  • FIG. 2(a) is a view as seen from the original plane ABDC and FIG. 2(b) is a view as seen from an angle rotated 90 degrees from the surface of the original ABCD. Since the packaging container 6 is formed as a tetrahedral structure, there is resistance to external pressure and the contents can be clearly viewed when a transparent material is used as the material that forms the bag assembly 1. Nitrogen or carbon gas is sealed in the packaging container 6 as necessary, and the degradation of freshness of the contents can be prevented.
  • a resin film or resin sheet can be used as the material for the bag assembly 1.
  • a resin that may be used include polyethylene, polypropylene, and other polyolefins; and polyester, polyamide, polycarbonate, polystyrene, polyvinyl chloride, polyvinylidene chloride, a copolymer of ethylene and vinyl alcohol (trade name: EVAL), and the like.

  • lettuce, spinach, or another leafy vegetable V is the packaging object, and when this object is sealed inside the packaging container 20 whose basic shape is a tetrahedral body, the body does not have parallel or opposing surfaces. Therefore, when an external force is applied, the external force is dispersed, and damage to the leafy vegetable can be reduced without external force being applied unchanged to the leafy vegetable V as in the case where the vegetables are sealed in a box-shaped packaging container.
  • lettuce, spinach, or another leafy vegetable V is the packaging objec sealed together with air inside the packaging container 10 whose basic shape is a tetrahedral body. Therefore, air layers are interposed between adjacent vegetables and between the vegetables on the surface and the bag assembly 12.
