A sealable square bottom container apparatus comprising one or more plies of sheet material. The square bottom of the container apparatus includes a continuous ring of sealable adhesive to form a substantially sift-proof bottom panel after articulation and sealing of the bottom of the container apparatus. Such a continuous ring forms a positive seal towards preventing the inadvertent migration or seepage of articles from within said container apparatus, particularly articles such as oils, steam, fluids and fine powder materials-without the need for an additional patch, sealing pastes or preliminary welds applied to the bottom of the container apparatus. Alternative adhesives such as heat sealable adhesives, cohesives and other suitable adhesives may be positioned in a pattern along the interior and exterior of the container bag to create either an adhesive to adhesive bond or an adhesive to bag material bond; to effectuate such a continuously sealed periphery without such additional bottom panel sealing pastes, patches or preliminary welds.
