A paper-based composite container for an off-gassing product includes a paperboard can body having a substantially gas-impervious liner attached to an inner surface thereof, and a pair of substantially paper-based end closures attached to the opposite ends of the can body, each end closure defining a generally cylindrical sealing panel in contact with an inner surface of the can body. Heat-sealable materials are disposed on opposing surfaces of the sealing panel and can body. The sealing panels of the end closures are attached to the can body by heat seals. The heat seal for at least one of the end closures is discontinuous such that at least one vent channel extends through the heat seal to establish fluid communication between an interior of the container and the environment outside the container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

A container with a deep recessed bottom end construction is provided. The container includes an inner receptacle having a sidewall and a bottom wall defining an interior volume within the receptacle. The container further includes an outer sleeve wrapped around the inner receptacle with a lower end extending below the lower edge of the receptacle to form a deep bottom recess within a lower portion of the container. The lower end of the receptacle sidewall has a taper angle that is different from a taper angle of an upper portion of the sidewall. The lower end of the receptacle sidewall may engage or contact the inner surface of the outer sleeve. The outer sleeve may include reverse bend and/or a second bottom wall onto which a lower end of the receptacle may sit.

A construct for holding a plurality of containers. The construct can comprise a tray portion comprising at least a bottom panel and a side panel foldably connected to the bottom panel, a cover portion comprising at least a top panel, an open configuration for inserting or removing the plurality of containers from the construct, and a closed configuration for at least partially retaining the plurality of containers in the construct. The top panel can be opposite to the bottom panel and the cover portion can be spaced apart from the side panel when the construct is in the closed configuration. The tray portion can be for at least partially receiving at least a first container of the plurality of containers, and the construct can be for receiving a second container of the plurality of containers between the first container and the top panel when the construct is in the closed configuration.

A carton. The carton may include a floor panel; a plurality of side panels extending about a periphery of the floor panel, a front tab formed at an upper edge of a front side panel, upper side flaps extending from upper edges of a first end side panel and a second end side panel, and wherein each flap includes a side receiving slot; foldable corner gussets extending between adjacent side panels, wherein the floor panel, side panels, and foldable corner gussets are configurable to form a compartment region; a hingeable lid, including: a lid panel, a front edge flap, a side tab formed on each opposing side edge of the lid panel, and a front receiving slot formed in the front edge flap, wherein the lid panel is configured to cover the compartment region when in a closed position; and wherein the front tab of the front side panel is configured such that when the hingeable lid is in the closed position, the front tab aligns with the front receiving slot and is receivable therein and each side tab aligns with its respective side receiving slot and are receivable therein.

Materials for coating paper sleeve blanks are provided, wherein the paper sleeve blank includes a multilayer coating. The multilayer coating includes a barrier layer and a top coat. At least two polymeric layers, including a top coat, are added to one side of the paper sleeve blank and the bottom blank. A container forming machine wraps and seals the multilayer coated paper sleeve blank to the coated bottom blank.

A method for producing a bowl formed by a tray closed by a sealing film involves preparing a blank where a first and a second couples of crease lines delimit a bottom panel, two first and two second side walls, each first side wall provided of an internal flap and an external flap delimited by respective third and fourth crease lines, each second side wall provided of an internal flap and an external flap delimited by respective fifth and sixth crease lines, erecting the blank into a tray, folding the internal and external flaps of each first side wall about the respective third crease line and the internal and external flaps of each second side wall about the respective fifth crease line, applying adhesive on the internal and/or external flaps of each first and second side walls, folding the external flap of each first side wall about the respective fourth crease line and the external flap of each second side wall about the respective sixth crease line, forming a rim, applying adhesive on gaps between abutting ends of rims of adjacent first and second side walls, and attaching the sealing film on the rims.

A method for producing a cellulose product from an air-formed cellulose blank structure comprising the steps of: providing a cellulose blank structure which is air-formed from cellulose fibres; applying, in a first application step (S.sub.A1), an alkyl ketene dimer (AKD) dispersion to the cellulose blank structure, and applying, in a second application step (S.sub.A2) a latex dispersion to the cellulose blank structure arranging the cellulose blank structure with the applied alkyl ketene dimer (AKD) dispersion and latex dispersion in a forming mould; heating the cellulose blank structure to a forming temperature (T.sub.F) in the range of 100 C. to 300 C., and forming the cellulose product from the cellulose blank structure in the forming mould, by pressing the heated cellulose blank structure with the applied alkyl ketene dimer (AKD) dispersion and latex dispersion with a forming pressure (P.sub.F) of at least 1 MPa, preferably 4-20 MPa.
