In Spain and France, Heinz UK adds a twist in single-serve soup packaging with barrier plastic cups whose ribbed side panels help the container resist deformation during thermal processing of the packaged soup, and provide insulation.

The cup structure is designed to tolerate thermal processing/commercial sterilization temperatures (about 248 degrees F retort conditions) that render the soups shelf-stable and provide about 12 months of shelf life. The retortable, microwaveable, easy-open cups are developed by EDV Packaging.
