SINGLE-SERVING FOOD PACKAGING WITH STEAM VENTS

摘要

A method of constructing a single-serving microwaveable food package is disclosed. Laser-cut steam vent apertures are formed in a line parallel to a top edge of a packaging sheet, the line comprising a first and a second set of vent apertures. The packaging sheet is folded such that a bottom edge is aligned with the top edge. The folded packaging sheet comprises a front layer and a back layer. A parallel seal is created below the line of apertures from a right edge to a left edge, wherein the front layer is sealed to the back layer along the parallel seal. The right edge of the folded packaging sheet is sealed, wherein the front layer is sealed to the back layer along the right edge. The left edge of the folded packaging sheet is sealed, wherein the front layer is sealed to the back layer along the left edge.
