PCT No. PCT/SE96/00880 Sec. 371 Date Dec. 31, 1997 Sec. 102(e) Date Dec. 31, 1997 PCT Filed Jul. 1, 1996 PCT Pub. No. WO97/02182 PCT Pub. Date Jan. 23, 1997A method of achieving extended shelf life for a food includes enclosing the food in a discrete container of flexible or foldably formable material, wherein the shape of the container includes predefined crease lines for enabling the formation of the container into at least the following two container positions: a) a first container position obtained by the formation of folds along predefined crease lines such that opposing side wall panels of the container are arranged in relation to one another such that the distance between the side wall panels defines a first distance and b) a second container position obtained without the formation of folds along the predefined crease lines such that opposing side wall panels of the container are arranged in relation to one another such that the distance between the side wall panels defines a second distance. The first distance between the side wall panels is less than the second distance between the side wall panels. The method further includes treating the food in the container with heat in a treatment chamber while the container maintains the first container position, and thereafter, raising the container to the second container position. The second position of the container corresponds to that form under which the container is distributed, sold or used.
