摘要： A coated paperboard container includes an inner paperboard substrate, an outer paperboard substrate, a first aqueous barrier coating located on the inner paperboard substrate, and a second aqueous barrier coating located on the outer paperboard substrate. The inner paperboard substrate and the outer paperboard substrate are coupled with an adhesive. The first aqueous barrier coating and the second aqueous barrier coating include a pigment and a binder and the first aqueous barrier coating is heat sealable.

摘要： A method for applying a multi-layer coating includes passing a substrate through a nip defined by two rolls to apply a first thickness of a first liquid coating material, applying a second liquid coating material on the first liquid coating material having the first thickness as applied by passing through the nip, and controlling a thickness of the applied second liquid coating material.

摘要： A cylindrical punch head (2) includes a punch face (3) and a side surface (4). The punch face extends in a radial direction about an axis of the punch head. The side surface extends in an axial direction of the punch head about a periphery of the punch face. The side surface defines a plurality of grooves (6). Each groove extends in the axial direction of the punch head. A method for shaping a paperboard bottom blank to shape a peripheral skirt portion about a periphery of the paperboard bottom blank using the cylindrical punch head.

摘要： A packaging blank can include a paper base, and a coating disposed on and/or within the paper base. The coating can include wax and at least some calcium carbonate. The paper base can be corrugated paper board, for example. The wax can be or include paraffin wax, or any other suitable wax or substance that performs similarly to wax (e.g., for moisture proofing) and can be mixed with calcium carbonate.
