A box formed from a plastic corrugated material with soft score lines is provided. The soft score lines are formed to enable the top flaps of the box to lay substantially flat against the outer surface of the box when folded to an open position.

A cutting machine head and a cutting machine are provided in the present invention. The cutting machine head includes a fixing plate, a cutter holder, a cutting component, a machine head lifting mechanism and a machine head rotating mechanism. The cutter holder is mounted on the fixing plate. The machine head lifting mechanism is connected to the cutter holder, and is used to drive the cutter holder to move up and down on the fixing plate. The cutting component includes at least two cutter head assemblies mounted on the cutter holder. The machine head rotating mechanism is connected to the cutter head assemblies for driving the cutter head assemblies to rotate. The rotating angle of each cutter head assembly of the cutting machine head can be controlled. The machine head rotating mechanism controls the cutter head assembly to rotate when the machine head is cutting, and the resulting cutting line has no flaws, which can ensure the integrity of the cutting pattern.

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

A carton sizing system that has a frame, a controller, one or more cutters movably mounted to the frame and operatively connected to the controller, one or more markers movably mounted to the frame and operatively connected to the controller. The carton sizing system also has a measuring means that is operatively connected to the controller and configured to determine, in use, the footprint of an open top carton and to determine the height of one or more objects contained within the carton. The controller is configured to position the one or more cutters based on the determined footprint and to cut vertical edges of the carton based on the determined height and also to position the one or more markers based on the determined footprint and height and to score or crease vertical walls of the carton between the vertical edges to at least partially define foldable panels.

A creasing unit for creating fold lines in cardboard, comprising two crease rollers, each crease roller having a circumferential protrusion adapted for indenting cardboard to create a fold line, wherein the crease rollers are rotatably mounted next to each other such that each crease roller can rotate about its own center axis and each crease roller is movable between at least a first position for creating a fold line and a second position for either allowing cardboard to pass the respective crease roller without being indented by the respective crease roller or for creating an additional indented line being less deep than the fold line.

A bulk-based packaging material is provided, comprising at least one crease line for facilitating folding of the packaging material to a package. The at least one crease line is formed as an imprint on a primary side of the packaging material, and as an embossment on a secondary side of the packaging material, wherein the imprint is formed as an elongated groove having a triangular profile.
