Abstract

The present disclosure relates to an integrated liner-based system having an overpack and a liner provided within the overpack, the liner comprising a mouth and a liner wall forming an interior cavity of the liner and having a thickness such that the liner is substantially self-supporting in an expanded state, but is collapsible at a pressure of less than about 20 psi. The liner and overpack may be made by blow molding the liner and the overpack at the same time using nested preforms.
