A folded cardboard box has four longitudinal walls and a separation wall dividing the box's interior into first and second sections. The separation wall has a through-hole and a flap element at an open end of the first section. The flap element has a first flap portion at one of the longitudinal walls and a second flap portion at an adjoining longitudinal wall. The flap element can be flapped from a first state in which each of the first and second flap portions are aligned with the respective wall into a second state in which the flap element projects into the first section. A longitudinally extending wall portion, provided at one of the longitudinal walls at the open end of the first section, is connected, at its rear end, to the longitudinal wall at which it is provided by means of a seam line allowing bending of the wall from a first state in which it extends in longitudinal direction into a second state in which the wall projects from the longitudinal wall at which it is provided at about a right angle into the first section, so that the flap element, when in its second state, keeps the wall portion in its second state.

A sheet packaging material for producing a sealed package containing a food product, comprising crease lines that have sections that are angled towards each other such that at least two sides panels of the sealed package are given a trapezoidal shape.

Corrugated box assemblies, blanks, and systems for individually shipping a bag of liquid stored therein and converting an inner portion into a bag-in-box dispenser are provided. An example box assembly includes an inner portion including a plurality of walls. The inner portion includes an interior configured to receive and store the bag of liquid, which may range from about 3 to 6 gallons. The inner portion further includes a removable perforation feature defined by a series of perforations on at least one of a front wall and a front top flap extending from the front wall. A top portion and a bottom portion each include a plurality of walls that, when formed, define an opening sized to fit around the inner portion. The box assembly may be configured to pass individual box shipping test standards, such as ISTA and SIOC test standards. Methods of forming the box assembly are also provided.

A method of producing a gable-top paper or paper-board based packaging container is disclosed, the packaging container having a plurality of top-closure sub-panels, including a top-closure sub-panel (132) configured to form a pouring spout of the packaging container when the packaging container is in an open position, the top-closure sub-panel being configured to form a pouring spout comprising top-fin panel sections (182a, 182b) being at least partially hot-sealed to each other prior to a first opening of the packaging container, the top-fin panel sections abutting one another in a contact region when the packaging container is in a closed position. The method comprises the steps of: producing a blank (100) from a laminate packaging material having an outside heat sealable layer; and treating the outside heat sealable layer in a sub-region (192a, 192b) of at least one of said top-fin panel sections (182a, 182b) reducing or eliminating the heat-sealing capacity of the outside heat sealable layer in the sub-region. A related blank and a packaging container produced from such a blank is also disclosed.

The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer of paper, paperboard or other cellulose-based material, an innermost, heat sealable and liquid-tight layer of a thermoplastic polymer, the innermost polymer layer intended to be in direct contact with the packaged food product, a barrier layer laminated between the bulk layer and the innermost layer. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.

A composite package, in particular a beverage carton package for liquid foodstuffs is depicted and described which consists at least partially of a package laminate, having a package base body including package edges, an at least partially angular package base and package gable wherein the package base body defines, in an idealised manner, a package front side, package rear side and at least two lateral package sides attaching to the package rear side as well as a package laminate and a package sleeve blank for manufacturing such a composite package. In order to improve grip and ergonomy for an easy to manufacture package, provision is made for the package front side to have a positive arching at least in sections which in each case passes into a lateral package side for a grip panel to be formed at least in sections in the region of the package rear side.

A paper container having a top portion (4) that is tightly closed by bonding together opposing surfaces of first top sealing panels (20) and opposing surfaces of second top sealing panels (22), and each of side panels (16) is folded along a first side panel folding line (26) and a second side panel folding line (27) to form a flap (35) having a substantially triangular shape. The top portion (4) is formed by folding down the flaps (35) onto right and left side surfaces of a tubular body (3) through mountain-folding along front-side top panel vertical folding lines (17), front-side top panel vertical folding lines (18), and front-side top sealing vertical folding lines (23), and through valley-folding along second top portion horizontal folding lines (15) and back-side top sealing vertical folding lines (24).

A fully compostable container is provided having an enclosed body with an opening through an interior surface and an exterior surface. The enclosed body having a plant fiber structural layer configured to biodegrade in ambient conditions into nontoxic residue and a fluid barrier layer formed on a first side of the structural layer to form the interior surface of the enclosed body, the fluid barrier layer configured to biodegrade in ambient conditions into nontoxic residue. The container is gradually biodegradable when exposed to a set of factors in a natural environment and has a shelf life of six months when stored under standard commercial conditions.

The present disclosure provides a flat plate member and a packaging box, the flat member includes a plurality of sidewall regions and a connection region connected between adjacent sidewall regions, the connection region is formed with a plurality of V-shaped grooves arranged at intervals in an arrangement direction of adjacent sidewall regions on a surface facing a first side. The plurality of V-shaped grooves extend along a direction of intersection lines between the sidewall regions and the connection region, and an included angle of the V-shaped grooves is set according to a slotting influence parameter, and the slotting influence parameter comprises at least one of a bending angle of the connection region, a material of the connection region, and a number of the V-shaped grooves.
