摘要：
A method of manufacturing a coated paperboard container includes: providing a coated paperboard bottom blank, the coated paperboard bottom blank comprising a paperboard substrate and a first barrier coating layer on a first outermost surface of the paperboard substrate; heating the coated paperboard bottom blank; shaping the heated coated paperboard bottom blank, thereby forming a peripheral skirt portion about a periphery of a bottom wall portion of the coated paperboard bottom blank; and sealing a coated paperboard sidewall to the first barrier coating layer of the peripheral skirt portion.
