A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

In accordance with at least one aspect of this disclosure, a package can include a three-sided body formed of three or more body panels and an autobottom connected to the three-sided body and formed of three or more bottom panels extending from a respective body panel of the plurality of the three or more body panels. The autobottom can connect all of the three or more body panels together in a triangular shape when the three or more bottom panels are interacting with each other.

A method for collapsing a collapsible box can include pressing inward on a first side panel and a second side panel of the collapsible box along a lateral hinge, the collapsible box defining the lateral hinge extending at least partially across a front panel, the first side panel, the second side panel, and a rear panel of the collapsible box; and pressing a top panel and a bottom panel of the collapsible box together until the collapsible box is substantially flattened, the top panel and the bottom panel being hingedly coupled to the rear panel.

A foldable container moveable between a stowed configuration and a deployed configuration defining an interior area for holding bulk material is provided. The container includes opposed side panels and a bottom flap extending from a bottom edge of each side panel. A tab member extends from a distal end of each bottom flap and a tab finger extends from each tab member so as to define a hook at a distal end of each bottom flap. The hooks are interconnected so as to hingedly connect the distal ends of the bottom flaps together, thereby causing the bottom flaps to rotate between their respective stowed and deployed configuration positions as the end panels are translated between their respective stowed and deployed configuration positions. Legs are formed between the side and end panels to secure the container to a pallet and gap covers are formed to cover resultant gaps due to the formation of the legs.

A packaging container includes a first portion and a second portion that are placed on each other. Each of the first portion and the second portion has a projection polygonal surface having a projection polygonal shape, side portion polygonal surfaces extending from respective sides of the projection polygonal surface, a plurality of to-be-folded surfaces provided between the respective adjacent side portion polygonal surfaces, and a peripheral portion extending over an entirety of an outer edge. The first portion and the second portion are connected to each other at the peripheral portions by a side seal portion obtained by sealing the peripheral portions to each other, or by a connection portion obtained by folding the sheet material, and have air-tightness except for an opening.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

A corrugated cardboard blank for making a collapsible container including one or more panels joined to a bottom panel. The bottom panel is divided into first and second sectional panels on opposing sides of an interface comprising perforated portions extending from a first pair of diagonally opposing corners of the bottom panel. Each perforated portion includes an inner end, wherein the inner ends of the perforated portions are longitudinally spaced from each other. First and second fold lines extend diagonally at least partially between a second pair of diagonally opposing corners of the bottom panel and respective perforated portions. A frangible central portion of the interface extends between the inner ends of the perforated portions, wherein a plurality of unbroken flutes of the corrugated material extend laterally across the central portion of the interface.

A storage box and a semi-finished product of a second rectangular plate body thereof are provided. The store box includes a first rectangular plate body, a second rectangular plate body, and a joint module. The first rectangular plate body includes two first long sides and two first short sides, and one of the first long side and two first short sides form a first joint member. The second rectangular plate body includes two second long sides and two second short sides; two second long sides and one second short side form a second joint member. Both the first and second joint members have the same total length. The joint module includes a first joint element disposed on the first joint member and a second joint element disposed on the second joint member and engages the first and the second rectangular plate body to form an accommodating space.

A folding container mainly includes a lower base, a front plate, two opposite side plates, an upper cover, and a back plate. The folding container can be extended in use for mounting objects therein or folded for storage while not in use. During extension or folding, touch fasteners are used for fastening and fixing firmly. Thereby the folding container is not only lighter in total weight and able to be folded into a compact form while not in use, but also providing accurate positioning to keep itself from extending freely during folding process. Therefore, the folding container is more convenient to use and more practical in use.

A box can include a first side panel; a second side panel positioned perpendicular to the first side panel; a top panel joined to the first side panel; and a handle assembly, the handle assembly including: a handle portion attached the top panel, the handle portion including a tab at a side end of the handle portion, and a locking panel attached to the second side panel, the locking panel defining a cut pattern, the cut pattern including a first side cut and a second side cut, a flap defined between the first side cut and the second side cut, the first side cut diverging into an inner cut extending along a bottom of the flap and an outer cut defining a space below the bottom of the flap, a portion of the second side cut extending along the bottom of the flap.
