, and filling each of the second plurality of internal holders with a second cleaning composition. Furthermore, the method may include sealing a second film to the first film to define first and second pluralities of pouches, folding the carrier sheet so that each of the first plurality of pouches overlaps a corresponding one of the second plurality of pouches, and sealing together overlapping portions of the carrier sheet.

This invention discloses a process for forming a pouch having an evacuated headspace containing a flowable material. The process relates to optimizing both, the evacuation of the headspace in the pouch and the accuracy of the flowable material filled in the pouch. Specifically, the present invention employs a process that includes a multiple-step or a continuous compression of the pouch headspace to accomplish the goals. Also disclosed is a vertical form-fill-seal apparatus for forming a pouch containing a flowable material and having an evacuated headspace.

The present invention relates to a laminated cellulose-based liquid food packaging material, comprising a cellulose-based bulk material layer, having through-going holes, openings or slits, an aluminium metal foil and outer layers of thermoplastic polymers. The invention further relates to the method for manufacturing the laminated packaging material and to a packaging container for liquid food packaging, comprising the laminated packaging material.

An inflatable web is disclosed. The web includes a first and second film ply sealed together. The transverse seals define first and second inflatable chambers. The web defines a separation region extending at least partially between the first and second inflatable chambers in a substantially transverse direction across the web and configured to facilitate separation of the first and second inflatable chambers. The separation region includes a tear initiation feature that facilitates tearing of the web to separate the inflatable chambers. The separation region includes a tear propagation line including a first plurality of perforations perforation is separated from an adjacent perforation by a land having a first transverse length. A tear initiation feature includes a second plurality of perforations, each perforation separated from an adjacent perforation by a land having a second transverse length, where the first transverse length is longer than the second transverse length.

An inflatable web is disclosed. The web includes a first film and second film ply sealed together via a plurality of generally transverse seals. The transverse seals define first and second inflatable chambers. The inflatable chambers are inflatable with, and contain, a fluid. The web defines a separation region extending at least partially between the first and second inflatable chambers in a substantially transverse direction across the web and configured to facilitate separation of the first and second inflatable chambers. The separation region includes a tear initiation feature that facilitates tearing of the web to separate the first and second inflatable chambers. The separation region includes a tear propagation line at least partially longitudinally offset from the tear initiation feature, and close enough to the tear initiation feature that force imparted to the web via the tear initiation feature will tear of the web through the tear propagation line.
