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.

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.

A sealed break-open package having: a wrapping sheet, which is folded and welded onto itself so as to define, alone, a closed containing chamber, which is designed to contain a fluid product and has a dispensing through opening, through which the fluid product can flow out of the containing chamber; and a closing system, which engages the dispensing opening in a sealing manner, so as to close the dispensing opening. The closing system having a semi-rigid plastic material sheet, which overlaps the wrapping sheet in the area of the dispensing opening, is firmly and permanently connected to the wrapping sheet, and has a pre-weakened region, which overlaps the dispensing opening and guides, following a folding of the semi-rigid plastic material sheet, a controlled breaking of the semi-rigid plastic material sheet in the area of the pre-weakened region, so as to determine the formation, through the semi-rigid plastic material sheet, of a product outlet opening.

An inflatable web is disclosed. The web includes first and second film plies sealed together via a plurality of generally transverse seals to define a first and second inflatable chambers and an inflation region. The chambers are inflatable with a fluid and operable to contain the fluid. The sealed plies have a first longitudinal edge and a second longitudinal edge. The web defines a separation region extending at least partially transversely across the web between the first and second inflatable chambers and is configured to facilitate separation thereof. The separation region includes a tear propagation line extending transversely across at least a portion of the web with an end of the tear propagation line terminating proximal to the first longitudinal edge of the web. The separation region includes a tear initiation feature including edges spaced apart from one another longitudinally to form a permanent opening in the web.
