Manwich, manufactured by ConAgra Foods Inc., facilitates hamburgers and uses microwave-heatable plastic barrels and lids made by Berry Plastics, which greatly facilitates consumer consumption. The hamburger is a semi-finished product that has been cooked beforehand and is served in an 18 oz. container. The inside of the container is a film pack supplied by Alcan Packaging. When eating, it is only necessary to heat the hamburger into the microwave oven, which does not require tedious preparation and cooking. The exterior of its packaging container is packaged in a beautifully printed sleeve from Caraustar.
