A bottom packaging material (50) made of corrugated cardboard arranged on the left and right, an upper cushioning material (52) placed on the upper end of the packaged object (B), and a cardboard made of cardboard fitted outside and fitted to the bottom packaging material (50) Often consisting of an outer box (60). The bottom cushioning material (5
The 1) and the upper cushioning material (52) are generally made of a pressure-resistant synthetic resin foam such as a polystyrene resin foam, and are of a one-way type that can be used almost only once.

[0003] In recent years, due to environmental problems and resource saving problems caused by disposal of such packaging materials and the like, recycling of these packaging materials and the like by repeated use and recycling has been demanded. Legislation has also been promoted.

On the other hand, in the packaging of home electric appliances and the like, it is ideal that the packaging form should be consistent in the distribution process from a manufacturer to a distribution warehouse, a merchandise distribution center, a store, a mass retailer, and end consumers. It is not desirable to make the packaging form consistent from the viewpoint of the collection route and the collection rate for recycling.

[0005] In other words, in order to improve the ease of collection work and the collection rate for recycling, for example, a plurality of items to be packaged are collected and packaged from the manufacturer to the merchandise distribution center. It is desirable to use a packaging form suitable for each case, such as individual packaging up to the consumer, and to make the packaging form as simple as possible.

[0006] However, as a conventional packaging material, there is a material which facilitates separation of a packaging material such as an outer box made of corrugated cardboard from a cushioning material made of a synthetic resin foam. For this reason, no particular consideration is given to making the packaging form different from the manufacturer to the commodity distribution center and from the commodity distribution center to the end consumer, and to make a simple packaging form suitable for each.

[0007] The present invention has been made in view of the above, and in particular, in order to facilitate the collection work for recycling such as repeated use and to improve the collection rate, simple packaging without using an outer box is possible. In addition, the present invention provides a bottom packaging material that can be suitably used for collective packaging from a manufacturer to a distribution center and individual packaging for end consumers, and has excellent workability at the time of collection. Further, the present invention provides a bottom packaging material that can be stacked stably and collectively packaged, also serving as an upper cushioning material that protects the top portion of the package.
