A method of creating a hard cardboard material. The hard cardboard material can be made by shredding a corrugated material to a desired size to create a shredded corrugated material. The shredded corrugated material can be mixed with an adhesive material to create a corrugated mixture of the shredded corrugated material and the adhesive material. The corrugated mixture can be compressed to create a compressed mixture of a desired size. The compressed mixture can then be dried for a desired amount of time to create the hard cardboard material.

A blank has an upper surface and a reverse surface. The upper surface is printed in a conventional manner and includes outer side panels and inner side panels. Attachment regions are provided on the inner side panels of the outer surface, and corresponding attachment regions are provided on the outer side panels of the reverse surface. During assembly the respective attachment regions are arranged to face one another and an adhesive is provided therebetween. In the present method, the attachment regions of the upper surface initially have a surface tension in the range from around 34 dynes/cm to 60 dynes/cm before the upper surface is printed. The attachment regions are treated in order to maintain a surface tension in the desired range of 34 dynes/cm to 60 dynes/cm, following printing and before any adhesive is applied. This is achieved by applying an auxiliary printing medium to the attachment regions.

A line and method for the production of covered cardboard boxes are disclosed. The line includes a conveyor unit including a belt and a conveyor actuator that drives the belt intermittently in an alternating sequence of movements and stops. A feed unit individually feeds covering blanks from a reservoir to the conveyor unit in a sequence of feed instants. An erecting machine folds box blanks into corresponding boxes. A positioner individually positions the boxes from the erecting machine, in alignment on corresponding covering blanks disposed on the belt of the conveyor unit. A gluer spreads glue on one face of the covering blanks. A covering machine folds the covering blanks into contact with their respective boxes to cover the boxes. A control unit connected to the feed unit adjustably sets a phase displacement of the feed instants relative to the sequence of stops of the belt.

The present invention relates to a stacker module for a folder-gluer machine, the stacker module being located downstream of a transfer module in a direction of transportation of the folder-gluer machine and configured to receive folding boxes from a conveyor in the transfer module. The stacker module comprises a loading surface configured to receive a plurality of folding boxes in order to form a stack and to descend vertically as the number of folding boxes on the loading surface increases, and a linearly movable ejector configured to eject the stack from the loading surface. A front abutment guide configured to move between an abutment and a clearing position to retain and release the stack.

The present invention relates to a stacker module (28) for a folder-gluer machine (1). The stacker module comprises a loading surface (90) configured to receive a plurality of folding boxes and to descend vertically as the number of folding boxes on the loading surface increases, and a linearly movable ejector (76) configured to be moved from a retracted position (RP) to an extended position (DP). The stacker further comprises an upper guide (110), configured to move between a clearing position (CP) which is vertically distant from the upper surface of the stack, and a guiding position (GP), in which the upper guide is located closer to the upper surface of the stack, and wherein the upper guide is in the guiding position when the ejector is moved from the retracted position to the evacuation position.

Various embodiments are directed to repulpable and recyclable container comprising an outer liner, an inner liner, a sidewall medium arranged between the outer liner and the inner liner, the sidewall medium being defined at least in part by a sidewall flute, and one or more coating layers adhered to one or more of a first outer liner surface, a second outer liner surface, a first inner liner surface, and a second inner liner surface; wherein the container is configured such that the flute is adhered to the outer liner and the inner liner via at least one volume of adhesive configured to directly engage at least a portion of the one or more coating layers. Various embodiments are directed to a container manufacturing system configured to produce a repulpable and recyclable container. Various embodiments are directed to a method of manufacturing a repulpable and recyclable container.

A display carton for displaying a plurality of containers. The display carton includes a base having a front edge, and a back edge, a front side member extending perpendicularly from the front edge of the base and terminating at an upper edge thereof, a rear side member extending perpendicularly from the rear edge of the base and terminating at an upper edge thereof, the rear side member having a cover panel detachably affixed to the rear side member; an upper tray member having a front edge, and a back edge, the front edge extending perpendicularly from the upper edge of the front side member, the upper tray member having a plurality of first apertures; and a lower tray member, the lower tray member positioned along a plane substantially parallel to the upper tray member and the base and located therebetween, the lower tray member having a plurality of second apertures.

A food tray includes a base wall, side walls, an outer rim, and a fillet. The food tray is formed of two or more layers configured to prevent moisture or other liquid from leaking or permeating into the food tray. In particular, an adhesive layer is included between two layers of the food tray. The polyethylene layer is configured to bond the two layers of the food tray together.

According to a method for manufacturing a food packaging paper tray that can be easily separated and discarded, the paper tray is manufactured with paper of a predetermined thickness, and the bottom surface, wall surfaces and outward flange of the paper tray are coated (attached) with the synthetic resin oriented film, and thus the firm exterior shape thereof is maintained, and sealing and packaging thereof are possible by means of the sealing and packaging machine using thermoplastic films through the outward flange to which the synthetic resin oriented film is attached. Particularly, the synthetic resin oriented film is adhered, while stretched, to the bottom surface, wall surfaces and outward flange of the paper tray through an adhesive applied to the lower surface thereof, so as to ensure the waterproof function of the paper tray, and can be easily separated from the paper tray if pulled by applying artificial power.

A container blank (1), so sized and shaped as to form a shipping pack having front (2) and rear (3) walls to which there are attached, along respective fold lines (2a, 2b, 3a), side wall sections (11, 12;16, 17) each being foldable so that said front and rear walls are in juxtaposed alignment, wherein an interior open-mouthed bag (30) is adhered to the inner surfaces of the front and rear walls. When a shipping pack is erected from said container blank, the folded interior bag (30) is deployed to align with the inner volume of said erected pack so as to provide an open-mouthed container with open-mouthed interior bag to be filled and subsequently sealed for dispatch. The shipping pack is configurable in a folded flat stackable form having an interior bag in situ for storage or dispatch and is easily machine assembled or manually formed into an open-mouthed shipping pack at point of use.
