Abstract
A hermetically-sealed paperboard container is disclosed that may be produced using a conventional converting machine but at a converting temperature of at least 93° C. lower than a conventional converting temperature. The formation of pin holes or rupture on the barrier structure during the converting process can be significantly reduced, resulting in the hermetically-sealed paperboard container with enhanced barrier performances.
