The present invention provides a double-layered foamed paper container and a manufacturing method thereof. The manufacturing method of the double-layered foamed paper container includes following steps: applying first foaming material, primary drying, applying second foaming material, secondary drying and heating and foaming. The double-layered foamed paper container includes: a paper container body, having a circumferential wall and defining a receiving space, a first foam layer disposed on at least a portion of a side of the circumferential wall opposite to the receiving space.

A container forming apparatus for forming a container from a blank includes a blank transfer station including an adhesive assembly having a plurality of adhesive applicators, and a compression station downstream of the blank transfer station, the compression station including a vertically movable mandrel and a forming tool below the mandrel. The forming tool defines a cavity therein and has an inner profile complementary in shape to an outer profile of the mandrel. Hot-melt adhesive is applied to a surface of the blank as the blank is transferred through the adhesive assembly. The blank is positioned beneath the mandrel, and the mandrel drives the blank downward into the cavity of forming tool. Compression plates fold panels of the blank, and the formed container includes a fully formed top flange.

Disclosed are methods and systems for production of fiber-based, plastic-free products are produced by a web-fed dry forming process. In some embodiments, a method of manufacturing a paper-based packaging product includes conditioning a paper web to optimize a moisture content of the paper web and to treat the paper web with at least one additive to form a conditioned paper web; and dry molding the conditioned paper web under one or both of heat and pressure to produce a plurality of finished paper-based packaging products. The at least one additive includes a stearate additive.

An apparatus for manufacturing a bottle having a paperboard outer shell and an inner pouch, a side wall of the shell formed from a blank having a main body panel for forming a cylindrical main body portion and a plurality of neck panels for forming a cylindrical neck portion. The cylindrical main body portion has a first diameter, and the cylindrical neck portion has a smaller diameter. The apparatus comprises means for forming a limit feature on an inner surface of the side wall element at a distance from an end of the side wall element, and a base insertion assembly for positioning a base element of the shell with respect to the end of the side wall and inserting the base element into an opening defined by the end of the side wall until an edge region of the base element contacts the limit feature.

A method for transporting an air-formed cellulose blank structure to a forming mould via a buffering module, includes the steps: continuously feeding the cellulose blank structure on a first endless belt unit in a first feeding direction, and redirecting the cellulose blank structure to a second endless belt unit; feeding the cellulose blank structure on the second endless belt unit in a second feeding direction being at least partly opposite the first feeding direction, where the second endless belt unit alternatingly is longitudinally moved in opposite directions relative to the first endless belt unit and a third endless belt unit, and redirecting the cellulose blank structure to the third endless belt unit; intermittently feeding the cellulose blank structure on the third endless belt unit in a third feeding direction at least partly coinciding with the first feeding direction.

A WAT carton sealing apparatus utilizes a top carton sealing assembly and a bottom carton sealing assembly to improve the speed at which cartons are sealed. The top carton sealing assembly moves vertically with respect to the bottom carton sealing assembly to seal cartons of different heights. The top carton sealing assembly may utilize top and bottom carton feeder assemblies, top and bottom tape applicator assemblies, and top and bottom WAT tape head assemblies. The feeder assemblies at least partially feed a carton through the carton sealing apparatus by engaging the top and bottom of the carton. The WAT tape head assemblies apply the water to the WAT tape and feed the WAT tape during application to the carton, while dual first and second top tape applicator assemblies and dual first and second bottom tape applicator assemblies are used to apply a double application of WAT tape to the carton.
