The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.

An overpack assembly and a method of making an overpack assembly is disclosed. The overpack assembly includes a liner positioned within an overpack. In one embodiment, the method includes making a liner including providing a first sheet including a fitment positioned over a second sheet, the first sheet attached to the second sheet along an attachment seam at an entire perimeter edge. The first sheet is pulled apart from the second sheet at a center of the liner, forming a three-dimensional liner with triangular wings. A vertical seam is formed across each triangular wing, the vertical seam being perpendicular to the attachment seam, where a length of the vertical seam corresponds to the height of the liner when in use. The liner is positioned within the overpack.

A machine a mandrel assembly includes a mandrel having an external shape complimentary to an internal shape of at least a portion of a container, a first lift mechanism operatively coupled to a first servomechanism to wrap a first portion of a blank about the mandrel, a second lift mechanism operatively coupled to a second servomechanism to wrap a second portion of the blank about the mandrel, and a folding arm coupled to the first lift mechanism and operatively coupled to a third servomechanism. A control system is in communication with the first servomechanism, the second servomechanism, and the third servomechanism and is configured to transmit a signal to each of the servomechanisms to independently control movement of the first lift mechanism, the second lift mechanism, and the folding arm to wrap at least the first and second portions of the blank about the mandrel to form the container.

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.

The invention concerns an apparatus for manufacturing of containers from blanks of a cardboard based material, said apparatus comprising: a container body forming unit configured to form a cylindrical container body from a substantially plane blank of a multilayer material comprising at least a supporting cardboard layer and a weldable layer; a welding unit configured to fasten an end closure to the container body, said welding unit comprising an inductive welding energy generator for melting of the weldable layer; and transporting means configured to transport a flow of body blanks to the container body forming unit, to transport a flow of container bodies from the container body forming unit to the welding unit, and to transport a flow of container bodies provided with end closures from the welding unit. The invention is characterized in that the transporting means comprises: a first movable gripping arrangement configured to grip at least two container bodies and move these container bodies simultaneously to the welding unit; and a transferring and positioning arrangement configured to transfer container bodies from the container body forming unit to the first movable gripping arrangement and to position the container bodies in a controlled manner to ensure that the first movable gripping arrangement can grip the at least two container bodies properly, wherein the welding unit is configured to simultaneously fasten an end closure to each of the at least two container bodies. The invention also concerns a method for operating an apparatus of the above type.

The invention is directed to straight, consistent body scores on plastic corrugated boxes and a process for making the body scores.
