Abstract (en)
[origin: WO2021054942A1] A retortable package includes a body defining a perimeter and a peripheral seal formed along the perimeter of the body. The peripheral seal includes at least one peripheral self-venting region and at least one peripheral non-venting region. The retortable package further includes an intermediate seal formed within the perimeter of the body and contiguous with the peripheral seal. The intermediate seal divides the body into two compartments. The compartments receive respective products therein. Upon heating of the products, the intermediate seal ruptures before the at least one peripheral self-venting region ruptures. Further, the at least one peripheral self-venting region ruptures before the at least one peripheral non-venting region ruptures.
