Claim:
A method for assembling a fin seal container comprising the steps of: folding a container blank into a three-dimensional body that defines an internal volume and includes an end portion that defines an opening into said internal volume, said end portion including a first fin seal panel having inner and outer major surfaces and a second fin seal panel having inner and outer major surfaces; folding said end portion such that said inner major surface of said first fin seal panel is positioned adjacent to said inner major surface of said second fin seal panel; separating said first fin seal panel from said second fin seal panel; with said first and said second fin seal panels separated, treating at least one of said inner major surface of said first fin seal panel and said inner major surface of said second fin seal panel; and after said treating step, pressing said first fin seal panel into engagement with said second fin seal panel; wherein said first fin seal panel comprises a pre-formed fold line; wherein said separating step comprises pivoting a portion of said first fin seal panel about said pre-formed fold line; and wherein the pre-formed fold line is sufficiently below the top edge of said second fin seal panel so that a sufficient amount of the inner surfaces of the first and second seal panels are exposed.
