• oppositely disposed top and bottom panels, the top panel having a top planar surface and the bottom panel having a bottom planar surface;
• an opening for accessing an interior of the package, wherein the opening is defined in the top panel;
• oppositely disposed front and rear panels;
• oppositely disposed first and second lateral sides;
• at least one corner seal extending outwardly from the top planar surface or the bottom planar surface in a substantially perpendicular direction, wherein the at least one corner seal surrounds more than two top peripheral sides of the top panel or two bottom peripheral sides of the bottom panel;
• a leading seal extending outwardly from the first lateral side, the leading seal being folded over and secured to an outer surface of the package at the first lateral side such that the leading seal is disposed substantially in the plane of the first lateral side;
• and
• a trailing seal extending outwardly from the second lateral side, the trailing seal being folded over and secured to an outer surface of the package at the second lateral side such that the trailing seal is disposed substantially in the plane of the second lateral side;
• wherein:
• the package is formed from a single sheet of film having oppositely disposed lateral edges and oppositely disposed leading and trailing edges,
• first and second portions of the leading edge are joined by the leading seal,
• first and second portions of the trailing edge are joined by the trailing seal,
• the oppositely disposed lateral edges of the single sheet of film are joined together at an edge seal,
• the edge seal forms at least a portion of the corner seal to create a combination edge seal and corner seal,
• the two top peripheral sides of the top panel and the two bottom peripheral sides of the bottom panel are tucked inwardly toward the interior of the package and are partially covered by the leading and trailing seals, and
• the interior of the package is sealed when the edge seal, the leading seal, and the trailing seal are formed.
