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.

Implementations described herein include films with maintained or decreased light transmittance despite a reduction in gauge. In particular, one or more implementations include a multi-layer film with each layer having differing opacity agents. The combination of the two different opacity agents in two different layers can have a synergistic effect that provide decreased light transmittance. Indeed, in one or more embodiments a multi-layer film with differing opacity agents in each layer has a decreased light transmittance despite a reduction in gauge and opacity agents.

The present invention is a method for producing an elongated protective layer for the shape-forming material of a blank, in which a protective layer is applied onto a web fed base material or sheet base material. The protective layer is applied beyond the edges of the web fed base material or sheet base material on one side or two sides in order to form a free edge that is not fastened to the base material. The multi-layer material is then cut or punched along the outline of a blank. In the places where an elongated protective layer is produced, the cutting or punching is done directly along the free edge, taking into account a margin for the elongated portion of the protective layer of the blank. The invention protects the end faces of a material for a shapeable container.

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 device (10) for optically controlling a face (13) of a blank (12) has a vacuum conveyor (20) capable of transporting the blank (12) along a path of travel (15) and which includes a conveyor belt (22) having an apertured structure of which the conveying path follows the path of travel (15) of the blank (12). A suction device (40) is suitable for pressing the blank (12) against the conveyor belt (14). An inspection device (30) inspects the face (13) of the blank (12) during its conveyance by the vacuum conveyor (20). The inspection device is located on the side opposite the vacuum conveyor (20). The suction device (40) delimits three separate successive suction sections (41, 42, 43) along the path of travel (15), including a central suction section (42) that extends opposite the inspection device (30), an upstream suction section (41) and a downstream suction section (43).

Disclosed is a folder-gluer comprises: a conveyance device configured to convey a corrugated paperboard sheet; a pair of bending bars configured to bend a first panel and a fourth panel of the corrugated paperboard sheet from 0 degree to about 90 degrees; a pair of bending plates provided in a zone where the first and fourth panels are bent from 0 degree to about 90 degrees, and configured such that distal ends thereof come into contact, respectively, with crease lines of the first and fourth panels or vicinities of the crease lines, wherein each of the bending plates is configured to be pushed and moved outwardly in a width direction, by a push-out device; a detector configured to detect a position of the corrugated paperboard sheet; and a control device configured to control the push-out device.
