PURPOSE: To provide a package body that looks neat externally and is available for easy unsealing while being available for stacking up in numbers stably. CONSTITUTION: A container body 1, with its upper part opened, is filled with lunch food, and its upper opening is covered with a lid 3. An intermediate package body made by wrapping the container with a wrapping film 4 that is excellent in heat shrinkability and elasticity with a center sealing 5 and an end sealing 6 applied thereto is made to pass through a shrink tunnel, and thereby the wrapping film 4, being heated and heat-shrunken, is stuck fast to the container body 2 and the lid 3. A tape 7 is stuck by heating to the exterior of the wrapping film 4 on the upper side of the package body 1. By pulling the tape 7, the wrapping film 4 is torn away for unsealing. As the bottom side of the package body 1 is flat, being covered only with the film that is stretched out tightly, the package body can be stacked up in numbers, looking neat externally with no wrinkles being present on the film. |
