Methods for securing a shrinkable film to a paperboard substrate and methods for making paperboard containers therefrom. In one or more embodiments, a band of adhesive may be applied about a perimeter of a paperboard substrate having a first edge and a second edge opposed to one another and a third edge and a fourth edge opposed to one another. The band of adhesive may surround a first area that is substantially free from the adhesive. A second area that may be substantially free from the adhesive may be located along a portion of the third edge, between the first and second edges. The first area and the second area may be separated by the band of adhesive. A shrinkable film may be secured to the paperboard substrate with the adhesive to produce a paperboard blank. The third edge and the fourth edge may be overlapped to form a sidewall. A bottom panel may be secured to the sidewall at or adjacent the second edge. The first edge may be curled to form a brim.

Applying padding material around shaped cutting blades includes: receiving a blade shape diagram and a rule of blade; bending the rule of blade according to the blade shape diagram to produce the shaped cutting blades; and applying the padding material around the shaped cutting blades using the blade shape diagram to produce a padded shaped cutting blade, wherein the padding material provides a spring action to quickly detach the shaped cutting blades from a plate matter.

A tool-holder column for a unit for converting a flat substrate that has two upper bearings (14, 16) each for supporting one end of an upper rotary tool (10), and two lower bearings (15, 17) each for supporting one end of a lower rotary tool (11), the flat substrate being movable longitudinally between the upper rotary tool (10) and the lower rotary tool (11), the bearings (14, 15, 16, 17) being vertically movable in opposite directions on either side of the longitudinal direction (L) of movement of the flat substrate, and a common drive for the bearings (14, 15, 16, 17) allowing the bearings (14, 15, 16, 17) to be moved simultaneously by one and the same distance in opposite directions, and including a screw device (25), the bearings (14, 15, 16, 17) being mounted one above another on the screw device (25) such that the rotation of the screw device (25) causes the linear movement of the bearings (14, 15, 16, 17) in opposite directions.

A method for converting a flat substrate (W) in a station (3) for converting a flat substrate (W) that includes a rotary cutting unit (9) and at least one rotary deformation unit (7, 8) positioned upstream of the rotary cutting unit (9) in the direction of movement (L) of the flat substrate (W), the method including: determining the conversion parameters of the flat substrate (W), such as the deformation layout and cutting layout; choosing a sleeve (13) carrying a form for carrying out the deformation depending on the deformation layout; mounting the sleeve (13) on a mandrel (12) in the rotary deformation unit (7, 8); choosing the cutting tools (91, 92) depending on the cutting layout; mounting the cutting tools (91, 92) in the rotary cutting unit (9); and starting the conversion of the flat substrate (W).

A machine for forming packing templates includes a infeed system that can feed multiple feeds of sheet material into the machine without repositioning the infeed system or forming creases or bends in the sheet material. The machine also includes a separation and cutting systems with one or more cutting tables and biased knives that cut the sheet material packaging templates. The machine also includes creasing roller(s) that forms creases in the sheet material. The machine also includes a system for reducing or eliminating the impact of irregularities in the sheet material.

A cutting and/or creasing rule is produced on a 3D printing machine which may be mounted on a board for use is a die for cutting and/or creasing a sheet of paperboard or other material into a blank for a carton. With the advent of additive manufacturing, i.e. 3D printing, it is now possible to eliminate traditional slotted die boards with generally rectangular steel cutting and creasing rules and replace same with surface printed boards with three-dimensional creasing and cutting rules.

The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.

The present disclosure relates to liners and methods of making liners. The liners may be suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc.
