ABSTRACT:
A process for forming a flexible, generally tubular, three-surface, single-pleated, microwave-penetrable package for use in cooking popcorn. Two transverse seals and one lengthwise-extending seam seal the package. Venting means releases accumulated steam produced by the popping corn and the package maintains its expanded structure even after venting has commenced. A convenient means of opening the package is also provided.
