摘要： A coated paperboard container includes a paperboard substrate and an aqueous barrier coating on the paperboard substrate. The coated paperboard container has a repulpability yield of 75% accepts or greater, a sidewall seam bond strength of 30 pounds per inch or greater, and a wet rigidity loss of 50% or less.

摘要： A method for manufacturing a paperboard structure includes passing a paperboard substrate through a hot-hard calender to yield a calendered paperboard substrate, the hot-hard calender including a nip defined by a thermo-roller and a counter roller, wherein a contact surface of the thermo-roller is heated to an elevated temperature. The method then includes applying a basecoat to the calendered paperboard substrate to yield a basecoated paperboard substrate, the basecoat includes a basecoat binder and a basecoat pigment blend. The method further includes applying a topcoat to the basecoated paperboard substrate.

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.
